我公司第二炼钢厂,于1976年从日本新日铁引进了KR搅拌式脱硫装备。该专利规定以CaC_2作为脱硫剂。实践证明,采用CaC_2脱硫剂,虽然脱硫效果良好,能将铁水含硫量降低到0.005％以下,但CaC_2的加工、运输、贮存和价格均存在问题,使用起来也不安全。因此,研制一种既能保证达到专利要求,又经济安全的新型脱硫剂,成为KR脱硫生产中急需解决的重要课题。二炼钢和钢研所合作,研制的以活性石灰为主的三种复合脱硫剂(KC-1、KC-2、KC-3),经试验,效果良好。在此基础上于1986年1～8月选其中综合效果好的KC-1进行了375罐次的试生产,结果表明,新型
My company’s second steel mill, in 1976 from Japan’s Nippon Steel introduced KR mixing desulfurization equipment. The patent provides CaC_2 as a desulfurizer. Practice has proved that the use of CaC_2 desulfurization agent, although the desulfurization effect is good, can reduce the sulfur content of molten iron below 0.005%, but CaC_2 processing, transportation, storage and price problems, it is not safe to use. Therefore, developing a new type of desulfurizer that can not only ensure the patent requirement but also be economical and safe has become an urgent issue to be solved urgently in the KR desulfurization production. Two steel and steel research institutes, developed by active lime-based three kinds of composite desulfurizer (KC-1, KC-2, KC-3), the test, the effect is good. On this basis, from January to August 1986, KC-1, which had a good comprehensive effect, was selected for trial production of 375 cans. The results showed that the new type
