Study on Cyclic Utilization of Converter Dust-removal Resource for Panzhihua Steel

Based on the characteristics of converter dust-removal ash in Panzhihua Steel, synthetic slag forming medium, final slag regulator, both of which are used in semi-steel converter steelmaking, and coolant used in vanadium extraction are developed.The effects of synthetic slag forming medium and final slag regulator on terminal oxidation of semi-steelmaking, converter' splash, consumption of iron and steel materials as well as converter dephosphorization and so on are analyzed.The using ways of converter dust-removal resource are expanded.Then, it can make dust-removal resource get much better utilization in Panzhihua Steel and decrease pressure in environmental protection.
