Method for Producing a Mold Tube

Abstract

A method for producing a mold tube from copper or a copper alloy for a continuous casting mold, a tube blank being formed on a mandrel, which determines the inner shape of the mold, by the external application of force, and, following the shaping process, the mandrel being removed from the mold tube ( 1, 1 a ); the action of force resulting in response to the movement of the tube blank relative to the die surrounding the same; the die having a shaping structure for a cold formed profile ( 6, 6 a; 7, 7 a ) on the outer surface ( 5 ) of the mold tube ( 1, 1 a ), so that the cold formed profile ( 6, 6 a; 7, 7 a ) is produced by the die upon shaping of the tube blank on the mandrel.

         9 . A method for producing a mold tube from copper or a copper alloy for a continuous casting mold, comprising: forming a tube blank on a mandrel, which determines an inner shape of the mold, by externally applying force; and following shaping, removing the mandrel from the mold tube ( 1 ,  1   a ), the action of force resulting in response to movement of the tube blank relative to a die surrounding the same, wherein the die has a shaping structure for a cold formed profile ( 6 ,  6   a;    7 ,  7   a ) on an outer surface ( 5 ) of the mold tube ( 1 ,  1   a ), so that the cold formed profile ( 6 ,  6   a;    7 ,  7   a ) is produced by the die upon shaping of the tube blank on the mandrel. 
     
     
         10 . The method as recited in  claim 9 , wherein the cold formed profile ( 6 ,  6   a;    7 ,  7   a ) is produced in response to the pulling of the tube blank through the die. 
     
     
         11 . The method as recited in  claim 9  wherein the corner regions ( 2 ) of the mold tube ( 1 ,  1   a ) are excluded from the production of the cold formed profile ( 6 ,  6   a;    7 ,  7   a ). 
     
     
         12 . The method as recited in  claim 10  wherein the corner regions ( 2 ) of the mold tube ( 1 ,  1   a ) are excluded from the production of the cold formed profile ( 6 ,  6   a;    7 ,  7   a ).
