为了搞好焦炭的综合利用,近几年来,我厂在50m~3高炉上对搭配焦丁入炉的工作进行了多次试验。1985年曾采用改变料批组成的方法,即每10批正常料加一批焦丁(2料车,重450kg)。由于焦丁集中在一处,炉内煤气通路被焦丁堵死,结果造成炉况不顺,经常出现难行、悬料现象,因此中断了试验。从今年(1987年)3月18日起,采取在矿石中搭配焦丁入炉,经过3个多月的生产 In order to improve the comprehensive utilization of coke in recent years, I plant in the 50m ~ 3 blast furnace with coke into the furnace work carried out several tests. In 1985, the method of changing material batch was used, that is, a batch of coke Ding (2 cars and weighing 450kg) was added for every 10 normal lots. As Jiao Ding concentrated in one, the furnace gas path was Jiao Ding blocked, resulting in furnace conditions are not smooth, often difficult to hang, suspended phenomenon, so interrupted the test. From this year (1987) on March 18, taken in the ore coke into the furnace, after more than three months of production
