Embodiment 1

[0046] A rare earth oxygen-free copper-based alloy with tellurium, manganese and stilbium added to the copper. The capacity of the industrial frequency furnace for melting, heat preservation and lead rod production is 300kg, and the copper in the furnace is 300kg when it is full. After the copper temperature in the melting furnace reaches 2050°C, add additives gradually with a feeder, adding 0.15kg of tellurium, 0.03kg of manganese, and 0.15kg of stilbium into one furnace. At the same time, use green tree sticks to continuously stir mechanically for 20 minutes, and then use six lead rods in the holding furnace to start using crystallizer lead rods according to the process. Copper-based alloy rods are continuously drawn up to produce 800kg per hour, power frequency melting furnace Copper and additives are also added continuously. Copper and tellurium, manganese and stilbium are added sequentially, and the speed is kept uniform and synchronous. Add copper 800kg, tellurium 0.4k...

Abstract

The invention discloses an oxygen-free copper-based alloy and a production process thereof. The oxygen-free copper-based alloy is obtained by adding 0.05w%-0.2w% of tellurium, 0.01w%-0.02w% of manganese and 0.05W%-0.10W% of boron. The production process of the oxygen-free copper-based alloy comprises the production steps of electrolytic copper cleaning, shearing, melting, heat-preserving and guide rod producing, wherein in the melting and heat-preserving steps, an additive is added when a temperature of molten copper is 2050 DEG C-2100 DEG C. A layer of ash wood covers the surface of the molten copper to isolate oxygen in air. Green tree strips are used for mechanically stirring or electromagnetic rods are used for electromagnetically stirring, the molten liquid is uniformly mixed. And mixing and stirring time is 20-30 minutes. The oxygen-free copper-based alloy produced by the production process disclosed by the invention has the characteristics of being high in resistance to oxidation, high in strength and high in electric conductivity at high and low temperatures.

Description

technical field [0001] The invention relates to an oxygen-free copper-based alloy and a production process thereof, in particular to an oxygen-free copper-based alloy used in motors, electrical appliances and power distribution equipment and a production process thereof. Background technique [0002] Copper has excellent properties such as good electrical conductivity, thermal conductivity, corrosion resistance, and weldability. It is a widely used metal material and one of the main materials for conductive materials. my country's copper metallurgical industry and copper processing industry wire and cable conductive materials mainly use industrial pure copper (copper) T 1 , T 2 , they all contain more impurities (see the table below). [0003] [0004] Impurities in copper will affect the conductivity. Oxygen (200ppm) and sulfur in copper form brittle phase oxide Cu with copper 2 O, Cu 2 S, not only reduces the conductivity of copper, but also makes copper brittle, c...
