摘要
Abstract
In order to improve the deep desulfurization efficiency of the LF furnace,the timing of refi-ning deep desulfurization slag formation in the LF furnace was optimized through industrial experiments.When the temperature of the molten steel increased to above 1560℃,lime was added and a certain amount of refining agent was added to replace fluorite,rapidly forming a CaO-Al2O3-SiO2 slag system.The CaO/Al2O3 ratio of the refining slag decreased from 2.5 to2.0,which can improve the fluidity of the LF refining slag,increase the desulfurization efficiency of the LF refining by more than 20％,and reduce the amount of lime added by more than 30％.After continuous casting,the occurrence rate of crust on the sur-face of the steel water tank decreased by 86.67％.Reduce the erosion of fluorite on steel water tanks and minimize environmental pollution.关键词
