The earliest horizontal continuous casting steel is the United States General Motors, in 1969 with three stream machine to produce φ100mm round billet, and in 1971 the first level of continuous casting of steel used in industrial production. 1976 British David and Japan Steel Pipe Company to develop a total of the country, set up a student in Fukuyama, Japan
