Method and device for equalizing the solidification process of a molten metal particularly produced during strand or strip casting

Abstract

The invention relates to a method of equalizing a solidification process of molten metal produced, in particular, during strand or strip casting, wherein the molten metal ( 10 ) is subjected, in particular, to an electromagnetic stirring process, and wherein a magnetic field is applied to metal located upstream of the area of, in particular, the electromagnetic stirring process. According to the invention, it is provided that during the solidification process, at least one magnetic field is applied to an already solidified, at the outside, into a strand, region ( 11 ) of the molten metal ( 10 ). The invention also relates to a device for carrying out this process.

1 . A method of equalizing a solidification process of molten metal produced, in particular, during strand or strip casting, wherein the molten metal ( 10 ) is subjected, in particular, to an electromagnetic stirring process, and wherein a magnetic field is applied to metal located upstream of the area of, in particular, the electromagnetic stirring process,
 characterized in that   during the solidification process at least one magnetic field is applied to an already solidified, at the outside, into a strand, region ( 11 ) of the molten metal ( 10 ).   
     
     
         2 . A method according to  claim 1 ,
 characterized in that   the electromagnetic field is applied to an already solidified, at the outside, into a strand, region ( 11 ) essentially at a bottom of the molten metal ( 10 ).   
     
     
         3 . A method according to  claim 1 ,
 characterized in that   a position of the electromagnetic stirring process is adapted in a casting direction.
