DRI-HIsmelt The traditional ironmaking plant is a long process technology that requires the support of three plants: coking plant, sintering plant, and pellet plant. It has high investment, large land area, serious pollution, and high cost. The use of HISMELT ironmaking process can reduce investment, eliminate coking and sintering processes, reduce pollutant emissions during the smelting process, improve smelting efficiency. At the same time, the composition of molten iron is easy to control, low consumption, and low cost. Compared with traditional blast furnaces, it has obvious advantages in ironmaking cost and environmental protection, which meets the long-term development needs of ironmaking technology.
