1.概况天津铁厂1号高炉于1984年建成,1986年12月18日投产。1990年以前,用小风机冶炼,顺行良好,没有大的破损记录。1990年开始,改用风量为2000m~3/min的大风机冶炼,长期边缘气流过分发展,并造成炉衬侵蚀,冷却设备大量烧坏。1990年12月23日休风后,发现炉身下部冷却板已完全裸露;五、六段镶砖冷却壁损坏达54.17%,冷却板损坏达46.93%,支梁水箱损坏44.44%。1995年7月,炉龄八年半的1号高炉炉体破损更加严重,五、六段镶砖冷却壁损坏
1. Overview Tianjin Iron Works No. 1 blast furnace was completed in 1984, December 18, 1986 put into production. Before 1990, with a small fan smelting, go well, no major damage records. Beginning in 1990, switch to the use of large fan blower 2000m ~ 3 / min, long-term marginal flow over-development, and led to the lining erosion, a large number of cooling equipment burnout. After the wind off on December 23, 1990, it was found that the cooling plate at the lower part of the furnace body was completely exposed. The damaged walls of the fifth and sixth paragraphs reached 54.17%, the cooling plate damaged by 46.93% and the damaged water tank by 44.44%. In July 1995, furnace No. 1 for eight and a half years was more damaged by the blast furnace body, and the damaged walls of the fifth and sixth sections were damaged
