Abstract
The present invention relates to a process and to an apparatus for producing a magnesium sheet from a magnesium strip in a rolling device, said process having lower material heat losses compared to known processes and requiring a lower expenditure on apparatus. In the process, the magnesium strip, after preheating, is guided through at least one roll nip formed by at least one pair of counter-rotating working rollers, which comprise a main roller body. The process is characterized in that at least one of the two counter-rotating working rollers comprises at least one heat-insulating sheath surrounding the main roller body.
