Description

Technical Field

[0001] The utility model relates to a zinc alloy refinement device, in particular to an ultrasonic grain refinement device for die-casting zinc alloy, belonging to the technical field of zinc alloy refinement. Background Technique

[0002] Aluminum-titanium-boron wire is an auxiliary material for metal smelting and refining. It is composed of elements such as aluminum, titanium, and boron, and can play roles such as anti-oxidation, deoxidation, and process simplification during the metal smelting process. Zinc is likely to form large grains in the molten liquid, which has a great impact on the material properties. Therefore, during the production process of zinc alloy, refinement treatment is required to minimize the grains of zinc.

[0003] However, during the use of the existing zinc alloy refinement device, it is usually refined by adding rare earth elements or aluminum to improve the organizational structure of the zinc alloy and increase the strength and plasticity of the zinc alloy. When feeding materials, the feeding amount cannot be adjusted according to the amount of zinc alloy, and the use effect is not very good; after melting, the zinc alloy will have a mixture of fine particles and coarse particles. If the zinc alloy is directly poured in, it will cause the fine particles to react with the rare earth elements and be further refined. And for some coarse particles, the fine particles may react with the rare earth elements completely and additional rare earth elements need to be added for reaction and refinement, resulting in the need to add too many auxiliary materials and reducing the practicability of the device.
