武钢第二炼钢厂是70年代末建成投产的。三座50t纯氧顶吹转炉的年生产能力为150万吨;与之相匹配的是三台从西德引进的单流弧形板坯铸机,弧形半径为10.3m,年产连铸板坯120万吨(连铸比80％),模铸锭30万吨。连铸和模铸工艺相比,其突出的优势在于有较高的金属收得率,从而带来明显的经济效益。因此,提高连铸比,实现全连铸几乎是每一个拥有连铸设备的炼钢厂所追求的共同目标。早在1983年,该厂就曾拟议了一个
Wuhan Iron and Steel No. 2 Steel Plant was put into operation in the late 70s. Three 50t pure oxygen top blown converter annual production capacity of 1.5 million tons; match with the three from the introduction of the West Germany single-flow arc-shaped slab casting machine, arc radius of 10.3m, with an annual output of continuous casting 1.2 million tons of slab (continuous casting ratio of 80%), 300,000 tons of ingots. The outstanding advantages of continuous casting and die casting are the higher metal yield and the obvious economic benefits. Therefore, increasing the continuous casting ratio and achieving full continuous casting are the common goals pursued by almost every steel mill that owns the continuous casting equipment. As early as 1983, the plant had proposed one
