Anti-oxidation protection device for continuous annealing of copper wire and continuous annealing device for copper wire

Abstract

The invention discloses an anti-oxidation protecting device for copper wire continuous annealing. The anti-oxidation protecting device for the copper wire continuous annealing comprises an upper base and a lower base which corresponds to the upper base. The bottom of the upper base is provided with annular cooling liquid troughs. The side part of each annular cooling liquid trough is provided with a cooling liquid inlet opening. The middle of the upper base is vertically provided with an insulation wire passing pipe which is made from an insulating wear resistant material and used for allowing a copper wire to be penetrated through. The top of the lower base is provided with annular steps which are matched with the annular cooling liquid troughs. The middle of the lower base is vertically provided with a channel used for allowing the copper wire to be penetrated through. A cone-shaped cooling liquid flow channel is formed between the top of the channel and the bottom end of the middle of the upper base. The invention further discloses a copper wire continuous annealing device. The copper wire continuous annealing device comprises a pre-heating section, a high temperature annealing section and a cooling drying second, wherein the pre-heating section, the high temperature annealing section and the cooling drying second are arranged in the heading direction of the copper wire in sequence. The high temperature annealing section is vertically arranged, and an outlet opening of the high temperature annealing section is provided with the anti-oxidation protecting device for the copper wire continuous annealing.

Description

technical field [0001] The invention relates to a continuous annealing device for copper wire, in particular to an anti-oxidation protection device for continuous annealing of copper wire and a continuous annealing device for copper wire. Background technique [0002] Copper wire drawing machine is a widely used mechanical equipment in the wire and cable manufacturing industry. The wire drawing machine is a kind of equipment that plastically deforms the copper wire through the gradually decreasing die hole under a certain tension at room temperature, so that the cross section of the copper wire is reduced into a copper wire and the length is increased. During the drawing process of the copper wire, due to the plastic deformation of the wire, the grains of the internal structure of the wire are extruded, deformed, and dislocated, and each grain is also elongated and twisted along the deformation direction. This situation is called cold work hardening. The direct performance ...

AI Technical Summary

Problems solved by technology

[0004] Copper wire is easy to oxidize at high temperature. In order to prevent copper wire from oxidizing, the high-temperature annealing section must be in an oxygen-free environment. Generally, external steam or nitrogen protection is used, and external steam or nitrogen protection is used. Additional gas must be added outside the continuous annealing wire drawing machine. generating equipment, which undoubtedly increases production energy consumption

Moreover, there is no energy-saving annealing oxidation protection device for continuous annealing of copper wire at present.
