众所周知，随着钢材质量优化要求钢水含流越低越好，但是在炼钢过程中要进行有效的脱[S]，未必容易高炉内铁水有良好的脱[S]条件，但是要依靠增加渣量、提高铁水温度和调整炉渣成份来进行脱[S]，脱[S]率一般只达到90％土。为了满足炼钢对铁水含[S]的严格要求，大约有80％的高炉 As we all know, with the steel quality requirements of the lower the better the flow of molten steel, but in the steelmaking process to be effective off [S], not necessarily easy to blast furnace hot metal off [S] conditions, but to increase slag The amount of hot metal to improve the temperature and adjust the slag composition to take off [S], off [S] rate is generally only 90% of the soil. In order to meet the stringent requirements of [S] for hot metal in steel-making, about 80% of the blast furnace
