Abstract

The invention discloses a tellurium copper alloy material for the electric power industry and a method for preparing the same. The method is characterized by comprising the following steps: gradually adding 99.55 to 99.89 weight percent of industrial pure copper after a molten channel of a power-frequency induction furnace is melted; raising the temperature of a copper liquid to between 1,190 and 1,230 DEG C after solid state copper is melted down, and covering the copper liquid with charcoal to keep the temperature; enwrapping 0.1 to 0.4 weight percent of pure tellurium, and pressing the pure tellurium to the bottom of a power-frequency furnace close to a molten channel opening at a furnace temperature of between 1,190 and 1,230 DEG C; adding 0.01 to 0.05 weight percent of microelement into a tellurium copper alloy liquid after 50 to 80 minutes; finishing the smelting of the tellurium copper alloy liquid after 15 to 30 minutes; reducing the furnace temperature to between 1,150 and 1,180 DEG C; pouring the alloy liquid into a graphite crystallizer for crystallization; towing a cast ingot by using the prior method and sawing the cast ingot into short cast ingots with specific lengths; sampling the short cast ingots to test the content; and packaging the short cast ingots into finished products.

Description

technical field [0001] The invention relates to a tellurium-copper alloy material used in the electric power industry and a preparation method thereof, belonging to the field of preparation of new alloy materials. Background technique [0002] Because tellurium copper alloy has excellent high conductivity, arc resistance, good strength plasticity and cold and hot processing performance, it can be widely used in IT, electronics, electrical appliances, cables and other high-end industrial sectors. In the past, the process and equipment used to solve the problem of adding tellurium and additive elements that have a low density and do not form a solid solution with copper and homogenizing them in copper are relatively complicated. For example, the current process flow is: tellurium-copper master alloy melting and casting---vacuum melting and casting of low-melting element master alloy---500Kg medium frequency induction furnace melting---1000Kg power frequency induction furnace i...
