Abstract

It is well known that center segregation of continuous casting steel is muchimproved by low superheat casting. However, the low superheat casting is not utilized because of the problem of nozzle clogging. The techniques of electromagnetic stirring and reduction technique have been employed to improve the segregation even under the high superheat casting. In these methods. a large amount of equiaxed crystals is favorable to maintain the internal quality. Therefore, Iow superheat casting methodby a new type nozzle with air cooling and electromagnetic stirring was devised and teeming experiment using 500kg or 3t molten steel was carried out to investigate the cooling ability of the nozzle.
