一、炼铁1986年生产情况1.生产发展1986年是我国炼铁生产飞跃发展的一年。全年生铁产量达5008万吨,比1985年增加648万吨,超过了“六五”期间五年的增产量(558万吨),基本扭转了钢铁生产平衡中生铁不足的局面。生铁的增产,除宝钢216万吨和少数地方厂新建高炉所增加的产量外,绝大部分为老厂挖潜所得,其中重点企业挖潜增产144万吨。重点企业高炉平均利用系数第一次突
First, the production of iron in 1986 1. Production Development 1986 is the rapid development of China’s iron production year. The annual output of pig iron reached 50.08 million tons, an increase of 6.48 million tons over 1985, surpassing the five-year increase (5.58 million tons) during the “6-5” period and basically reversing the shortage of pig iron in the balance of steel production. Pig iron production, in addition to 2.160 million tons of Baosteel and a few local furnaces increased production of new blast furnace, the vast majority of the potential benefits of the old plant, in which the key enterprises to tap the potential increase of 1.44 million tons. The average blast furnace utilization factor of the first sudden
