Abstract

A device and method for preparing aluminum alloy composite tube blanks, belonging to the technical field of metal material preparation. The device includes: outer crystallizer, inner crystallizer, core mold, bracket, ingot and casting machine; preparation method: 1) When the water pressure and oil pressure in the outer crystallizer, inner crystallizer and core mold are stable, the core material The melt flows into the inner cavity; 2) When the core material solidifies shell is formed in the outer layer, the composite layer melt flows into the outer cavity through the outer crystallizer diverter plate; the casting machine is started; 3) The composite layer melt and the core material solidified shell form a composite interface, the composite pipe blank is produced; when the composite pipe blank reaches the predetermined length, the flow supply is stopped. The preparation device and method of the present invention solve the problems of uneven circumferential temperature distribution and excessive and under-recombination of the interface, eliminate segregation and segregation phenomena, reduce the friction between the core material solidification shell and the core mold, and realize direct composite casting. Forming, the invention has simple equipment, short process, low energy consumption and high 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...
