Production Facilities and Operational Techniques for Continuous Forging Process

Hajime Bada, Fumio Sudo, Toshitane Matsukawa
Synopsis :
To solve the problem of segregation in continuous casting, the continuous forging process was developed and installed at No.3 Continuous Caster of Mizushima Works as the first facility of its kind in the world. The process has been successfully applied in commercial operation to the production of high quality CC blooms with no centerline segregation or negative centerline segregation. Special care was taken in designing a process for a multi-strand caster to simplify the facility and reduce the investment cost by adopting a crankshaft system driven by a single motor. The degree of centerline segregation can also be controlled within the range of negative to positive, depending on customer requirements, by choosing an appropriate solid fraction during forging.
