攀钢转炉尘资源循环利用技术研究

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

根据攀钢转炉除尘灰特性,研制了用于半钢转炉炼钢的新型复合造渣剂和终渣调渣剂以及用于转炉提钒的冷却剂。分析新型复合造渣剂和终渣调渣剂对转炉冶炼终点氧化性、溅渣护炉、钢铁料消耗以及转炉脱磷效果等影响,拓展了转炉尘资源的使用途径,使攀钢转炉尘资源得到较好的循环经济利用,减轻环保压力。

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.
