为了改善焦炭热态指标,降低焦比及炼铁成本,对焦炭钝化剂采购引入竞争机制,在580m3高炉所用的焦炭上进行了喷洒钝化剂工业生产对比试验。1工业生产试验安排10月3日以前580m3高炉焦炭喷洒第一家钝化剂;10月4日8:00时开始第一家焦炭钝化
In order to improve the coke thermal index, reduce the coke ration and the cost of ironmaking, a competition mechanism was introduced into the procurement of coke passivator. The comparative test of industrial production of passivation agent was carried out on coke used in 580m3 blast furnace. 1 industrial production test arrangements before October 3 580m3 blast furnace coke spray the first passivation; at 8:00 on October 4 when the first coke passivation
