Description

Technical Field

[0001] The utility model relates to the technical field of alloy melting furnace degassing equipment, in particular to a degassing machine for an alloy melting furnace. Background Art

[0002] When the alloy is melted, there will be gas inside the solution, which will affect the quality of subsequent casting processing. Therefore, the alloy needs to be degassed when it is melted. The gas in the solution can be removed, which also helps to improve the purity and stability of the alloy melt, and can reduce the porosity defects in the casting, thereby ensuring the quality of the casting.

[0003] When the current degasser is in use, the molten alloy solution is usually poured into the degassing box, and then the alloy solution is stirred, and the gas in the alloy solution will be discharged. However, since a large amount of alloy solution is piled up together, the gas distribution in the solution is not uniform during stirring, which makes it difficult to discharge some gases, thus affecting the effect of gas removal. For this reason, we provide a degasser for an alloy melting furnace. Utility Model Content
