摘　要: 本文通过生产数据,论证了转炉采用石灰石造渣炼钢的相对合理方案。阐述了石灰石应用于转炉炼钢的优越性,通过前期石灰石替代石灰煅烧分解造渣,降低了转炉前期的吹炼温度,增加钢水炉渣的搅拌力,为转炉炼钢节约了生产成本,创造了良好的经济效益。

Abstract: With analyzing of the production data,the plan of making slag with limestone in the converter steel- making process has been proved relatively reasonable. The advantage of limestone used in converter steel- making has been explained. The substitution of lime for limestone in slag- making process has reduced the blowing temperature in the early process of converting,and increased the mixing power of the steel slag,which has lowered the cost of converter steel- making and achieved great economic profits.
Keywords: limestone; converter
