马鞍山钢铁股份有限公司第四炼铁厂于1995年5月16日成立,现有2座2500m~3高炉,其中在建的新2号高炉拟于2003年11月投产。另外,还新建1座850m~3高炉,预计于2004年4月投产。届时,将形成年产生铁500万 t 的生产规模。新1号高炉(2500m~3)于1987年10月18日奠基,1994年4月25日投产,至今已生产9年。回顾这9年来的历程,大体上可分为以下三个阶段:一是艰难的起步阶段。这一阶段,大约历时3年多。新1号高炉投产以后,由于系统不配套,设备缺陷多,加上人员新以及缺乏大型高炉操作经验,造成故障频发,炉况波动大,严重影 The Fourth Iron Works of Maanshan Iron & Steel Co., Ltd. was established on May 16, 1995. It has 2 2500m ~ 3 blast furnaces and the new No. 2 blast furnace under construction is about to be put into operation in November 2003. In addition, a new 850m ~ 3 blast furnace is also planned to be put into operation in April 2004. By then, will produce an annual output of 5 million tons of iron production scale. The new No. 1 blast furnace (2500m ~ 3) was laid on October 18, 1987 and was put into operation on April 25, 1994 and has been produced for 9 years.
