苏联煤铁资源丰富,发展钢铁工业物质基础雄厚,年产量100万吨以上的钢铁厂就有20家,1985年生产生铁1.1亿吨.近年来高炉采用了大量强化措施,生产指标不断改进,引人注目的有高炉使用金属化炉料,其工业性试验已经完成.在控制冷却强度,探求最佳矿相成分旨在提高烧结矿强度的研究也有进展.在炉缸工作状态的研究方法上取得了新的突破.以高富氧率配合天然气大喷吹量为特征的综合鼓风是苏联炼铁工艺独特之处,对改善生产指标起了重大作用.对常规的布料方法苏联也作了较为深入的研究并获得了良好的效果,收到了明显的经济效益.
The Soviet Union is rich in coal and iron resources and has a strong material foundation for the development of the iron and steel industry. There are 20 steel mills producing more than 1 million tons of steel and 110 million tons of pig iron in 1985. In recent years, the blast furnace has adopted a large number of intensified measures to continuously improve its production targets. The focus of the use of blast furnace metal charge, the industrial test has been completed in the control of cooling intensity, to explore the best phase composition of the ore to improve the strength of sinter research has also made progress in the study of the working conditions of the hearth made The new breakthrough.The combination of high blowing rate and high oxygen enrichment rate with the large amount of natural gas blowing is the unique feature of the Soviet Union ironmaking process, to improve the production index played a significant role.For the conventional method of cloth the Soviet Union also made a more in-depth Research and get good results, received significant economic benefits.
