Abstract (en)

[origin: EP2208547A1] A magnesium alloy hot rolling method includes: a first rolling step in which a magnesium plate (M0, M1) is rolled reciprocatingly between an upstream heating furnace (2) which is located on an upstream side of a rolling mill (1) and which heats the magnesium plate (M0, M1), and a upstream heating furnace (3) which is located on a downstream side of the rolling mill (1) and which heats the magnesium plate (M0, M1); and a second rolling step in which the temperature of respective end portions of the magnesium plate (M0, M1) on both the upstream and downstream sides is maintained while the magnesium plate (M0, M1) is being rolled reciprocatingly between an upstream temperature maintaining apparatus (5) which transports the heated magnesium plate (M0, M1) while maintaining the temperature thereof, and a downstream temperature maintaining apparatus (6) which transports the heated magnesium plate (M0, M1) while maintaining the temperature thereof. According to the magnesium hot rolling apparatus of the present invention and to the magnesium hot rolling method of the present invention which uses this apparatus, it is possible to prevent any deterioration in the quality of a product which is due to temperature variations during the hot rolling of magnesium alloy.
