A copper rod coating device and a copper rod coating method using the same

Abstract

The invention relates to a copper bar coating device and a copper bar coating method using the same. The device comprises a shell part, a frame and a copper liquid containing part; the shell part comprises a shell and a coil, the shell is of a hollow column with an opening in the upper portion, and the coil spirally extends in the axis direction of the inner circumference of the shell and is inlaid into the shell; the frame is fixed to the outer side of the shell in a surrounding manner; the copper liquid containing part comprises a container and a connecting plate, the container is a hollow column with the closed lower portion and the opened upper portion, the connecting plate is arranged at the bottom of the container, the container is concentrically placed on the connecting plate in theinner circumference of the shell, and a runner allowing copper liquid to flow into the container extends to penetrate the shell part and the side wall of the container; a through hole allowing a corerod to penetrate is arranged at the bottom of the copper rod coating device and is concentric with the container, and in the core rod moving process, the copper liquid is coated to the surface of thecore rod. According to the copper bar coating device and the copper bar coating method, coil exposure is avoided, the coil cannot be damaged even thorough copper leakage occurs, and the heating effect is good. The position between the outer wall of the container and the inner wall of the shell is filled with ceramic fiber cotton, and the effects of heat preservation, heat isolation and crucible fixing are achieved.

Description

technical field [0001] The invention relates to the field of copper rod manufacturing, in particular to a copper rod coating device and a copper rod coating method using the same. Background technique [0002] Dip-coating method Oxygen-free copper rod production line The casting rod formation process mainly includes that the copper liquid in the holding furnace enters the crucible, the core rod is drawn through a wire drawing machine, and the oxide layer is removed by a peeling device, and then passes through the crucible, and the surface of the core rod absorbs heat instantly and covers the copper liquid A casting rod coated with copper liquid is formed, and the casting rod is pressed through a cooling chamber and a rolling mill to form a finished copper rod. At present, the commonly used crucible is composed of mica plate, ceramic fiber cotton, graphite crucible, heating coil, etc. The copper liquid enters the crucible, and the core rod absorbs heat to coat the copper liqu...

AI Technical Summary

Problems solved by technology

[0003] 1) Due to the high ambient temperature of the crucible and the limitation of the heat resistance strength of the mica plate, the mica plate is seriously damaged and the service life is low;

[0004] 2) The copper liquid enters the crucible through the holding furnace, which is prone to liquid leakage. The copper liquid and the heating coil condense and cannot be separated, causing the coil to be damaged and cannot be reused;

[0005] 3) Due to the splicing and installation of mica boards, there are many screws and other fixings, the disassembly and filling are cumbersome, and the production efficiency is reduced;

[0006] 4) While relying on the coil to generate a magnetic field to heat the copper liquid, it will also cause damage to the outer frame of the coating chamber, especially the contact points such as connecting bolts and welding points will burn red and be damaged
