Equipment for preparing chromium zirconium copper alloy wire pole by electromagnetic stirring fusion metallurgy

Abstract

The invention relates to a device for preparing an alloy mast through electromagnetic stirring and melting, wherein the alloy is made from chromium, zirconium and copper. A baffle is arranged in the middle part of a furnace body to divide the furnace body into a melting furnace part and a holding furnace part; the furnace bottom of the melting furnace part is higher than that of the holding furnace part; an electromagnetic stirrer is arranged on the outer side of the melting furnace part, and a melting furnace sensor is arranged at the lower part of the melting furnace part; and a holding furnace sensor is arranged at the lower part of the holding furnace part, and an up-pulling system is arranged above the holding furnace part. Under a non-vacuum condition, the device can realize continuous preparation of the alloy (containing chromium, zirconium and copper) mast which is easily oxidized and difficult in adding element zirconium; the manufacturing technology for the alloy mast is greatly simplified, a product with uniform and stable components can be acquired, the production cost can be reduced, and the device is worthy of promotion.

Description

technical field [0001] The invention relates to equipment for preparing chromium-zirconium-copper alloy wire rods, in particular to a non-vacuum electromagnetic stirring smelting equipment for preparing chromium-zirconium-copper alloy wire rods, and belongs to the technical field of non-ferrous metal processing. Background technique [0002] Due to its high strength and electrical conductivity, chromium-zirconium-copper alloys are widely used in electronics, electric power, automobiles, light industry, transportation and other industries, and have broad market application prospects. However, because Zr is easily oxidized and burned in the atmosphere, it is difficult to produce Cr-Zr-Cu alloy wire rods without vacuum. The non-vacuum preparation of the alloy and the short-process production method can achieve energy saving, consumption reduction, environmental protection, and have excellent social benefits. Chromium-zirconium-copper alloy wire rods are produced under non-vacu...

AI Technical Summary

Problems solved by technology

There are some limitations in completely closed non-vacuum melting and casting equipment: ① It is difficult to feed materials. At present, most of the designs of sealed non-vacuum melting equipment are to cover the induction furnace for protection. The furnace cover has a feeding port and an observation window, because these windows are relatively small. , so it is not conducive to a large number of continuous feeding and observation; ② cannot achieve continuous preparation well, most non-vacuum melting chromium-zirconium copper alloys cannot achieve continuous production, because the reason for equipment design is usually melting one furnace casting one Furnace, need to stop and open the furnace cover to feed; ③Without field intervention device, alloy with relatively uniform and stable composition cannot be obtained
