Research on Control Practice of Harmful Elements in High Puri-ty Pig Iron for Blast Furnace Smelting of Wind Power
High purity pig iron for wind power requires that the molten iron contains low levels of harmful impurities such as phosphorus,sulfur,and titanium to ensure the quality of castings.Benxi Iron and Steel Beiying Ironmaking Plant utilizes 530 meters 3 Starting from the study of the reduction laws of harmful elements,a series of measures are taken to optimize the selec-tion of raw material varieties,improve the quality of raw materials,implement full powder sintering,optimize blast furnace oper-ation and adjustment,control the temperature of the furnace hearth,increase the top pressure,select appropriate slag alkalini-ty,and control a reasonable theoretical combustion temperature in front of the tuyere,starting from the mature production pro-cess of blast furnaces.These measures include optimizing the selection of raw material varieties,improving the quality of raw materials,implementing full powder sintering,optimizing blast furnace operation and adjustment,controlling the temperature of the furnace hearth,increasing the top pressure,selecting appropriate slag alkalinity,and controlling a reasonable theoretical combustion temperature in.
