Method for producing continuous casting, and tandem rolling copper rod from all of copper scrap

Abstract

A conticasting-tandem rolling technology for manufacturing copper rod with rejected copper material features that the molten copper top is arranged on the back of reflection furnace for shortening the flow launder, the molten copper is tapped at lower temp for improving its quality, the volume of cast strand is increased for shortening the casting time and decreasing electric consumption, the 14 passes of rolling frame is decreased to 12 passes for higher quality, and gas instead of coal is used as fuel for less pollution.

Description

technical field [0001] The invention relates to a method for producing all-copper scrap continuous casting and rolling copper rods, belonging to the technical field of conductive material manufacturing. Background technique [0002] In the manufacture of wires and cables, copper wires are needed as conductors, and copper wires need to be processed with copper rods through corresponding processes. In the 1990s, foreign countries successfully developed a production line for continuous casting and rolling copper rods of all scrap copper, which saves the production line. The process of electrolytic copper, the conductivity of copper rods and other indicators have reached the relevant standards, which has reduced the production cost of copper rods. At the beginning of this century, China has also developed a new type of all-scrap copper continuous casting and rolling production line in my country to produce low-oxygen bright copper. Rod, the performance process is not reasonable, o...

Problems solved by technology

[0003] The purpose of the present invention is to provide a production method for continuous casting and rolling copper rods of all scrap copper, which solves some unreasonable problems in the existing production process of copper rods for continuous casting and rolling of all scrap copper, which leads to high product quality. Less than the national standard requirements, low precision and other deficiencies, the product quality meets the standard requirements, the end-break rate for drawing wires is low, and labor intensity and production costs are reduced.
