Abstract

The invention provides a continuous casting and direct forming die for a copper clad aluminum composite material with an irregular section, and a process thereof. The adopted die is composed of an outer die 3 and a core pipe 4, wherein the shape and thickness of a copper clad aluminum composite casting blank cladding layer are jointly controlled by the cavity size of the outer die 3 and the overall dimension of the core pipe 4; and the dimension of aluminum at the core part is controlled by the overall dimension of the core pipe 4 so as to control the shape and cladding thickness of the copper clad aluminum composite material. The copper clad aluminum irregular blank continuous casting one-step forming technology provided by the invention shortens the technological process, has high production efficiency, dispenses with the procedure of surface pretreatment, ensures good interface combing performance, is capable of accurately controlling the section shape and cladding rate of a dual-metal irregular blank, facilitates operation and control, and obviously improves the yield of finished products.

Description

[0001] technical field [0002] The invention belongs to the technical field of continuous casting, and provides a horizontal continuous casting direct composite forming mold of copper-clad aluminum composite materials with special-shaped cross-sections and a process thereof. Background technique [0003] Bimetal shaped cross-section composite materials are widely used in electrical, petroleum, aerospace and other fields. For example, copper-clad aluminum composite busbars with rectangular cross-sections can be used in large-current transmission fields such as bus trunk systems, power transmission and distribution systems , Low-voltage complete switchgear, control equipment and other industries instead of pure copper busbars. [0004] The preparation techniques of copper-clad aluminum composite materials with special-shaped cross-sections that have been publicly reported mainly include the following types: [0005] The first method is hydrostatic extrusion. The hydrostati...
