Abstract

A semi-continuous casting equipment for thin-walled alloy castings with equal outer diameter, optimized by synergistic action of traveling magnetic fields and ultrasonic wave, includes: a melting and insulation device, a heat insulation panel, a traveling magnetic field generator and a water-cooled crystallizer sequentially positioned on a working platform; an outer mold positioned on the water-cooled crystallizer and sleeved the traveling magnetic field generator; a mold core inside the outer mold defining a casting cavity; a bottom plate below the mold core capable of sliding against and along an inner side of the outer mold; two position control units supported by the working platform; an ultrasonic limit baffle moveably engaged with the position control units; an ultrasonic wave generator affixed on the ultrasonic limit baffle and extended to the casting cavity; a motion system controlling up and down movement of the bottom plate and the position control units through a gear transmission mechanism.
