Preparation device and preparation method of rare earth magnesium alloy

Abstract

The invention discloses a preparation device of a rare earth magnesium alloy. The preparation device comprises: a machine table; a heating furnace, which is connected with the machine table; a crucible, which is positioned in the heating furnace; and an ultrasonic assembly. The ultrasonic assembly comprises: an ultrasonic controller and a plurality of transducers which are electrically connected with the ultrasonic controller; an immersion type amplitude-change pole, which is connected with the transducers, wherein the end part of the immersion type amplitude-change pole is positioned in the crucible; and a leading-in type amplitude-change pole, which is connected with the transducers, wherein the leading-in type amplitude-change pole is located on the outer side of the crucible, and the leading-in type amplitude-change pole and the immersion type amplitude-change pole are oppositely arranged. According to the invention, the problems that magnesium alloy rare earth and other high-specific-weight components are prone to sedimentation, and rare earth phases are prone to enrichment in a grain boundary can be effectively solved.

Description

technical field [0001] The invention belongs to the field of casting molding of rare earth magnesium alloys, and in particular relates to a preparation device and method of rare earth magnesium alloys. Background technique [0002] In the metallurgical preparation process of rare earth magnesium alloys, there are problems such as uneven distribution of solutes, easy settlement of high specific recombinant elements, coarse rare earth phases and easy enrichment of grain boundaries, which greatly reduce the degree of homogenization and service reliability of magnesium rare earth alloy castings. [0003] Ultrasonic vibration is a simple, efficient, low-cost, and pollution-free advanced melt processing technology that can effectively refine the secondary phases in magnesium alloys. But for now, the traditional single-source immersion ultrasonic method has the limitations of fast energy attenuation, low flow level, and small action range, and cannot effectively solve the above-men...
