Abstract: In desulphurization slag skimming process, the hot metal of different heats shall be brought into slag pot, led to freeze together and hard to break up, in view of this situation a new partitioning agent-lamination material (/%: 6 ~ 15SiO₂, 20 ~35 CaO, ≥50MgO, 5 ~ 15FeO) is developed and manufactured by using waste material in steelmaking system at No2 Steelmaking Plant. With using this lamination material not only the treatment of desulphurization slag is easier but also the yield of slag iron increases to 92% from original 10%, and the environmental pollution is lightening.

摘要： 在脱硫扒渣的过程中,不同批次铁水包扒出的铁水会相互渗透,导致渣铁凝固结成大块,难以破碎,针对这一问题第二炼钢厂开发了一种使用炼钢系统自产废料制备脱硫渣隔断剂(/%:6～15SiO₂、20～35CaO、≥50Mg0、5～15FeO),使用该隔断剂后不仅降低了脱硫渣的加工处理难度,渣铁回收率由原来的10%增加至92%以上,而且减轻了环境污染。
