GUIDE ROLL OF CONTINUOUS CASTING MANUFACTURED BY DOUBLE CENTRIFUGAL CASTING PROCESS OF LIQUID PLUS LIQUID, AND TRANSPORTATION TRANS ROLL USING THE SAME

摘要

The present invention relates to a performance guide roll and the transfer roll using the same transformer that is produced by using a double centrifugal casting as, more particularly, the purpose of pre-heating step and the centrifugal mold to improve the durability of the performance guide roller for guiding the slab in the continuous casting machine of the playing process of steel production process, the coating applied to the internal centrifugal process and mold, the centrifugal molds some of the molten outer layer and a metal injection molding process for the rotation, the outer temperature check step and the layer, and an inner layer forming step which is located in the outer layer, the inner surface by injecting a predetermined molten metal, temperature checking step and the cooling of the inner layer / heat treatment sequentially performance guide roll produced by using a double centrifugal casting process and transferred to the transport roll hayeoseo chakseol a bearing on the shaft hole is started.
