Abstract
A vacuum smelting device with mold-temperature control design includes: a chamber body and a cabin door, wherein the chamber body and the cabin door form a vacuum closed space; a smelting crucible disposed in the vacuum closed space for smelting raw materials to a molten metal; a casting mold also disposed in the vacuum closed space for accommodating the molten metal poured from the smelting crucible, and solidifying the molten metal to an as-cast alloy; and a mold-temperature control module surrounding the casting mold for controlling the temperature of the casting mold.
Claims7
A method of manufacturing a Ti—Al intermetallic alloy comprising the following steps of:
- providing a vacuum smelting device, wherein the vacuum smelting device comprises:
- a chamber body and a cabin door, wherein the chamber body and the cabin door form a vacuum closed space;
- a smelting crucible disposed in the vacuum closed space;
- a casting mold also disposed in the vacuum closed space;
- and
- a mold-temperature control module surrounding the casting mold;
- placing a plurality of raw materials of the Ti—Al intermetallic alloy in the vacuum smelting device, and melting the plurality of raw materials to a molten metal soup of the Ti—Al intermetallic alloy in the closed vacuum space;
- and
- controlling the temperature of the casting mold in the same closed vacuum space, pouring the molten metal soup of the Ti—Al intermetallic alloy into the casting mold, and solidifying the molten metal soup to an as-cast alloy;
- wherein when the as-cast alloy is a Ti—Al intermetallic as-cast alloy and the casting mold is a ceramic mold, the mold temperature control module controls the temperature of the ceramic mold between 1300° C. and 900° C., and the temperature holding time is:
- 2-4 hours.
