Summary of reducing cost and increasing efficiency in ironworks
20 1 1 Since the second half of the year, the ironworks have been putting pressure inward, taking stabilizing blast furnace production as the core, reducing costs and increasing efficiency as the means and maximizing benefits as the goal, constantly improving technical and economic indicators and striving to create a new situation in production and operation. The main work completion at this stage and the next work plan are reported as follows:
First, the effectiveness of reducing costs and increasing efficiency.
1, production technology
(1) One hundred days of tackling key problems have achieved results.
20 1 1 June, the whole company started? One hundred days to solve the problem? During this period, the output of pig iron was 295,002 tons, exceeding the planned output of 2,902 tons, and the qualified rate of pig iron was 100%, which ensured the provision of high-quality molten iron for steelmaking. At the same time, we deeply tap our own potential, firmly establish cost control as the center, take various measures, and have achieved outstanding results. In June, July and August, the assessment cost of pig iron was 2 150.35 yuan/ton of iron, which was lower than the planned cost165,438 yuan +0.62 yuan/ton of iron, and the total cost was 3,426,900 yuan. The comprehensive coke ratio is 534 kg/ton, which is 6 kg/ton lower than planned. The internal control rate of furnace temperature reaches 83%, which is higher than the company's internal control standard 13 percentage points.
(2) Carry out coke classification.
Because the company has no coking, the coke used in blast furnace is outsourced. Because there are many coke manufacturers, the composition, particle size and strength are unstable, and the powder content is high, which affects the smooth operation of blast furnace and causes great cost pressure.
So, 10? 25mm sieve is eaten as coke, and the proportion is adjusted according to the furnace condition. On the one hand, the quality of coke charged into the furnace is guaranteed, and at the same time, because coke particles enter the furnace with sinter, the soft melting layer becomes thinner, the resistance loss of the material column is reduced, and the air permeability is improved, so that the reduction process of ore is improved, and the effect of reducing coke ratio and ensuring smooth furnace condition is achieved.
(3) eat a piece of ore.
Because the grade of lump ore is similar to that of pellet ore, but the unit price of lump ore is lower than that of pellet ore, the Ironmaking Plant has formulated a "lump ore blending scheme" to increase the proportion of lump ore by 20 12 1? During the period of 65438+ 10, the lump-ore ratio was 1.8%, and the highest was 4.5%, which kept the furnace condition stable and effectively reduced the cost of pig iron.
(4) eat secondary cola.
20 12, coke prices rose sharply. In order to reduce procurement costs, 8? In September, according to the purchasing and inventory situation, the Ironmaking Plant made a detailed "Matching Plan of Coke Low-cost Materials".
(5) eat vanadium and titanium powder.
In order to reduce the production cost, 20 12 1? In June 65438+ 10, a certain amount of vanadium and titanium powder was added to the lunar cluster, 1? In July, the proportion of food is 20? 40%, the proportion of food ration increased to 100% in August,
(6) Eat FMG powder and Indian powder.
On August 27th, 20 12, the ironworks began to eat the sinter containing 10%FMG powder. After 28th, the proportion gradually increased to 40%, and on September 20th, it increased to 50%, during which the sinter quality became worse (in September, the sinter strength was only 70.83%, and the content of small particles increased, and the measurement under the trough was 5? 10mm is 38.77% and the powder content is 5.88%), which leads to unstable airflow. In view of this feature, in order to ensure the stable and smooth operation of No.3 boiler, the ironmaking plant has formulated the operation rules of mixing FMG powder.
On February 4th, 20 12, sintering with Indian powder was started (30% on February 4th, 65438+50% on February 5th), and the branch organized a special meeting to formulate the production organization plan with Indian powder, which ensured the stable and smooth operation of the blast furnace.
(7) reduce the comprehensive focal ratio
In 20 12 years, in order to reduce the coke ratio, the ironworks took the following measures: formulating and implementing the furnace temperature incentive plan and blast temperature assessment plan, stimulating the furnace temperature and blast temperature, improving the coal injection ratio and coke ratio, optimizing the blast furnace operation, eliminating the chaos of large furnace conditions, stabilizing the [Si] deviation, realizing low silicon smelting, and formulating key projects for reducing the coke ratio in the ironworks. The proportion scheme of coke reduction in ironworks in 20 12 years is 1. doc >； Through the above measures, the comprehensive coke ratio of 20 12 is 8.52Kg/t lower than planned, which greatly reduces the cost before iron.
