Copper wire stretching and annealing process

Abstract

The invention relates to a copper wire stretching and annealing process. The process comprises the steps of straightening copper wires to be processed horizontally; cleaning and drying the copper wires; straightening the copper wires vertically; feeding the copper wires into an annealing device for annealing; feeding the annealed copper wires into a quenching device; feeding the copper wires into a drying device for drying; conducting primary stretching pretreatment on the dried copper wires; conducting primary stretching; conducting secondary stretching pretreatment on the copper wires subjected to primary stretching; and conducting secondary stretching on the copper wires subjected to secondary stretching pretreatment, and accordingly realizing repeated and continuous stretching. The copper wire stretching and annealing process is good in reliability and implementation. Continuous induction annealing can be realized. Work hardening of the copper wires is eliminated. The plasticity of the copper wires is recovered. Conditions are provided for subsequent continuous stretching. The production requirements for super-long copper wires are met.

Description

technical field [0001] The invention belongs to the field of annealing, and in particular relates to a copper wire drawing annealing process. Background technique [0002] At present, the traditional intermediate annealing process uses electric heating radiant tubes or gas heating, which cannot meet the production requirements of ultra-long brass condenser tubes, and cannot achieve continuous stretching. [0003] Therefore, proposing a copper wire drawing and annealing process is the subject to be studied by the present invention. Contents of the invention [0004] In order to solve the shortcoming of low intelligence in the prior art, a copper wire stretching annealing process is provided, and a stretching device and an annealing device are prepared in advance; the stretching device includes a stretching pretreatment device, a stretching device, a secondary stretching pretreatment device and a secondary stretching device; the annealing equipment includes a horizontal str...
