Abstract

The invention provides a new method for preparing aluminium alloy plates and strips for deep drawing, in particular to a multiple-energy-field asymmetric sunken type cast-rolling method. The method comprises the steps of leading a refined aluminium alloy melt into a roller gap of a cast-rolling mill having electromagnetic / ultrasonic composite energy fields through asymmetric casting nozzles which are installed in a sunken mode, under the effects of stirring and vibrating impacting of the electromagnetic / ultrasonic composite energy fields, climbing, returning and stirring of the aluminium melt in a cast-rolling area and forced cooling and rolling deformation of rollers, strengthening heat transfer, mass transfer and energy conversion of the cast-rolling area, achieving crystal nucleus propagation, and changing solidification behavior, so that the aluminium alloy plates and strips are produced through cast-rolling continuously. The aluminium alloy plates and strips prepared by the method are bright and clean in plate surface, neat in edge, small and uniform in grain, low in anisotropism and excellent in deep drawing performance, and the method is short in whole production flow, high in efficiency, low in product cost, high in product quality and applicable to batch production of the aluminium alloy plates and strips for the deep drawing.
