高炉入炉物料的筛分对高炉顺行有重要意义。首钢炼铁厂在试验的基础上 ,对高炉槽下烧结矿、生矿、球团矿及焦炭筛分系统进行了改造 ,使其筛分效率均达到 90 %以上 ,高炉入炉粉矿及碎焦含量连续 3年保持在 5 %以下 ,促进了高炉的顺行和利用系数的提高
Blast furnace into the furnace material screening on the blast order is of great significance. On the basis of the experiment, Shougang Iron & Steel Co., Ltd. reformed the sinter, raw ore, pellet and coke screening system under the blast furnace tank so that the screening efficiency reached above 90%. The blast furnace slag powder and crushed The coke content kept below 5% for 3 years in a row, which promoted the improvement of blast furnace’s direct and utilization coefficient
