Abstract
The invention relates to a method for producing a magnesium hot strip, in which a melt from a magnesium alloy is continuously cast to form a roughed strip with a thickness of maximum 50 mm, and in which the cast roughed strip is hot-rolled directly from the cast heat at a hot-rolling initial temperature of at least 250° C. and maximum 500° C. to form a hot strip with a final thickness of maximum 4 mm, whereby in the first hot-rolling pass a reduction in the thickness of at least 15% is achieved. With the method according to the invention, magnesium sheets with improved deformability can be produced with reduced manufacturing effort and expenditure.
Claims11
A method for producing a magnesium hot strip, comprising:
- (a) continuously casting a melt of a magnesium alloy in a casting heat to form a roughed strip having a maximum thickness of 50 mm, and
- (b) hot rolling the cast roughed strip directly from the casting heat at a hot-rolling initial temperature of at least 250° C. up to a maximum of 500° C. to form a hot strip having a maximum final thickness of 4 mm,
- (c) whereby in the first hot-rolling pass, a reduction in thickness of at least 15% is achieved.
