Production process and device for large-length copper-based amorphous alloy contact line for high speed railway

Abstract

The invention relates to a production process for a large-length copper-based amorphous alloy contact line for a high speed railway. The production process comprises the following steps of (1) smelting through an Ar atmosphere protected non-vacuum semi-closed single channeling dual-body induction cooker; (2) carrying out semisolid treatment on an on-line melt; (3) carrying out continuous up casting on a T2 red copper mould; and (4) carrying out plastic working and forming on a copper-based amorphous alloy continuous up casting rod blank. According to the production process provided by the invention, the manufacturing difficulty of copper-based amorphous alloy is greatly reduced, and the manufacturing and the producing of the large-length copper-based amorphous alloy contact line for the high speed railway are realized, and the development demand on applying a casting process of a copper-based amorphous alloy to the high-strength high-conductive contact line for the high speed railway in a modern industry and in the further is met.

Description

technical field [0001] The invention relates to a production process and equipment for a large-length copper-based amorphous alloy contact wire for high-speed railways. Background technique [0002] The arrangement of metal atoms in amorphous alloys is similar to that of liquid metal, and has the structural characteristics of liquid metal atoms in disordered arrangement. There is no crystal structure, so the structural defects of amorphous alloys are usually limited to a few atomic sizes. Like crystalline metal materials, when the external force is large enough, the slip occurs preferentially on a specific grain boundary or crystal plane. Based on this characteristic of amorphous alloy, its mechanical properties, electrical properties and chemical properties are very excellent, and it is widely used in the manufacture of superconducting materials and semiconductor materials. [0003] At the same time, with the rapid development of electronic information engineering technolo...

Problems solved by technology

However, in the actual preparation process of Cu-Zr-Al-Ag amorphous alloy, Zr element is easy to oxidize and volatilize, the formation of amorphous is discontinuous, the forming process of large-size amorphous is complicated, and the degree of crystallization of amorphous alloy is large. Traditional copper alloy smelting, casting and processing have difficulties such as high difficulty in production control, high cost, and unstable mass production quality, which seriously hinders the industrial production and application of Cu-Zr-Al-Ag amorphous alloy
