Abstract

The invention provides a horizontal continuous casting direct compound forming die and a process thereof for copper-clad aluminum composite materials with special-shaped cross-sections. The mold used is composed of an outer mold (3) and a core tube (4), and the copper-clad aluminum composite casting slab cladding is jointly controlled by the inner cavity size of the outer mold (3) and the outer dimension of the core tube (4). The shape and thickness of the layer; the size of the core aluminum is controlled by the external dimensions of the core tube (4), thereby realizing the control of the shape and cladding thickness of the copper-clad aluminum composite material. The one-time forming technology of continuous casting of copper-clad aluminum profiled billet shortens the technological process and has high production efficiency. Cover ratio, easy to operate and control, significantly improve the yield of finished products.

Description

technical field [0001] 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 [0002] 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. [0003] The preparation techniques of copper-clad aluminum composite materials with special-shaped cross-sections that have been publicly reported mainly include the following types: [0004] The first method is hydrostatic extrusion. The hydrostatic extrusi...
