摘　　要：基于莱钢异型坯浇注钢水精炼工艺,对现有渣系进行改进。使用新型实验渣后精炼渣的成渣时间缩短5 min。通过热力学计算发现新型实验渣熔点降低50~200℃,液渣比例提高约40%,精炼渣中硫含量升高36.5%,且新型实验渣精炼过程中不会发生增铝反应。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.
