Sintering plant is the pretreatment plant of iron ore, which mainly mixes iron ore with other auxiliary raw materials, sintering, cooling and other processes to make sintering furnace material. Sintered ore is one of the main raw materials in blast furnace smelting process, which has good permeability, mechanical strength and reduction performance. Sinter reduces iron oxide in iron ore to metallic iron through the reduction reaction of blast furnace, thus achieving the purpose of ironmaking.
