Description

Low-porosity alloy preparation auxiliary device Technical Field The utility model relates to the technical field of alloy preparation, in particular to an auxiliary device for preparing low-porosity alloy. Background With the continuous rising of the performance requirements of alloy materials in the modern industry, low porosity becomes a key index for measuring the quality of the alloy. The existence of the air holes not only weakens the mechanical properties of the alloy, but also can cause hidden dangers such as fatigue cracks and the like, and seriously influences the application of the alloy in the high-end fields such as aerospace, automobile manufacturing and the like. During smelting, gas (such as hydrogen and oxygen) is dissolved in the melt or reacts with air, so that air holes are easily formed during solidification, and the mechanical properties of the material are reduced.
