真空提升法处理钢水是五十年代冶金技术的新发展。从西德多特蒙特公司在1955年建立第一台设备以来到1962年年末世界主要资本主义国家——美、英、日、西德、加拿大等国,共已有十三台设备投入了工业性生产,现已被公认为大规模真空处理钢水最有效的方法之一。目前最多能处理200吨钢水(美国坩埚钢公司的160吨设备设计为200吨)。据报导,美国目
Vacuum lifting method to treat molten steel is a new development of metallurgical technology in the 1950s. From the establishment of Dortmund West Germany in 1955 the first equipment since the end of 1962 the world’s major capitalist countries - the United States, Britain, Japan, West Germany, Canada and other countries, a total of 13 devices have been put into the industry Sexual production is now recognized as one of the most effective ways to treat molten steel on a large scale in vacuum. Up to 200 tons of molten steel can currently be processed (160 tons of US crucible steel company designed to 200 tons). It is reported that the United States head
