酒钢1号高炉于1990年3月12日7点40分出完铁,该炉铁的含硅量为1.75%,含硫0.013%。17分钟后,高炉没有低压,也没有休风,在正常的生产情况下发生了崩塌事故。炉体从炉腰托圈以上、卷扬斜桥、炉顶煤气上升管、下降管和4根大支柱全部倒塌,除尘器旁的倒流休风管也同时倒了下来。除尘器及1号热风炉经测定均有向西倾斜现象。高炉系处于大修前期,炉体破损较为严重,当时有五段26号冷却壁漏水,还有3个 Jiuquan Iron & Steel No. 1 blast furnace at 7:40 on March 12, 1990 finished the iron, the iron content of 1.75% silicon, 0.013% sulfur. After 17 minutes, there was no low pressure in the blast furnace and there was no break, and a collapse occurred under normal production conditions. Furnace from the waist ring above the hoisting bridge, furnace top gas riser, down pipe and four large collapsible collapses, dust collector next to the flow of the down tube also fell down. Precipitator and No. 1 stove have been measured to the west tilt phenomenon. Department of blast furnace overhaul in the early, more serious damage to the furnace, there were five sections of the cooling wall leakage on the 26th, there are 3
