Ultrasonic magnesium melt improvement equipment
The equipment is suitable for major universities, research institutes and factories, and special needs can be customized.
High energy ultrasound has a unique acoustic effect. Ultrasonic vibration is introduced during the solidification process of the metal, and the solidified structure changes from coarse columnar crystal to uniform fine equiaxed crystal, and the macroscopic and microsegregation of the metal is improved. In general, when ultrasonic waves propagate in a liquid medium, mechanical, thermal, optical, electrical, and chemical effects are produced by mechanical action, cavitation, and heat. In particular, high-powered ultrasonic waves generate intense cavitation, which creates transient high temperatures, high pressures, vacuums and micro-jets locally, while ultrasonic aluminum melt equipment is a high-power ultrasonic device specifically used in the metal foundry industry. With the increasing requirements for materials, the processing technology has become more and more complicated. The 20K ultrasonic metal melt processing equipment, also known as the 20k ultrasonic metal crystallization system, is a high-power ultrasonic equipment specially used in the metal casting industry. It mainly acts on the crystallization process of molten metal, can significantly refine the metal grains, uniform alloy composition, accelerate bubble movement, and significantly improve the strength and hardness of the metal material.

Principle:
The device -Ultrasonic Magnesium Melt Improvement Equipment consists of two parts: an ultrasonic vibration component and an ultrasonic generator. Ultrasonic waves are added to the alloy solution to generate a periodic positive pressure-negative pressure effect during conduction, so that the temperature and chemical composition of the alloy solution are uniformed, and the solidification mode is converted into a volume. The solidification method refines the alloy structure, reduces the segregation tendency of the alloy, and improves the uniformity of the metal cast structure.
After semi-continuous casting after melt sonication, the solidification structure of the ingot is uniform, the defects are less, the macroscopic cracking phenomenon is suppressed, and the electrical conductivity, tensile strength and elongation of the alloy are improved.
