Production method of galvanized steel wire

Abstract

The invention discloses a production method of a galvanized steel wire. A solvent method is mainly adopted for steel wire hot galvanization at present, and because an acid washing process is adopted, equipment and a factory can be corroded, the health of workers in the environment for a long time is damaged, and the energy consumption of the method is also higher. In order to overcome the defects, the invention provides the production method of the galvanized steel wire, which sequentially comprises the processes of wire unwinding, mechanical stress elimination, ultrasonic compound washing, water washing, plating assistance, hot-dip plating and wire winding. In the method, a plurality of steel wires are synchronously and continuously galvanized on line at the same speed, the traction force of the whole equipment is provided by wire winding equipment without other powers, and a roller is used in the wire arranging process of the steel wires. The production method is simple, a pluralityof galvanized steel wires can be synchronously and continuously produced at the same speed, and the production method has high efficiency, low energy consumption, time saving, labor saving and short period, avoids the possibility that the steel wire is rusted again, and has no acid washing, less environment pollution, low cost and good quality of the galvanized steel wire.

Description

technical field [0001] The invention relates to the metallurgical industry, in particular to the plating of metal materials. Background technique [0002] Hot-dip galvanizing of metal products is one of the most basic and effective anti-corrosion processes. Metal products that can be hot-dip galvanized include steel wire, plate, steel coil, steel pipe, structural parts and fasteners, among which steel wire is an important category. [0003] At present, the hot-dip galvanizing of steel wire mainly adopts the solvent method, which is a low-speed and simultaneous hot-dip galvanizing process for multiple steel wires. This technique has the following problems: one, due to the adoption of the pickling process, the hydrochloric acid or sulfuric acid used has great volatility and corrosiveness, which will corrode equipment and workshops, and damage the health of workers who have been in this type of environment for a long time; 1. Annealing needs to heat the steel wire, and after ...

AI Technical Summary

Problems solved by technology

There are following problems in this technique: one, due to adopting the pickling process, the hydrochloric acid or sulfuric acid adopted have very large volatility and corrosivity, can corrode equipment and workshop, damage the health of the staff who is in this type of environment for a long time; 1. Annealing needs to heat the steel wire, and after the annealing is completed, the steel wire needs to be cooled. It is heated again during hot-dip plating, and the heat is wasted. Moreover, the multi-line low-speed simultaneous plating process is adopted, the production surface is wide, the speed is slow, the heat dissipation is high, and the energy consumption is high; three. 1. The process is complicated and the production efficiency is low; 4. Due to the existence of appeal problems, the production cost is high, the product profit is low, and the competitiveness is low
