一、国内转炉复吹发展概况自1983年8月在首钢召开转炉顶底复合吹炼第一次经验交流会议之后,近两年来又有新的进展。1984年重点企业11个炼钢厂,复吹转炉产钢377万吨,占其氧气转炉钢总产量的24％。 1.上马快、效果好据不完全统计,目前已有16个厂、27座复合吹炼氧气转炉,见表1。 First, the domestic development overview of BOF blowing Since August 1983 in Shougang held the first BOF blowing exchange experience meeting, in the past two years and new progress. In 1984, 11 steel mills of key enterprises and 3.37 million tons of steel produced by the compound blow converter accounted for 24% of the total output of oxygen converter steel. 1. Quickly launched, the effect is good According to incomplete statistics, there are currently 16 plants, 27 composite oxygen blowing furnace, see Table 1.
