Title:
DEVICE AND METHOD FOR COMBINED-FREQUENCY ULTRASOUND SEMI-CONTINUOUS CASTING OF MAGNESIUM ALLOY
Document Type and Number:
WIPO Patent Application WO/2021/012351
Kind Code:
A1
Abstract:
A device and method for combined-frequency ultrasound semi-continuous casting of a magnesium alloy, the device comprising a tundish (16), which is internally provided with two ultrasound generating devices, the front end face of an ultrasound irradiation rod of each ultrasound generating device being located in the tundish (16); a transducer and a support device are assembled together; and the support device is a lifting support device or a variable angle support device. The method comprises: (1) smelting a magnesium alloy melt; (2) preheating the tundish (16), a pipette (8) and the two ultrasound irradiation rods; inserting the ultrasound irradiation rods into the tundish (16), or inserting same into the tundish (16) after an included angle is adjusted; (3) conveying the magnesium alloy melt to the tundish (16), and starting up the ultrasound generating devices; (4) starting up a crystallizer (5); and (5) conveying the magnesium alloy melt in the tundish (16) into the crystallizer (5), and performing semi-continuous casting.
