Abstract

The invention relates to a non-vacuum smelting device. The non-vacuum smelting device comprises a first furnace (1), a second furnace (2) and a third furnace (3), wherein a connecting channel (4) is arranged between the second furnace (2) and the third furnace (3); a graphite spiked club autoleveler (5) is arranged in the middle of the connecting channel (4); and electrical coils (6) are respectively wound on the outer sides of the connecting channels (4) on two sides of the graphite spiked club autoleveler (5). Continuous production of copper-chromium-zirconium alloy contact wires is realized, and is not affected by the capacity of the furnaces, the copper-chromium-zirconium alloy contact wires which have optional lengths and meet ingredient requirements can be produced, and requirements of development of high speed railways in the future can be met.

Description

technical field [0001] The invention relates to a non-vacuum smelting device, which is mainly used for continuous production of large-length, high-strength, high-conductivity copper-chromium-zirconium alloy contact wires. Background technique [0002] With the development of electronic information technology, the requirements for the comprehensive performance of copper alloy conductive materials are getting higher and higher. It is required to maintain high electrical conductivity and thermal conductivity while maintaining high strength (hardness), toughness, and wear resistance. Sex, cold resistance, non-ferromagnetic and other characteristics. These excellent properties make copper alloys gradually become important metal materials used in high-tech fields such as electric power, information, transportation, energy, light industry and aerospace. In many occasions, it is rarely used in the form of pure copper. This is because the strength of pure copper is low (230-300 MPa)...
