METHOD AND APPARATUS FOR CASTING ALLOY USING VIBRATION

摘要

PURPOSE: A method for casting an alloy whose mechanical properties are greatly improved by adding vibration to mold so that grains of the alloy are micronized is provided, and a casting apparatus used in the alloy casting method is provided. CONSTITUTION: In a method for casting an alloy by injecting liquid metal into mold, the method for casting alloy using vibration comprises the steps of injecting the liquid metal into the mold; and applying mechanical vibration having frequency of 5 to 500 Hz and amplitude of 1 to 20 mm to the mold before the liquid metal is solidified, wherein the method comprises the step of inoculating the liquid metal into the mold as applying vibration to the mold. In a casting apparatus comprising mold, the casting apparatus(10) comprises a supporting plate(7) which is vertically freely slid along a plurality of supporting bars(6), and on which the mold(1) is rested; an eccentric body of revolution(3) which is connected to a lower part of the supporting plate(7) so that the supporting plate(7) is vertically reciprocated according to rotation of the eccentric body of revolution(3); and a motor(4) which rotates the eccentric body of revolution(3), and at which frequency controller(5) for changing frequency is installed.
