Abstract：Problems of SRP steelmaking process which is difficult to be adopted in most old steel mills except for newly built steelworks were introduced. Meanwhile，the reason why the popular process MURC is not suitable for semi-steel steelmaking processes was introduced in detail. Based on the 200 t steelmaking converter of Pansteel Group Xichang Steel and Vanadium Co.，Ltd.，for the?recycling?of hot slag in the process of semi-steel steelmaking in converter，a new technique that “the slag of the first heat was all reserved，and the slag of the next heat was poured mostly” was put forward on the basis of the theoretical analysis of dephosphorization. The new technique has achieved significant results in the semi-steel steelmaking. The dephosphorization efficiency is significantly improved，the average flux consumption of converter decreases to 47.64 kg/t，and the average lime consumption is 13.95 kg/t. The new technology has a good effect on reducing steel material consumption and improving converter life-time.
