Embodiment Construction

[0038] The specific implementation manners of the present invention will be further described below in conjunction with the accompanying drawings and technical solutions.

[0039] figure 1 A device for horizontal continuous casting of electromagnetic / ultrasonic coupled fields under vacuum is shown. Before smelting the alloy, move the draw bar 20 and the continuous casting slab 26 to the initial position so that the end of the continuous casting slab 26 is located in the graphite mold 24, and then put the alloy raw material into the melting furnace 3 and prepare for smelting; during smelting, first Open the isolation valve 12, and close the exhaust vent 14 and the inert gas valve 29, then by controlling the vacuum control system 8, turn on the vacuum pump 13, and then vacuumize the first vacuum chamber 1 and the second vacuum chamber 2 to 0.01Pa, and then close the vacuum pump 13 Open the inert gas valve 29 afterwards, fill argon gas to 0.05MPa in the first vacuum chamber 1 an...

Description

technical field [0001] The invention belongs to the technical field of metal material preparation, and relates to an integrated device and method for smelting and acoustic-magnetic coupling continuous casting under vacuum conditions. Background technique [0002] According to the principle of electromagnetic induction, the electromagnetic force generated by the alternating magnetic field can be decomposed into the supporting force in the horizontal direction and the stirring force in the vertical direction. There is a significant difference in the action rules of the melt: the low-frequency magnetic field can generate a large stirring force, and the electromagnetic stirring effect inside the melt is obvious. But at the same time, because of the strong stirring effect, the fluctuation of the melt in the molten pool will be aggravated, and the surface of the liquid metal is easy to crack, which will adversely affect the protection of the alloy during casting. The oxide film o...
