METHOD AND APPARATUS FOR PRODUCING THIN MAGNESIUM BASED ALLOY PLATE

摘要

A method for producing a thin magnesium based metal plate which comprises a casting step comprising supplying a molten metal of a magnesium based metal to a molten metal vessel, withdrawing the molten metal, and supplying it to the interstice of a casting twin-roll comprising a casting upper roll and a casting lower roll while applying a pressure to it, to cast it into a plate having a predetermined thickness and a predetermined temperature, and a rolling step comprising applying a pressure to the above cast plate with at least one pair of rolling rolls, to thereby produce a thin magnesium based metal plate; and an apparatus for practicing the method. The method has allowed the production of a thin magnesium based metal plate by plastic working with good efficiency, without the need of supplying additional heat energy in the rolling step.
