For China's goal of reducing energy consumption per unit GDP by 4% last year, "although the steel industry has made great efforts, it has not achieved this goal." Qi Yongxin, director of the Information Department of China Iron and Steel Industry Association, said in an interview a few days ago.
Energy saving and consumption reduction has always been a serious problem faced by the steel industry. During the "Eleventh Five-Year Plan" period, the state proposed to reduce the energy consumption per unit of GDP by about 20%. Qi Yongxin believes that it is useless to just shout slogans, and it is necessary to further use automation technology and information technology to promote energy saving and consumption reduction in the steel industry. After investigation, the reporter found that energy management system (EMS), manufacturing execution system (MES), equipment automation and new technology are the three magic weapons to help iron and steel enterprises save energy and reduce consumption.
Need to improve the environmental management system
The energy consumption of steel plants accounts for 20% ~ 40% of the steel cost, so it is imperative to build a centralized and unified energy management system (EMS). Cong Liqun, deputy general manager of Shanghai Baoxin Software Company, said: "By analyzing, processing and processing the energy data through the energy management system, the staff can grasp the status of the system in real time." He said, for example, when there is a peak or trough of electricity consumption in an enterprise, the staff can understand this demand from a global perspective and make reasonable adjustments to the power system to ensure that the system runs in the best state.
