最近石钢、本钢炼铁厂的职工在活学活用主席著作,更好为用户服务思想的指引下,为了改善铸造生铁质量,精益求精,减少同一炉次不同罐号的生铁成分波动,采取了双罐同时放铁的措施。即将原来一个罐一个罐顺序地放铁改为两个罐同时放铁,使每炉生铁的初、中、后期生铁成分得到充分混匀作用。根据本钢的试验,在未改双罐同时放铁时,每个炉次生铁第一罐与第二罐硅平均差为0.173%,最大差值为0.59%(石钢最大差值为0.64%);硫平均差值为0.006%,因此,影响上升铁号的占61%,下降铁号的占39%;硫差值影响上升类的占48%,下降类的占52%,过去用户对此曾提出较多意见。
Recently, the employees of Shigang and Benxi Iron & Steel (Group) Co., Ltd., under the guidance of their chairmanship and better customer service philosophy, have tried their best to improve the quality of foundry pig iron, keep improving and reduce the fluctuation of pig iron composition in different tanks of the same heat. Double-tank at the same time the iron measures. About the original one tank of a tank of iron to the two tanks at the same time put the iron, so that each pig iron furnace early, middle and late pig iron components are fully mixed effect. According to the test of this steel, the average difference between the first and second cans of each pig iron was 0.173% and the maximum difference was 0.59% (the maximum difference of the stone steel was 0.64% ); Sulfur average difference of 0.006%, therefore, affect the rising iron number accounted for 61%, down iron number accounted for 39%; sulfur difference affects the rising class accounted for 48%, falling class accounted for 52% of the past users This has made more comments.
