Abstract

The invention discloses a method for first continuously annealing nonferrous metal wires in an on-line mode and then hard drawing the nonferrous metal wires. The method comprises the following steps of wire putting, on-line continuous middle annealing, drawing processing and wire arraying and collecting step. The invention has the advantages of putting forward a fire-new annealing process route and filling up the blank of the tinily drawing on-line continuous middle annealing process. Compared with the prior on-line continuous finished product heavy current annealing process used in the cable industry, the method can simplify the structure of equipment, reduce cooling water flow, install heat insulation facilities and leave out two process steps of external connection of protective gas and dryness of compressed air. Meanwhile, because non-contact annealing is adopted, the annealing quality is ensured. The device is easy to operate and maintain, has low manufacturing and use cost and can be applied to the whole cable industry, especially small and medium-sized enterprises. The on-line continuous middle annealing method is a novel basic processing technology capable of saving energy and water, improving quality and lowering cost in the cable industry.

Description

technical field [0001] The invention relates to a method for heat-treating non-ferrous metal wires hardened by cold work; in particular, after the non-ferrous metal wires are cold-drawn to produce hardening phenomenon, in the process of continuing cold-drawing process, online continuous heat treatment is carried out before continuous cold-drawing processing process methods and equipment. Background technique [0002] Non-ferrous metal wires are usually produced by cold drawing process. This process usually produces cold work hardening, which increases the difficulty of subsequent processing of finished products, or makes it difficult for non-ferrous metal wire and cable products to obtain excellent comprehensive mechanical properties, or makes non-ferrous metal wires and cables difficult to obtain. The metal wire loses its plasticity and cannot be further processed. In order to avoid this phenomenon, heat treatment is usually used to eliminate the cold work hardening phenome...