(8) Understand the market dynamics and adjust the raw fuel structure in time.
Combined with the supply department, timely grasp the purchase price of raw fuel, accounting for coal injection, coke, iron powder ratio, raw ore. According to the price of bituminous coal, mixed injection has no advantage, so the company is required to inject anthracite into the blast furnace from165438+1October 22nd.
2. Technical transformation
(1) Carry out coal injection reform, increase coal ratio and increase bituminous coal mixed injection ratio.
In order to reduce the coke ratio, aiming at the problems of insufficient nitrogen pressure and low coal powder output per hour, coal injection is restricted. In August of 20 1 1 year, the ironmaking plant timely coordinated the energy center to increase the nitrogen pressure, reformed the coal injection, increased the output by about 2 tons per hour, and improved the coal injection ratio of No.3 boiler to a certain extent, from 94.8kg/t in May to 60 in August.
20 1 1, 1 1, coal injection system transformation,1October 27th1# and 3# blast furnace simultaneously inject coal.
20 12 03 19 the original bituminous coal feeder belt scale was replaced by a reducer with a speed ratio of 48, and the weighing weight was increased, so that the bituminous coal ratio was increased to 40%, which provided a guarantee for improving the coal ratio.
(2) Modification and optimization of bag dust removal system for blast furnace.
During the shutdown of No.2 boiler in 20 1 1 year, 3 boxes of No.2 boiler were used, which solved the problem of insufficient bag boxes of blast furnace, and the life of bag boxes of 1 boiler was prolonged by 2? 3 times, reducing the cost by more than 200,000 yuan. In the same month, the bag-type ash discharging ball valve seal of 1# boiler was reformed, saving 654.38 million yuan.
(3) Reforming the charging system of blast furnace to reduce the ore return rate of blast furnace.
Limited by the site, there are many belts in the charging system of blast furnace, and there are also many transfers this time. After many transfers, the sinter return rate and small particle size increase, which restricts the production of blast furnace and increases the cost. Therefore, 20 12 and 1.2 reformed the charging system of No.3 blast furnace and put it into use on 1.6. After the implementation of the transformation project, the sinter directly enters the bunker on the chute without passing through the transfer bin, which reduces the return rate of sinter and improves the particle size of sinter entering the furnace.
(4) In the second half of 20 11,through a series of technical innovation activities, such as reforming the down pressure system of No.3 furnace trough, reforming the cooling water filter, replacing the mesh filter material in the mesh ring, and making the skip protection device for1furnace hoist, the unplanned maintenance rate is the best index of zero. Among them, 20 1 1 year 6? In June 1 1, the slow air rate of the equipment is zero.
3. Auxiliary support
(1) During the single-furnace production of No.3 blast furnace, the utilization of coal grinding capacity is large, and the pulverized coal is ground in advance during the non-peak hours, which reduces the coal grinding time during the peak hours and saves about 65,000 yuan/month.
(2) Control the dust removal fan and slag flushing pump, adjust the speed of the fan to the lowest when the iron is not tapped, reduce the load, and stop using the slag flushing pump at the same time, effectively reducing the power consumption.
(3) During the preparation of 3)FMG powder, coordinate the coke car transportation, so that the transportation time is reduced from the original15min/car to the present 9min/car, which not only ensures the position, but also reduces the belt running time and power consumption; At the same time, coke is directly put into storage, which reduces the number of coke transfers, avoids vehicle crushing and reduces the powder entering the furnace.
(4) In order to reduce the jumping of the feed, ensure that the material level on the tank is below two meters; Check twice in each shift under the trough, and find that the sinter contains more than 3% powder, and control the vibration screen amplitude and blanking speed in time; The above two factories assign special personnel to take charge of spot checks, and the effect is good after implementation, effectively controlling the powder content in the furnace.
