Abstract

The invention relates to a preparation device and method for an aluminum alloy composite pipe base, belonging to the technical field of metal material preparation. The device comprises an outer crystallizer, an inner crystallizer, a core mold, a support, a dummy ingot and a casting machine. The preparation method comprises the steps (1) a core material melt flows to an inner cavity when the water pressure and oil pressure in the outer crystallizer, the inner crystallizer and the core mold are stable; (2) a composite layer melt flows to an outer cavity through a splitting plate of the outer crystallizer when a core material solidification shell is formed in an outer layer, and the casting machine is started; and (3) the composite pipe base is prepared when the composite layer melt and the core material solidification shell form a composite interface, and flow supply is stopped when the composite pipe base reaches a preset length. By adopting the preparation device and method, the problems of nonuniform distribution of interface circumferential temperature and excessive and insufficient compounding are solved, the segregation and clustering phenomena are eliminated, the friction force between the core material solidification shell and the core mold is reduced, and direct composite casting forming is realized; and the device and method are simple in equipment, short in process, low in energy consumption and high in production efficiency.

Description

technical field [0001] The invention belongs to the technical field of metal material preparation, and in particular relates to a preparation device and method for an aluminum alloy composite tube blank. Background technique [0002] Aluminum alloy composite pipe is a layered composite material composed of two or more aluminum alloys. Since the characteristics of each component of the composite pipe can be fully utilized, the composite material can achieve a combination of various properties, such as high strength and wear resistance. , High strength and corrosion resistance, high strength and brazing, high strength and high conductivity, corrosion resistance and brazing, etc. Therefore, the application of aluminum alloy composite pipes has increased significantly. Widely used in automobiles, ships, machinery, petrochemical, power electronics and aerospace, aviation industry. [0003] The traditional production method of aluminum alloy composite pipe is the extrusion compo...
