Abstract

The invention provides a semicontinuous casting device and method of an aluminum alloy, and belongs to the technical field of casting equipment of the aluminum alloy. The semicontinuous casting device and method are provided so as to improve the quality of aluminum alloy ingots, refine structures of cast ingots, and lower harmful effects generated by oxides gathering in molten aluminum on the aluminum alloy ingots and subsequent deep-processed products. The semicontinuous casting device consists of a flow supply system, a shearing system, a crystallization system, a stirring system and a traction system. The semicontinuous casting device is provided with the shearing system on the basis of conventional semicontinuous casting of the aluminum alloy; through an upper coil, a variable-frequency power source and a flow-guide-pipe partition board in the shearing system, the molten aluminum in a flow guide pipe flows intensely and quickly, and the generated powerful shearing force scatters gathered oxidation films in the molten aluminum; the stirring effect of a low-frequency electromagnetic field is utilized to uniformly scatter mass points of the scattered oxidation films to different positions in a crystallizer, so that solidification structures are refined, and the comprehensive performance of the aluminum alloy is improved.
