Based on the reaserch of Laiwu Steel beam blank pouring steel during refining process, the existing slag system was improved. The slagging time was reduced to 5min by using new refining slag. The results of thermodynamic calculation indicate that the melting point of new refining slag decreased by 50~200 ℃ and liquid slag proportion increased by about 40%. Besides, the Sulphur content in new refining slag increased by 36.5%and no reaction causing aluminum increasing in the steel occurred by using new refining slag.