4. Independent management and proposal system
20 1 1 get the company? Autonomous management? And then what? Proposal system? Title of advanced unit with outstanding performance
In 20 12, the ironworks successfully organized and completed six, seven and eight independent management activities, and carried out activities in six aspects: cost, production, energy, maintenance, environmental protection and others, which effectively solved the practical problems existing in the production process. By the end of June, 1 1, * * released 32 independent business activities, creating economic benefits of 1 1.46 million yuan.
20 12 ironworks actively organized and vigorously publicized the proposal system. 1? On June+10, 5438, the Ironmaking Plant * * * accepted 206 proposals, with 26 exceeding the plan. It is estimated that the annual profit can reach more than 5 million yuan, which will also play a great role in environmental protection, reducing potential safety hazards and reducing the labor intensity of employees.
5. Clean up the warehouse and check the warehouse
On October 2012165438+10, according to the company's plan, idle and scrapped materials will be returned to the warehouse, and a ledger will be established for fixed management.
20 12 1? 165438+ 10, the monthly pig iron output was 763,700 tons, the qualified rate of quality was 100%, and the internal control rate of furnace temperature was 87. 16%. 1? In June 165438+ 10, the average pig iron assessment cost was 2787.38 yuan /t, which was less than the planned cost 1 1.5 1 yuan/t. Because of the obvious effect of reducing cost and increasing efficiency, it was rated as the best team in 20 12 by the company.
Second, reduce costs and increase efficiency work plan
In the past year or so, ironworks have made some achievements in reducing costs and increasing efficiency. However, due to the constraints of specific process configuration and raw fuel conditions, the cost of pig iron is still high, which needs to be further tapped.
1, and continue to tap the potential in reducing power consumption.
At present, the power consumption is still high for the following reasons:
(1) Since only No.3 boiler was produced in September, the furnace work was uneven after eating low-priced materials (bottom cleaning and secondary coke) and FMG powder, the pig iron output was low, and the capacity was appropriately limited, resulting in an increase in electricity consumption.
(2) 1# boiler and 2# boiler have stopped production, but the two cooling pumps are running normally, resulting in high power consumption.
(3) When the fan of 3 # boiler works normally, the air bleed valve is in the open state, and the opening is? 15 degrees, with high power consumption.
Countermeasures: Contact the fan manufacturer to solve the problem of long-term opening of the fan vent valve, strictly control the start-stop time of slag flushing water, and save power consumption.
2. Strengthen the technical transformation of equipment, repair old equipment and make use of waste, ensure the quality of work, and further reduce the cost before iron.
3. Production technology
Adhere to the established policy of blending Indian powder at low price, and continue to explore the smelting technology of blending Indian powder and vanadium-titanium powder to ensure the stable and smooth production of blast furnace.

Advanced personal report materials for reducing costs and improving efficiency
When cleaning the drainage ditch of the enterprise station, the mud in the ditch is more than a foot thick. I'm not afraid of being dirty or tired. I led the team to clean until 8: 00 pm, and it took me one day to complete the required workload of 10. In the process of recycling alumina waste, my comrades and I overcame the unfavorable factors such as cold weather and few people. Two shifts cleaned more than 80 vehicles/kloc-0, and successfully completed the cleaning task. In the peeling work, I overcame the unfavorable factors such as hot weather and few people, and accomplished the peeling task brilliantly every time. Due to outstanding work performance, it was awarded as Shanxi Branch on the occasion of Youth Day on 20 10 * * * * * *? Top ten outstanding young people? , commended and rewarded by superior leaders.
Third, do a good job in energy conservation and emission reduction, and put an end to leakage.
In order to put an end to all kinds of waste, I started from myself, dug deep and searched for dead ends that might lead to waste. In the heating season last year, in order to reduce unnecessary waste of gas, we took the initiative to clean the heating in rooms where no one was resting and working, saving a lot of gas. We also educate workers to resolutely put an end to the phenomenon of ever-burning lamps during the day and running water at ordinary times. Last winter, the cold weather cracked the water tank in the toilet. We found out in time that we bought sanitary ware and other spare parts, repaired the water tank and reduced the waste of water resources. Welders sometimes forget to cut off the power when they are at work. In order to put an end to this wasteful loophole, I have formulated a strict assessment method. The welder is required to completely cut off the power supply during the intermission of work to prevent waste, and the employees respond positively, so this system can be implemented.
