Embodiment Construction

[0022] The present invention improves the existing production process of copper-clad aluminum or copper-clad aluminum-magnesium wire. The whole process line is the same as that of the prior art, including starting from the acceptance of raw materials, successively passing through intermediate drawing and rough drawing, and then using the present invention for annealing. process, annealing the raw silk under the protection of hydrogen in an anti-oxidation atmosphere.

[0023] Set the annealing temperature in the range of 350-450°C, which can be specifically selected as 350°C, 360°C, 370°C, 380°C, 400°C, 420°C or 440°C, etc.; the hydrogen pressure is 0.3-1.0MPa, which can be specifically selected as 0.3 MPa, 0.4MPa, 0.5MPa, 0.6MPa, 0.7MPa, 0.8MPa, 0.9MPa or 1.0MPa; the annealing time is 1.5 seconds to 3.5 seconds, which can be selected as 1.5 seconds, 1.6 seconds, 1.8 seconds, 2 seconds, 2.2 seconds , 2.5 seconds, 2.8 seconds, 3.0 seconds, 3.2 seconds or 3.5 seconds etc.

Abstract

The invention discloses an annealing technique and equipment of copper-in-aluminium or copper-in-aluminium magnesium yarn manufacturing course, which is characterized by the following: setting box-typed electric heating annealing furnace with furnace pipe in the annealing furnace along two ends of longitude furnace wall; setting the yarn inlet on one end of furnace pipe on the annealing furnace with yarn outlet as the other end; guiding yarn on the line shaft into furnace pipe through wheel; drawing the yarn out of furnace pipe; connecting yarn outlet on one end of furnace pipe and hydrogen source through three-way adaptor; setting the yarn inlet as igniting end; forming anti-oxidant in the furnace pipe; improving anti-extending strength and extending rate.

Description

technical field [0001] The invention relates to a production process and equipment for wires, more specifically a production process and equipment for copper-clad aluminum and copper-clad aluminum-magnesium wire. Background technique [0002] Copper-clad aluminum and copper-clad aluminum-magnesium are replacement products of pure copper wires. They mainly adopt the production process of "coating welding and drawing method". Passes of drawing and heat treatment are made to meet the technical requirements of the customer's wire diameter and mechanical and electrical properties. A firm metallurgical bond is formed between the copper layer and the aluminum rod core wire, and its surface is required to be bright, round and free of defects, so that the copper-clad aluminum wire has the characteristics of low density of aluminum and good electrical conductivity of copper. When this kind of bimetal composite wire is used in the inner conductor of coaxial cable, it not only has high...
