一、前言为了满足市场上对纯净钢的需求,开发了铁水预处理和钢水二次精炼工艺并将其应用于实际。中华钢铁公司于1982年1月完成了第二期工程建设后,为了提高钢的质量,使一座在鱼雷式混铁车内脱硫的铁水脱硫站、RH真空脱气装置、铝线投射机及钢包喷吹站等几种钢水精炼设备投入了生产。通过喷枪喷吹以CaC_2为主的熔剂能使铁水含硫量降低到约0.010％。此外,由于在氧气转炉烁钢之后应用了钢包喷吹法,使超低硫钢
First, the foreword In order to meet the market demand for pure steel, the development of hot metal pretreatment and secondary refining of molten steel and its application in practice. After the completion of the second phase of construction by China Steel Corporation in January 1982, in order to improve the quality of steel, a hot metal desulphurization station, a RH vacuum degassing unit, an aluminum wire projector and a ladle Injection station and several other molten steel refining equipment into production. Spraying CaC_2-based flux through the spray gun can reduce the sulfur content of molten iron to about 0.010%. In addition, the use of the ladle blow method after the oxygen converter shimmering makes the ultra-low sulfur steel
