Abstract

The invention discloses a continuous casting method and a continuous casting method for an aluminum alloy compounded ingot and belongs to the technical field of aluminum alloy casting. The device comprises a split crystallizer, an alloy liquid distributor, a hot top plate and a dummy ingot; the upper part of the dummy ingot is fixedly connected with two baffle plates; the upper part of each baffle plate is connected with a cooling plate; and two cooling plates divide the interior of the split crystallizer into a core material melt cavity and a coating material melt cavity. The method comprises the following steps of: smelting, refining and standing two kinds of alloys to be compounded; introducing cooling water into a cooling plate water cavity and a water box and keeping the water flowing; leading the core material alloy liquid into the core material melt cavity; leading the coating material alloy liquid into the coating material melt cavity; and starting the aluminum alloy and casting. The device and the method can ensure that the coating material alloy liquid flow uniformly and has a stable liquid surface and uniform temperature, and can eliminate the triangular area with high cooling intensity, ensure that a supporting surface formed under the cooling plate has the uniform temperature along the horizontal direction of the cooling plate and ensure the comprehensive metallurgical combination of the compounded surface.

Description

technical field [0001] The invention belongs to the technical field of aluminum alloy casting, and in particular relates to a continuous casting method and a device for aluminum alloy composite ingot casting. Background technique [0002] Due to the single performance of conventional aluminum alloys, they cannot well meet the comprehensive requirements of multiple performances in engineering such as vehicles, structures, and electronics. Therefore, composite materials have become the focus of new material research and development. Due to its low cost and high comprehensive performance, layered composite materials are the most widely used composite materials with the largest production volume. Among them, composite aluminum materials have high strength, and at the same time have comprehensive properties such as corrosion resistance (decoration), weldability, and easy forming. It is the fastest growing composite material, and composite sheet and strip is currently the most use...
