Embodiment Construction

[0020] The present invention will be further explained below in conjunction with specific embodiments. Apparently, the described embodiments are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0021] The invention provides a high-efficiency continuous casting and rolling production process for special-shaped copper rods, which includes the following steps:

[0022] S1. Smelting: put the electrolytic copper raw material in a reflective melting furnace for melting and refining. The refining process includes adding coke for the first refining and slag removal, and then refining twice with pure nitrogen and powdery slagging agent. Blast the molten copper with a blast pressure of 0.38MPa;

[0023] S2. Insulation treatment: add purification flux t...

Abstract

The invention discloses an efficient continuous casting and continuous rolling production technology for a special-shaped copper rod. The efficient continuous casting and continuous rolling productiontechnology includes the following steps that smelting is conducted, heat insulation treatment is conducted, continuous casting treatment is conducted; copper blank heat rolling is conducted; the rolled special-shaped copper rod is cooled and blown to be dry through a vacuum anti-oxidation tube and a cooling groove, and a coloring treatment technology is conducted on the special-shaped copper rod;and wax is rapidly and evenly smeared on the surface of the special-shaped copper rod, then rod winding is conducted, and afterwards, packaging is conducted. By means of the technology, in the process of smelting electrolytic copper raw materials, coke, pure nitrogen and a powdery slagging agent are used for conducting multiple refining, and impurities in copper liquid can be removed more thoroughly; in the heat insulation treatment process, degassing and deslagging are conducted at the same time, and purity of the copper liquid can be further ensured; in the continuous casting treatment process, ultrasonic treatment is used, the continuous casting effect of the copper liquid can be better, and mass distribution of the copper blank obtained after continuous casting can be more uniform; the continuous casting and continuous rolling technology is used for producing the special-shaped copper rod, and the production efficiency is higher.

Description

technical field [0001] The invention relates to the technical field of copper rod production, in particular to a high-efficiency continuous casting and rolling production process for special-shaped copper rods. Background technique [0002] Copper rods are generally produced with electrolytic copper, and their resistivity is lower than that of low-oxygen copper rods. Therefore, in the production of products with strict resistance requirements, oxygen-free copper rods are more economical; the manufacture of oxygen-free copper rods requires high-quality raw materials; Oxygen copper rods are more superior to draw copper wires with a diameter of <0.5mm, and 6MM oxygen-free copper rods are used to produce copper flat wires. [0003] Due to the different processes for producing copper rods, the oxygen content and appearance of the produced copper rods are different. The copper rods produced by Shangyin are properly crafted and the oxygen content is below 20ppm, which is called...
