在经过几十年的不断改进、发展和完善之后 ,国外连铸生产技术、设备等已达到很高的水平 ,其主要特点为 :(1 )常规连铸生产已趋成熟目前国外连铸机的作业率普遍大于 90 % ,大型板坯连铸机连铸约 1 0 0～ 2 0 0万 t钢才漏钢一次 ,已基本可生产无缺陷铸坯 (包括合金钢 )。而我国连 After decades of continuous improvement, development and improvement, foreign continuous casting production technology and equipment have reached a very high level. The main features are as follows: (1) Conventional continuous casting production has matured At present, foreign continuous casting machine Operating rate is generally greater than 90%, large slab caster continuous casting of about 1 0 0 ~ 20 million tons of steel before breaking once, the basic production of non-defective slab (including alloy steel).
