目前在国外连续浇注板坯有了很大的进展,从西德和苏联等一些国家所取得的经验说明:浇注宽800毫米以上的板坯不会有太大的困难。根据文献资料的统计,能够生产宽板坯的国家有苏联、西德和日本,而英国与西德某些工厂还处在建设这种装置的阶段(见表1)。苏联斯大林诺冶金工厂的四流连续铸钢机是目前世界上最大的一台装置,它的总高是27米,建在深24米的地坑中,生产能力3～4万吨/月。西德底林根冶金工厂于1959年底设计了一台单流立弯式试验装置,1962年2月28日投入生产。主要浇注1000×200毫米~2及1500×200毫米~2板坯,供给SOLLAC宽带钢轧机轧成各种钢板。装 The continuous casting of slabs in foreign countries has made great progress. The experience gained from some countries such as West Germany and the Soviet Union shows that casting slabs wider than 800 mm does not have much difficulty. According to the literature, the countries that can produce wide slabs include the Soviet Union, West Germany and Japan, while some plants in Britain and West Germany are still in the process of constructing such devices (Table 1). The four-strand continuous casting machine at the Metallurgical Plant in the Stalinist Soviet Union is the largest one in the world with a total height of 27 meters. It is built in a 24-meter deep pit with a production capacity of 30,000 to 40,000 tons per month. At the end of 1959, the West Germany Diehl Metallurgical Plant designed a single-flow vertical bending test device which was put into production on February 28, 1962. The main casting 1000 × 200 mm ~ 2 and 1500 × 200 mm ~ 2 slabs, for the SOLLAC wide strip mill rolling into a variety of steel. Loaded
