却说铆焊车间经过3个月的苦战,已突击加工制作出一座超大型高炉炉壳,容积为3200m~3,系全国第2大现代化高炉主体工程。冶炼设备从美国、日本、卢森堡等8个国家引进。金属结构厂为节约外汇,主动承接了制作高炉炉壳的任务,眼下却遇到攻克水冷管孔这一难关。高炉炉壳似一个庞然大物矗立在车间,足有排球场大,沿炉壳周边需钻120个直径为120mm的水冷管孔。采用
But said that after three months of hard work in the welding workshop, an extremely large blast furnace shell has been assaulted and processed, with a volume of 3200m ~ 3, which is the second major modern blast furnace in China. Smelting equipment from the United States, Japan, Luxembourg and other eight countries to introduce. Metal structure plant in order to save foreign exchange, take the initiative to undertake the task of making blast furnace shell, now they have to overcome the difficulties of water cooling pipe holes. Blast furnace shell like a monolith stands in the workshop, enough volleyball court large, around the furnace shell to be drilled 120 120mm diameter water-cooled pipe holes. use
