炉料结构是否合理,直接影响着高炉冶炼焦比和其它技术经济指标,这个问题已日益被炼铁工作者所重视。目前,各国高炉炉料结构基本上有如下五种:(1)、100%的酸性球团(每吨生铁加200公斤左右石灰石);(2)、80%的酸性
Whether the charging structure is reasonable and directly affects the smelting coke ratio of blast furnace and other technical and economic indicators has been paid more and more attention to by iron-smelting workers. At present, there are basically the following five kinds of blast furnace charge structures in different countries: (1) 100% acid pellets (about 200 kilograms of limestone per ton of pig iron), (2) 80% acidity
