1 60年代在工业发达国家新增设小方坯连铸机最初(1920～1930年),连铸机被实用于连铸Cu、Al等合金。由于钢铁比非铁金属的熔化温度高热传导率低等原因,实现连铸非常困难。但是,其后以欧洲为中心的各国致力于以钢铁为对象的连铸机的研究开发。进入50年代以原西德为首,以及奥地利、英国、苏联等相继达到了实用化。其结果,60年代末在15个国家内共设置连铸机31座,年生产能力达到约130万t。但是,当时在这些国家设置的连铸设备,基本上是生产能力小于10万t的小型设备。此外,连铸钢
In the 1960s, a new billet caster was newly added in industrialized countries (1920 ~ 1930). The continuous casting machine was used to continuously cast Cu, Al and other alloys. Because steel has a lower thermal conductivity than the melting temperature of non-ferrous metals, it is very difficult to achieve continuous casting. However, the countries that followed Europe as a whole are committed to the research and development of continuous casting machines for steel. In the 1950s, the former West Germany led, as well as Austria, Britain, the Soviet Union, have reached the practical. As a result, a total of 31 continuous casting machines were installed in 15 countries in the late 1960s and the annual production capacity reached about 1.3 million tons. However, the continuous casting equipment set up in these countries at the time was basically a small piece of equipment with a production capacity of less than 100,000 t. In addition, continuous casting steel
