Abstract
The present application discloses an aluminum alloy low-pressure casting device and an aluminum alloy low-pressure casting process. A riser tube is canceled, and the pressure kettle replaces original injection of compressed air into a holding furnace, thereby reducing the consumption of compressed air, and improving the production efficiency of the low-pressure casting process. A non-return stopper is used to space the low-pressure casting and the holding furnace, and molten aluminum alloy can be added into the holding furnace in real time without interrupting the low-pressure casting process, so that rejects affected by temperature field changes due to interrupt of the continuous casting process can be reduced, and the yield of the casting process is improved.
