介绍了转炉在出钢过程强化钢水净化的工艺,实验结果表明:该工艺能在较短时间内降低钢水及熔渣氧化性,利用出钢过程良好的动力学条件进行脱硫,从而提高了LF精炼炉的精炼效果,显著提高了钢水纯净度.通过对工艺的优化和完善,可使部分钢种不经LF炉处理也能满足品种钢性能的要求,进而缓解LF炉作业压力,减少了LF增碳增硅的几率,提高了低碳低硅钢的成分命中率. The process of purifying molten steel in the process of tapping was introduced. The experimental results show that the process can reduce the oxidizability of molten steel and molten slag in a short period of time, and desulphurize by using the good kinetic conditions in tapping process, thus improving the LF refining The refining effect of the furnace significantly improves the purity of the molten steel.Through the optimization and perfection of the process, some of the steel grades can meet the requirements of the steel properties of the varieties without the LF furnace treatment, thereby alleviating the working pressure of the LF furnace and reducing the LF increase Carbon silicon increases the chance of raising the low-carbon low-silicon steel composition hit rate.
