鞍钢第三炼钢厂是50年代末建成的大型平炉炼钢厂,建有固定式370t平炉三座,500t平炉两座,设计年产钢量为140万吨。 70年代初,公司开始着手对这一平炉钢厂进行技术改造,改造规划分两期实施,第一期预定将原有平炉改造为顶吹氧气转炉,第二期增建板坯连铸机。至1984年底,建成了容量为150t转炉两座和180t转炉一座,拆除了原有五座平炉,增建了铁水预处理、钢水罐喷吹设施,引进了国外炼钢自动控制设
The third steel mill in Ansteel is a large open hearth steelmaking plant built in the late 1950s. It has built three fixed 370t open hearth furnaces and two 500t open hearth furnaces. The designed annual steel production capacity is 1.4 million tons. In the early 1970s, the company started to carry out technical transformation of this open hearth steelmaking plant. The renovation plan was implemented in two phases. The first phase of the plan was to transform the existing open hearth into a top-blowing oxygen converter and the second phase to build a slab continuous casting machine. By the end of 1984, built a capacity of 150t converter two and 180t converter a demolition of the original five open hearth furnace, additional hot metal pretreatment, ladle injection facilities, the introduction of foreign steelmaking automatic control set
