Abstract

The invention discloses a system for casting alloys and a method for processing castings, belonging to the field of casting devices. The system includes an ultrasonic device, a mold and a heating device. The ultrasonic device includes: a bracket, an ultrasonic generator and an ultrasonic vibrator. A gate and a riser are arranged on the top surface of the mold. The other end of the ultrasonic vibrator is located in the gate, and the heating The device is arranged on the outer wall of the mould. The method includes: preheating the mold; preheating the ultrasonic vibrator; pouring the alloy into the mold from the gate; vibrating the alloy; after the alloy is mixed evenly, removing the heating device, and the ultrasonic vibrator continues vibrating the alloy; , stop the vibration; take out the casting. The ultrasonic device of the system can extend into the mold, preheat the mold in advance through the heating device, and prevent the alloy from being poured into the cold mold and cooled and solidified in advance. The method can realize ultrasonic vibration in a closed mold, so that alloys with higher mechanical properties can be cast.

Description

technical field [0001] The invention relates to the field of casting devices, in particular to a system for casting alloys and a method for processing castings. Background technique [0002] In the alloy casting process, in order to improve the mechanical properties of the alloy casting, rare earth elements are added to the alloy. In order to make the added rare earth evenly distributed in the alloy, ultrasonic vibration can be used on the alloy during the casting process. [0003] When casting existing magnesium alloys, castings with a relatively simple structure can be prepared through an open mold. When the open mold is subjected to ultrasonic vibration, the ultrasonic vibrator is directly inserted into the molten alloy in the open mold; if When preparing castings with complex structures, closed molds can be used. [0004] In the process of realizing the present invention, the inventor finds that there are at least the following problems in the prior art: [0005] In th...
