Abstract: Hot recycling of continuous casting slag from ladles in WISCO is introduced in this paper.The method was carried out to use returning liquid continuous casting slag by hot online recycling in LF furnace.The changes of LF refining end slag and its effect on the quality of molten steel have been taken for in-depth analysis.Results showed that the consumption of LF furnace slag materials and deoxidizing agents were greatly decreased by online recycling of hot slag,the consumption of lime and refining slag and deoxidizing agent(aluminium alloy)were decreased by 1.01,0.21,0.20 kg/t, respectively.Power consumption was decreased by 3.66kWh/t.The residual molten steel from casting was returned to use,the consumption of metal materials was decreased by 3.0kg/t.
