Abstract:
     The invention relates to a method for producing AZ31 magnesium alloy sheet, at 300MPa level and isotropic property, wherein the invention uses magnesium alloy electromagnetic low-temperature semi-casting method to produce blank to be uniformly annealed, milled and compressed at 200-400Deg. C into sheet band, while the compress ratio is 8-15 and the thickness of compressed sheet is 5-20mm; then cutting the compressed sheet into the sheets whose width is 10-30mm, to be heated to 300-400Deg. C; then preheating the roller of rolling machine, vertically to the former extrusion direction, to obtain the sheet whose width is not higher than 500mm and thickness is 0.3-1.0mm; via combining the extruding temperature and rolling temperature, obtaining the sheet with high plasticity or high strength; then cutting edge, coating protective film and packing. The invention has simple process, low cost, and high property, while the anti-drawing strength is 300MPa level.
