一、前言中国连续铸锭起步较早,50年代中期便开始进行探索性试验。1960年前分别在上海、重庆、唐山建成三台立式连铸机。1964年在重庆钢铁公司三厂正式建成弧形板坯连铸机。以后陆续在上海几个钢厂以及天津、首钢等厂建成一批连铸机,到1964年止我国已有20个钢厂拥有42台连铸机。 1980年以后,我国连铸生产得到进一步发展。1984年共生产连铸坯460万吨,比1980年的230万吨增加一倍,连铸比达到10.6%。最近四年内(1980～1984)新建成14台连铸
I. Introduction China’s continuous ingot started earlier, and began exploratory experiments in the mid-1950s. Before 1960, respectively, in Shanghai, Chongqing, Tangshan built three vertical caster. 1964 in Chongqing Iron and Steel Company three plants formally built arc slab caster. Later in succession in Shanghai several mills and Tianjin, Shougang and other plants built a number of caster, by 1964 China has 20 mills have 42 caster. After 1980, China’s continuous casting production has been further developed. In 1984, a total of 4.6 million tons of slabs were produced, doubling the 2.3 million tons in 1980 and the continuous casting ratio reached 10.6%. In the last four years (1980 ~ 1984), 14 new continuous casting machines were completed
