Abstract
A casting method and apparatus making use of a twin belt caster which has an upper belt, a lower belt and dam members disposed between both opposing longitudinal edges of the upper and lower belts. The upper belt, lower belt and dam members in cooperation provide a continuous casting mold which is inclined at a predetermined angle from the horizontal plane and into which a melt of steel is poured. The lower belt provides a smaller cooling effect than the upper belt so that the solidification of the melt is retarded in the region near the lower belt as compared with the region near the upper belt.
