Recent Development of Research on Soft-contact Electromagnetic Continuous Casting of Japan

The principle of soft-contact electromagnetic continuous casting and the recent research development in Japanese were introduced.The influence of coil current,Joule heat,the shape of the mold and the early-solidified shell on surface quality of strand was discussed.The problems that should be noticed in future were presented.The following views are concluded.The Joule heat produced by induction coil is the chief influence factor of strand surface quality.There is an optimum coil current,otherwise,it would have unfavorable effect on the surface quality of strand.With same technological parameters,the surface quality of strand produced by round angle mould is better than by right angle mould.
