Wire annealing process and device thereof

Abstract

The invention relates to the technical field of wire annealing, in particular to a wire annealing process and a device thereof, the wire annealing process mainly comprises three working procedures of heating treatment in a high temperature annealing region, cooling treatment in a steam cooling region and liquid water coating and cooling treatment in a liquid water coating and cooling region, wherein steam in the steam cooling region is low-temperature steam generated by a built-in steam generator, thereby realizing high cooling efficiency, having no problem of condensate and being applied in annealing of a variety of wires; furthermore, due to the working procedure of the liquid water coating and cooling treatment, the wire annealing process can not easily complete the wire cooling, but also better complete the tasks of coating of an antioxidant, coating a booster flux, cleaning the booster flux and the like. Therefore, the wire annealing process and the device thereof can avoid the oxidation of annealed wires, improve the performance and the quality stability of the wires after annealing, further realize the perfect coating of the antioxidant and the pretreatment of tin plating, have good energy-saving effect and be applied in the annealing of a variety of wires.

Description

Technical field: [0001] The invention relates to the technical field of wire rod annealing, in particular to a wire rod annealing process and a device thereof. Background technique: [0002] Continuous wire annealing furnace is widely used in the annealing process of enameled wire, tinned wire, bare copper wire and other wire rods. Taking enameled wire and tinned wire as an example, annealing process is usually provided before enameled wire is painted or tinned wire is tinned. To facilitate painting or tinning. For bare copper wires, it is usually required to coat the surface of the wire with antioxidants during annealing. The traditional method is to add water-soluble antioxidants to the water-sealed water tank at the exit of the annealing furnace, so water-sealed water-sealed water tanks must be used regardless of the thickness of the wires. The annealing furnace and the water-sealed water tank not only bring about the problems caused by the drying and drying of the atta...

AI Technical Summary

Problems solved by technology

However, its water-sealed water tank brings drying and drying problems, which not only consumes extra electric energy, but also brings more hidden dangers in quality, and the resistance of the guide wheel in the water severely limits the production speed of wire rods.

In addition, the cooling speed of the water-sealed annealing process is too fast to adapt to materials with rapid cold hardening effects such as steel, and the annealing effect on wires such as copper-clad steel is not good.
