COOLING WATER CHANNEL STRUCTURE OF SHEET CONTINUOUS CASTING ROLL

摘要

The present invention relates to the structure of the cooling water passage of the continuous sheet casting roll, more specifically, by configuring the passage so that the cooling water flows symmetrically with respect to the center of the casting roll to improve the quality of the thin plate casting by uniformly cooling water temperature distribution, The present invention relates to a cooling water passage structure of an improved thin continuous casting roll to achieve a stable casting operation.;The present invention is a thin plate continuous casting facility for continuously manufacturing a thin plate by injecting molten metal between a pair of casting rolls, the inner tube of the double pipe structure extending from one side end of the casting roll to the inner center, and the appearance The inner pipe forms a cooling water supply pipe and extends from the inner side of the casting roll to the center portion and is connected to a plurality of radially extending branch pipes, the branch pipes are connected to the surface passages, and the surface passages are formed on side passages formed on both sides of the casting rolls. On the other hand, the side passages are connected to the outer constituting the cooling water discharge pipe on both sides of the casting roll to provide a cooling water passage structure of the thin continuous casting roll is formed in a uniform temperature distribution in the width direction with respect to the center of the casting roll. On the other hand, in the cooling water passage structure, the external appearance may be a cooling water supply pipe, and the large pipe may be a cooling water discharge pipe.
