Patent ID: 8220526

Claim:
A method for continuous and efficient casting roll of magnesium alloy plates comprising: providing plural induction furnaces, a resistance furnace, a casting roll and rollers; adding metal elements into the induction furnaces, the metal elements comprising Mg ingots or Mg alloy, the metal elements being smelted in the induction furnaces and then flow into the resistance furnace; controlling a temperature of the Mg melt in the resistance furnace, wherein there are at least two temperature controlling areas communicated with each other, and a difference of temperature is constant; transferring the Mg melt into a biting area through a transferring pipe and modeling the Mg melt into Mg plate, the temperature of the Mg melt into the biting area being 690±10° C.; and rolling the Mg plate in the rollers and each band of the rollers having a working temperature 250˜350° C., and a difference of temperature between the each band of the rollers is ±10° C., wherein the resistance furnace has at least one spacer disposed therein, thereby defining the at least two temperature controlling areas and arranged in an order from a temperature controlling area with a highest temperature to a temperature controlling area with a lowest temperature in a direction of the Mg melt casting.
