1.概况1992年6月11日,新疆钢铁公司八钢炼铁厂1号高炉大修改扩工程胜利竣工。从停风拆炉到送风生产只用了71天。高炉投产两个多月以来,主体设备运转正常,炉况顺行,产量不断提高,高炉利用系数8月份达1.776,提前两个月达产。1号高炉此次大修,炉容由255m~3扩至350m~3,其设计能力年产20～23万吨生铁。新高炉采用自立式框架结构、薄炉墙、“Г”型镶砖冷却壁、自焙炭砖高铝砖综合水冷炉底、新型三腔双环流风渣口等新工艺、新设备,且自动化程度较高。改造项目主要集中在高炉主体,其四周均被高架料仓、2号高
1. Overview June 11, 1992, Xinjiang Iron and Steel Company eight steelworks No. 1 blast furnace overhaul expansion project completed. Stall from oven to blast production only took 71 days. Since the blast furnace was put into operation for more than two months, the main equipment has been operating normally and the furnace has been operating smoothly. The output has been continuously raised. The blast furnace utilization factor reached 1.776 in August, reaching the production capacity in two months in advance. Blast furnace No. 1 overhaul, furnace capacity by 255m ~ 3 expanded to 350m ~ 3, its design capacity of 20 to 230,000 tons annual output of pig iron. The new blast furnace adopts self-supporting frame structure, thin furnace wall, “Г” type mosaic tile cooling wall, self-baking charcoal brick high alumina brick comprehensive water-cooled hearth, new three cavity dual circulation flow slag mouth and other new technology and new equipment, Higher. Reconstruction projects are mainly concentrated in the main blast furnace, surrounded by elevated silos, No. 2 high
