Abstract: According to the studied system of liquid steel, refining slag and alloy in 120 t LF refining process, based on energy-balance principle model the prediction model for temperature of refining liquid steel has been established. According to steel grade, liquid weight and temperature, aim tapping temperature and treated time, adding amount of refining slag material and alloys as well as various heat loss to get required input electric energy, the reasonable electric supply curves during refining are determined. And the temperature of liquid is predicted according to parameters of electric supply and process at worksite. Examination results on 20 heats steel 50RH1 (% : 0. 48C ~ 0. 50C, 0. 22 ~ 0. 30Si, 0. 60 - 0. 70Mn) show that the error of temperature of liquid between model predicted value and measured value are ±5℃.
