  • Patent number: 9604267
    Abstract: There are provided a method for producing a magnesium alloy sheet having good press formability and a magnesium alloy coil stock obtained by coiling the magnesium alloy sheet. After a raw material sheet 1 composed of a magnesium alloy is preheated to 280° C. or less, the heated raw material sheet 1 is rolled with a reduction roll 3 and the obtained long rolled sheet is coiled. The surface temperature of the reduction roll 3 is set to be 230° C. or more and 290° C. or less. The preheating, rolling, and coiling are repeatedly performed in a continuous manner. By setting both the temperatures of the raw material sheet 1 and reduction roll 3 to be certain temperatures, the rolling property of the raw material sheet can be improved and the raw material sheet can be properly rolled in a continuous manner. In addition, a variation in temperature in the width direction of the reduction roll can be suppressed and uniform rolling can be performed, resulting in the production of a long magnesium alloy sheet.
