Title:
同じまたは類似の収縮係数を有する金属の連続鋳造
Document Type and Number:
Japanese Patent JP5432146
Kind Code:
B2
Abstract:
A method and apparatus is disclosed for casting metals in a DC mold to form an ingot or product having at least two layers formed by sequential solidification. The apparatus has at least one cooled divider wall at the entry end portion of the mold to divide the entry end portion into at least two feed chambers. Metal is fed to the chambers to form an inner layer and at least one outer layer. The divider wall has a metal-contacting surface for contacting the metal for the at least one outer layer, the surface being arranged at an angle sloping away from the metal for the outer layer in a downward direction. The angle is larger at the center of the divider wall compared to the angle adjacent to each longitudinal end thereof. The apparatus is suitable for co-casting metals having similar coefficients of contraction to minimize problems of adhesion between the layers of a resulting ingot or rolled products produced therefrom.
