1 概况柳钢炼铁厂3号高炉自1988年建成投产以来,炉壳都没有进行过维修。1998年,标高为18.3m至23.3m之间的支梁水箱及砖衬结构严重漏水、脱落,炉壳只剩下一层钢板,使得炉体发红、变形。为防止烧毁炉壳,只能在炉壳外洒水降温,这势必导致热量散失,影响顺行。正常日产量达900多吨的高炉只能产400～600吨! 经综合研究,我厂决定从支梁水箱到炉喉钢砖之间采用冷却模块来代替原来的支梁水箱及砖衬结构。并在2000年12月30日至2001年元月6日年修时由修建公司负责安装。
1 Overview Liuzhou Iron and Steel No. 3 blast furnace since its completion in 1988 put into operation, the furnace shell has not been repaired. In 1998, the height of 18.3m to 23.3m between the support beam tank and brick lining serious water leakage, falling, the furnace shell is only a layer of steel, making the furnace redness, deformation. In order to prevent burned furnace shell, can only sprinkle water cooling outside the furnace shell, which will inevitably lead to heat loss, affecting the antecedents. The normal daily output of more than 900 tons of blast furnace can only produce 400 to 600 tons! After comprehensive study, I decided to plant from the support beam to the throat steel brick cooling module used to replace the original support beam tank and brick lining structure. And in the December 30, 2000 to January 6, 2001 annual repair by the construction company responsible for the installation.
