GRAPHITE MOLD FOR VERTICAL TYPE CONTINUOUS CASTING

摘要

PROBLEM TO BE SOLVED: To provide a graphite mold for continuous casting, wherein the structure is simple and a heat conductivity from the graphite cylindrical body to a cooling jacket in the drawing-out direction of a cast block can be adjusted and a Sump-shape in the cast block in the mold can be controlled.;SOLUTION: The graphite mold 10 for vertical type continuous casting for copper and copper alloy, has the cooling jacket 11 composed of a heat-conductive material and formed into a cylindrical-shape, and the graphite cylindrical body 21 arranged in the inner peripheral surface of the cooling jacket 11, wherein the one opening hole part of the graphite cylindrical body 21 serves as a molten metal pouring portion for pouring molten copper and the other opening hole part serves as a cast block producing-outlet for producing the cast block, and grooves 22 extended to the axial line direction of the graphite cylindrical body 21 are formed between the cooling jacket 11 and the graphite cylindrical body 21, and the grooves 22 allows the heat conductivity from the graphite cylindrical body 21 to the cooling jacket 11 at the molten metal pouring hole side to be made smaller than the heat conductivity at the cast block producing-outlet side.;COPYRIGHT: (C)2007,JPO&INPIT
