Embodiment Construction

[0021] 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.

[0022] 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 relates to an annealing device applied to the production of a copper clad aluminum wire or a copper clad aluminum magnesium wire, which is characterized in that: the annealing device is provided with a box-type electric heating annealing furnace; a furnace tube is arranged in the annealing furnace and passes through the furnace walls at two ends of the annealing furnace longitudinally; one end of the furnace tube outside the annealing furnace is a wire inlet, while the other end is a wire outlet; a raw wire on a paying out shaft is guided into the furnace tube from the wire inlet through a guide wheel and is guided out of the furnace tube from the wire outlet; the furnace tube on one end where the wire outlet is connected with a hydrogen source through a gas separating cylinder by a tee joint so that the hydrogen is filled into the furnace tube from the tee joint; the wire inlet is set as an ignition port; and anti-oxidation atmosphere is formed in the furnace tube. The annealing device can greatly improve the tensile strength and the tensile stretch of the copper clad aluminum wire or the copper clad aluminum magnesium wire.

Description

[0001] This application is a divisional application with the application number 200610098120.5, the application date is November 29, 2006, and the invention name is the annealing process and equipment applied to the production of copper-clad aluminum or copper-clad aluminum-magnesium wire. technical field [0002] The invention relates to production equipment for wires, more specifically a production equipment for copper-clad aluminum and copper-clad aluminum-magnesium wires. Background technique [0003] 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, rou...