Fourth, tap the potential and reduce consumption to reduce maintenance costs.
In our work, we always aim at reducing the cost of various materials and carefully calculate the maintenance work. In the process of repairing the vehicle brake three-way valve, what should we take as a guide? What can be repaired must be repaired, and never replace it with a new one. In the first quarter of this year, two brake three-way valves were repaired, saving more than 4000 yuan. In the qc group activities carried out last year, we adopted? Reduce the number of round pins on the cover of aluminum-oxygen tank car? Carry out public relations activities for the project, and won the first prize of qc achievement of the Ministry of Transport at the end of the year. Only this one can save more than 4000 yuan in material costs every month. What are we going to do this year? Reduce the welding quantity of bolster of self-provided gondola car? As a subject, continuing to carry out qc activities will greatly reduce the hanging of vehicles, and play a positive role in accelerating the utilization rate of self-provided gondola cars and completing the production and transportation tasks.
Now, the clarion call for comprehensive recovery of alumina production system has sounded, and we will face a more severe situation and task. If you don't advance, you will retreat. Facing the heavy responsibility entrusted by the times, I will work hard with higher fighting spirit and more rigorous work style. I also believe that our enterprises will certainly improve their anti-risk ability and long-term development potential in the baptism of the economic crisis; I believe that our enterprises will accumulate wealth in the ups and downs of the market economy and sail far and wide.
Summary of rationalization proposals to promote cost reduction and efficiency increase
? Your rationalization proposal won the prize again! ? In the crushing workshop of the concentrator, everyone envied Wang Jianhua. Wang Jianhua is an electrician in the crushing workshop. In the recent commendation of rationalization proposals of concentrator, Wang Jianhua was repeatedly listed. What rationalization suggestions does he have? Electric vibration transformation of shielding room? 、? PYD Cone Crusher Manufacture and Installation of Anti-smashing Device? Won the second prize and the third prize.
In the concentrator, there are not a few Rainbow Jianhua workers who actively put forward suggestions on reducing costs and increasing efficiency. In order to make the trade union work better serve the cost reduction and efficiency improvement center of the whole plant, after the adjustment of the cost reduction and efficiency improvement index, the concentrator trade union quickly issued the concentrator? Recognize the crisis and meet the challenge? Strive to achieve the annual goal, further stimulate the potential and enthusiasm of employees, and contribute to reducing costs and increasing efficiency. The factory trade union broke with the convention, and every time the workers put forward a rationalization proposal, whether they won the prize or not, they rewarded 5 yuan with money. When this move came out, the response was strong. The workers said that although 5 yuan has little money, the degree of attention it shows can be seen, and it is necessary to repay the concentrator with practical actions.
To solve the problem of front-line workers? Golden idea? The factory trade union requires all workshops and departments to give full play to the role of technicians, and form a joint research team with technicians and front-line workers to let technicians? Sneaking around? At the grassroots level, for employees? Golden idea? * * * With the excavation, summary and refinement.
Wang is the head of electrical technology in the maintenance workshop. He found that there are many types of small oil stations used for equipment lubrication, which is difficult to maintain. He used his brains to convert the original small oil station into a new programmable controller, which changed the problems of aging, many faults and difficult maintenance of the equipment in the small oil station. In recognition of his contribution, the concentrator awarded him? Golden idea? Awards.
In the vigorous rationalization proposal activities, workers generally welcome the practice of shortening the commendation period of rationalization proposal in concentrator (from once a year or half a year to once a month). Due to the timely collection of suggestions, timely research and adoption, and timely organization and implementation, rationalization suggestions have played the greatest role in reducing costs and increasing efficiency.
The reporter learned that from July to June this year 10, the concentrator collected more than 40 rationalization suggestions from employees10, creating benefits of more than 2.3 million yuan. In the important period of sprinting to the annual production task, reducing costs and increasing efficiency, the concentrator trade union will continue to promote the smooth completion of the annual production task by increasing publicity, increasing incentives and making good use of achievements.
