| 摘 要： | 本文开发了一种预熔型精炼合成渣,具有高碱度低熔点的特性,实验室条件下,平均脱硫率为84.5%.在工业实验中,根据钢种出钢要求,设计了分钢种的加料方案.实验结果表明,本精炼渣可以达到100%出钢化渣率,精炼时间缩短了11min.与原工业渣系相比,使用本精炼渣后,VD前钢中氧和氮含量分别降低了7×10-6和12×10-6,VD后钢中氧和氮含量分别降低了5×10-6和15×10-6.脱硫率也得到了大幅提高,从电炉出钢至VD后吊包的脱硫率为92%,最低硫含量达到30×10-6.

| Abstract: | One type of premelted refining slag was developed in this article. This new type refining slag has the characteristics of high basicity and low melting point. Under laboratory conditions,the average desulfurization rate reached to 84.5%. During the industrial experiment,the charging schemes of steel grades were distinct. The experimental results indicated that using the new type refining slag the slag-melting rate was 100% at the end of tapping and the refining time was shortened by 11 min. By comparison wi... |
