Problems solved by technology

[0004] However, this method has a long production cycle, because it is cast in one furnace, the length, weight and shape are limited, and the vacuum production cost is high and the output is small, so it is difficult to establish a continuous industrial production scale

Abstract

The invention discloses a non-vacuum continuous production process and production equipment of copper chromium zirconium alloy. The production process comprises the following steps: adding standard cathode copper and copper chromium intermediate alloy into a smelting furnace, closing the smelting furnace and filling the smelting furnace with protective gas for smelting; after the smelting is finished, opening an undercurrent passage valve and injecting molten-state alloy liquid into a heat preserving furnace through a standing cavity; when the temperature of the heat preserving furnace reaches 1,180-1,200 DEG C, starting upward continuous casting equipment to perform casting; feeding a cast copper chromium zirconium alloy rod into a straightener to straighten and then performing extrusion molding through a continuous extruder. According to the non-vacuum continuous production process of the copper chromium zirconium alloy, the production difficulty can be reduced and the aim of continuous production is achieved.

Description

technical field [0001] The invention relates to the production of copper-chromium-zirconium alloys, and particularly designs a production equipment and production process for continuously producing copper-chromium-zirconium alloy materials under non-vacuum conditions. Background technique [0002] Copper-chromium-zirconium alloy materials have excellent properties such as high strength, high electrical conductivity, and high softening temperature, and are widely used in welding electrodes, lead frames, motors, auto parts, cast steel, and cast copper crystallizers. Alternative materials for contact wires. [0003] Copper-chromium-zirconium alloy material is based on copper, adding metal chromium and metal zirconium. Because metal chromium and metal picks are easy to react with oxygen under high-temperature melting and casting conditions, the current production of copper-chromium-zirconium alloy materials is limited. In vacuum melting and casting, the ingot is produced throug...
