Method for Producing Metal Sheets from a Magnesium Melt

Abstract

A method for producing metal sheets from a magnesium melt, comprises the following steps: producing the magnesium melt, casting the magnesium melt to a cast strip, immediately after casting, strip-rolling the cast strip to a rolled strip, cross-cutting the rolled strip to metal sheets, rolling the metal sheets to a final thickness, the rolling of metal sheets being carried out, in relation to the metal sheets, in a direction a at right angle to the rolling direction of the strip-rolling, said direction being maintained during the entire rolling of the metal sheets. The method according to the invention enables very wide sheets to be produced in a simple way which meet the end user's requirements.

1 . A method for producing metal sheets from a magnesium melt comprises the following steps:
 producing the magnesium melt,   casting the magnesium melt to a cast strip,   immediately after casting, strip-rolling the cast strip to a rolled strip,   cross-cutting the rolled strip to metal sheets,   rolling the metal sheets to a final thickness, the rolling of metal sheets being carried out, in relation to the metal sheets, in a direction at a right angle to the rolling direction of the strip-rolling, said direction being maintained during the entire rolling of the metal sheets.   
     
     
         2 . Method according to  claim 1 , wherein rolling of the metal sheets is carried out in several rolling passes. 
     
     
         3 . Method according to  claim 1 , wherein the metal sheets are heated to an initial rolling temperature, if their temperature is below 200° C. 
     
     
         4 . Method according to  claim 2 , wherein the metal sheets are heated to an initial rolling temperature between each rolling step. 
     
     
         5 . Method according to  claim 1 , wherein the finish-rolled metal sheets are subjected to final annealing at 330° C.-360° C.
