Technique for preparing chromium zirconium copper alloy wire pole

Abstract

The invention relates to a preparation technology for an alloy mast, wherein the alloy is made from chromium, zirconium and copper. The technology comprises the following steps: adding industrial electrolytic copper into an inductive melting furnace for heating and melting, and covering the surface with graphite powder and charcoal at the same time; starting an electromagnetic stirrer for electromagnetic stirring and aided deoxidation treatment; adding a copper-chromium master alloy and zirconium wires for heating and melting after the industrial electrolytic copper is completely melted, and enabling the melt composition to be uniform by utilizing the electromagnetic stirring; then moving up the baffle between the inductive melting furnace and an inductive holding furnace so that the melt in the inductive melting furnace can be transferred into the inductive holding furnace under the action of the gravity, and covering the melt surface with the graphite powder and the charcoal; adjusting the melt temperature to 1200 DEG C to 1250 DEG C; and then starting an up-pulling system and continuously up-pulling CuCrZr alloy masts, and continuously adding new furnace burdens into the melting furnace during the up-pulling process. Under a non-vacuum condition, the technology can prepare the alloy (containing chromium, zirconium and copper) mast which is easily oxidized and difficult in adding element zirconium by utilizing the electromagnetic stirring function and through the tight coverage of a covering agent, and the technology is very simple.

Description

technical field [0001] The invention relates to a process for preparing a chromium-zirconium copper alloy wire rod, in particular to a non-vacuum short-flow process for preparing a chromium-zirconium alloy wire rod, which belongs to the technical field of nonferrous metal processing. Background technique [0002] Due to the high strength and electrical conductivity of chrome-zirconium copper alloy, its rod-shaped wire products are widely used in electronics, electric power, automobile, light industry, transportation and other industries, and have broad market application prospects. However, since Zr is easily oxidized and burned in the atmosphere, it is difficult to produce chromium-zirconium-copper alloy wire rods without vacuum. The non-vacuum preparation and short-process production method of the alloy can achieve the goals of energy saving, consumption reduction, and environmental protection, and has excellent social benefits; the chromium-zirconium copper alloy wire rod...

AI Technical Summary

Problems solved by technology

Completely closed non-vacuum melting and casting equipment and processes have the following defects: ①It 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. Since these windows are It is relatively small, so it is not conducive to a large number of continuous feeding and observation; ②It cannot achieve more continuous preparation, and most non-vacuum melting chromium-zirconium copper alloys cannot achieve continuous production, because the equipment is usually melted in one furnace When casting a furnace, it is necessary to stop and open the furnace cover to add materials; ③Without melt stirring equipment, it is impossible to obtain an alloy with a relatively uniform and stable composition
