Technical Field

[0001] The invention relates to the technical field of high-temperature alloy pouring, and in particular to a high-temperature alloy simultaneous pouring device and method. Background Art

[0002] At present, the pouring of high-temperature alloy master alloys is completed in a vacuum environment. When it comes to multi-frame pouring, there are usually two methods used: 1. After the pouring of one frame is completed, the crucible is turned back, and then the mold cart is moved to wait for the next set of molds to reach the pouring position, and then the crucible is turned over for pouring. The operation is cyclical until the pouring is completed; 2. Keep the crucible tilted, place a bridge between the frames, and move the mold cart for pouring after the pouring of one frame is completed.

[0003] In the above methods, the movement of the crucible or the mold cart needs to be controlled during the pouring process, which involves the coordination between the pouring personnel and the mold cart personnel. Mismatches in coordination may lead to steel spillage or excessive / inadequate pouring, resulting in material waste and unqualified finished products. Summary of the invention

[0009] Furthermore, the flow divider is connected to the mold tube through the flow guide hole.

[0010] Furthermore, the central groove is connected to the flow channel through a liquid inlet.

[0011] The present invention also provides a method for simultaneous pouring of high-temperature alloys, which uses any of the above-mentioned simultaneous pouring devices for high-temperature alloys to perform pouring.
