Abstract

PURPOSE:To prevent degradation in quality owing to the dent of both ends on long side of a cast ingot and improve productivity by forming the shape of the molten steel contact surface of the short side of a mold for casting ingot into an arc-shaped concave shape of a limited radius. CONSTITUTION:The basic shape of the molten steel contact surface of the horizontal section of the sides (short sides) 2 of a mold is beforehand made an arc-shaped concave shape 9 of a radius R 0.8-2 times the thickness of an ingot by predicting the bulging of the short sides of the ingot. With such mold, the short sides 2 of the ingot are of a stable shape from the initial period of casting and there is no formation of any dent on both ends of the horizontal sides (long sides) 1. Hence, the flow of cooling water in dents and the occurrence of a temperature difference are obviated. The reason for limiting the arc-shape radius R of the concave face 9 is, if the radius R is made small, the position of cooling channels 10 position further from the inside wall of the mold and this results in the decreased cooling capacity of both ends (a) of the short sides; in addition, this causes wear in both ends (a).
