specific Embodiment approach 1
[0038] Specific implementation mode one, has the following steps successively:
[0039] Pour the liquid magnesium alloy 1 metal that has been smelted in the crucible 2 into the holding furnace 3. During the whole process, the holding furnace is carried out under the protection of argon. In this scheme, the temperature of the smelted magnesium alloy and the holding furnace are set It is 730°C. The magnesium alloy material is taken as Mg-10Gd-3Y-2Ag-0.4Zr.
[0040] In order to prevent the magnesium alloy 1 from flowing out prematurely, before the magnesium alloy reaches 2 / 3 of the capacity of the holding furnace 3, the valve 4 of the furnace is in a closed state.
[0041] In order to make the surface temperature of the metal sheath 6 uniform and to reduce energy waste, the cooling device 7 is turned on while adding the amount of liquid magnesium alloy, so that the cooling medium is injected from the lower end and flows out from the upper end. The cooling medium water selected i...
