Embodiment Construction

[0018] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0019] A kind of processing technology of tin-coated copper wire, this processing technology comprises the following steps:

[0020] Step 1. Material preparation: Prepare dry and clean copper scrap, copper ingot, magnesium ingot and silicon ingot, pour the copper scrap and copper ingot into the melting furnace, flatten the convex peaks exposed to the liquid surface with a rake, and stir with a rake Melt, after all the furnace materials are melted, add other waste materials such as corners, and press them into the melt while adding waste materials, and no waste materials should be exposed to the copper liquid when igniting;

[0021] Step 2, primary refining: after all the charge is melted, use N2 and refining agent to carry out degassing and primar...

Abstract

The invention discloses a processing technology of a tin-coated copper wire. The processing technology comprises the following steps of: preparing materials: preparing dry and clean copper material waste, copper ingots, magnesium ingots and silicon ingots, pouring the copper material waste and the copper ingots into a smelting furnace, leveling convex peaks exposed out of the liquid level by usinga rake, stirring the melt by using the rake, adding other wastes such as corners after the furnace burden is completely molten, pressing the wastes into the melt while adding the wastes, and not exposing the wastes out of the copper liquid during ignition; performing primary refining: performing degassing and primary refining by using N2 and a refining agent after the furnace burden is completelymolten; and performing secondary slagging-off: removing the furnace slag. The processing technology of the tin-coated copper wire disclosed by the invention is excellent, and the processed product ishigh in quality.

Description

technical field [0001] The invention belongs to the technical field of copper wires, in particular to a processing technology of tin-coated copper wires. Background technique [0002] In life, copper wires are used as conductors. Good electrical conductivity, widely used in the manufacture of wires, cables, brushes, etc.; good thermal conductivity, often used to manufacture magnetic instruments and instruments that must prevent magnetic interference, such as compass, aviation instruments, etc.; excellent plasticity, easy to hot press and Cold pressure processing can be made into copper materials such as tubes, rods, wires, strips, strips, plates, and foils. There are two types of pure copper products: smelted products and processed products; [0003] However, the existing power line processing technology is not energy-saving, and the quality of the finished product needs to be improved. Therefore, we propose a processing technology for tin-coated copper wire. Contents of...
