Abstract:Practice shows that sludge pellet is added in the form of slugging agent and coolant in converter steelmaking, which has the obvious metallurgical effect. Through contrast test, the following conclusions can be drawn: using sludge pellet in converter smelting process can achieve rapid slugging, facilitate dephosphorization reaction, improve the inverted furnace C-T-P hit ratio, reduce erosion, and reduce the content of inclusion in molten steel to improve the quality of low times microstructure continuous casting. The process can lower steel material consumption, the consumption of lime, oxygen consumption, shorten the smelting cycle, and reduce the smelting cost. The sludge wet dedusting system, converter sludge pellet balling process and application technology were also elaborated.
