Abstract

The invention discloses a real-time regulation and control wall surface resonance ultrasonic metal solidification device and method. The device comprises a metal solidification device body and a metal solidification data acquisition and control device, and the metal solidification device body comprises a casting mold, an ultrasonic vibration assembly and a thrust rod. The method comprises the steps that firstly, alloy raw materials are loaded; secondly, the metal solidification device body is mounted; thirdly, a sensor group is mounted; fourthly, initial values of vibration parameters are set; fifthly, the resonance frequency of the casting mold is searched for; sixthly, a master alloy is smelted; seventhly, melt pouring is conducted; eighthly, wall surface vibration three-dimensional ultrasonic metal solidification under vibration frequency feedback control is conducted; and ninthly, a casting is unloaded. The problem of overheating failures caused by direct contact of an amplitude-change pole and melt is avoided, the problems of low transmission efficiency and special hardware development cost are solved, the problem that in the prior art, the ultrasonic vibration treatment effect becomes poor due to continuous changing of resonance points is solved, the speed of searching for the optimal vibration frequency is greatly increased, and effective regulation and control over the solidification structure are realized.
