ABSTRACT:
This invention relates to the method and apparatus for improving the cast ingot, cast in a continuous casting equipment which is commonly called a "belt-and-wheel" system wherein a casting wheel and a metallic belt are employed, by applying a light reduction to the cast ingot to give elongation under compressive stress during the process wherein the curvature of the cast ingot changes as the cast ingot travels from the exit of a casting wheel.
More particularly, this invention relates to cast ingot quality improvement method and apparatus in a continuous casting which aims at preventing cracks which were liable to occur on the groove bottom side of the ingot cast by the said continuous process; similarly it also aims at crushing blow holes which tended to concentrate on the groove bottom side the cast ingot.
