TH40829B - Method for producing sheet metal strips - Google Patents

Abstract

DC60 (10/10/46) This invention relates to a method for producing sheet metal strips from cast metal by rolling where In this method, the technique of edge-forming in combination with strip-rolling is used. The material for the strip-plate is first cast by using the casting technique to produce the edge-forming of the strip. A cast metal with a thicker center than the lateral parts and shaped edges of the cast metal is introduced into the Approximately continuous ironing machine where during at least two steps of edge rolling The rims of the cast metal are divided into two symmetrical halves and are maintained as two equal halves. These halves are radiated into the lateral regions of the material to be rolled to form a rim. Flattening, which is the object for strip rolling at least one step so that the radiating ratio Between the dimensional dimensions of the center part of the cast metal rim and the width of the strip plate greater than 2.8 1 were achieved. This invention relates to a method for producing metal strips from cast metal by rolling where In this method, the technique of edge rolling in combination with strip rolling is used. The material for the strip strip is first cast by using the slab casting technique to produce the edge profile of the A cast metal with a thicker center than the lateral parts and shaped edges of the cast metal is introduced into the Approximately continuous ironing machine where during at least two steps of edge rolling The edges of the cast metal are bent into two equal segments and are maintained into two equal segments. These segments are radiated into the lateral regions of the material to be rolled into a shape. edge at Flattening, which is the object for strip rolling at least one step so that the radiating ratio Between the dimensional dimensions of the center part of the rim of the cast metal and the width of the strip plate greater than 2.8 : 1 are achieved:
