摘　　要：针对LF精炼脱硫时钢包内衬严重侵蚀的问题,将LF炉精炼渣进行调整,使用铝酸钙体系取代萤石的无氟精炼渣。调渣后钢包的侵蚀状况得到明显改善,精炼数、精炼比以及拆包残厚得到较大幅度提升。新渣系的流动性以及脱硫效果能够满足生产要求。In order to tackle with the problem of serious erosion of ladle lining during the desulfurization of LF refining,LF refining slag was adjusted and calcium aluminate system substituted fluorine free refining slag with fluorite.After the adjustment of the slag,the erosion conditions on ladle were improved greatly and refining number,refining ratio and remaining lining thickness after demolishing all increased substantially.The liquidity of new slag system and desulfurization effect could meet the production requirement.
