Embodiment Construction

[0009] The present invention is further described in conjunction with the examples. The present invention is an improvement on the basis of the existing all-scrap copper continuous casting and rolling copper rod process. , Casting machine slab, traction slab processing, rolling mill automatic rolling, continuous rolling, copper rod cooling, plum blossom coiling, inspection and packaging, the change is to set the copper water outlet of the reverberatory furnace on the back of the reverberatory furnace , so that the distance of the launder is reduced from the existing 8-10m to 5-6m. Due to the shortened distance of the launder, the high-temperature copper production is changed to the low-temperature copper production, which is conducive to improving the quality of copper while reducing energy consumption; Increase the volume of the billet to make the existing copper billet 1800mm 2 The cross-sectional area is changed to 2320-2340mm 2 cross-sectional area, casting time is shorte...

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...
