Integrated production method and production line for tempered tire bead steel wire

Abstract

The invention relates to an integrated production method and production line for a tempered tire bead steel wire. The production method comprises a wire rod pretreatment working procedure, a drawing working procedure, a tempering working procedure, a copper plating working procedure and a coating working procedure which are integrally and continuously performed, and single-wire single-control production from a tempered tire bead steel wire rod to a tempered tire bead steel wire finished product is achieved; online electrolytic pickling is adopted in the wire rod pretreatment working procedure, an online high-frequency tempering mode is adopted in the tempering working procedure, and an electrochemical plating mode is adopted in the copper plating working procedure. According to the integrated production method for the tempered tire bead steel wire, traditional tempering and expansion type multi-line chemical copper plating treatment working procedures are reduced, online electrolytic pickling is adopted to replace concentrated pickling, high-frequency tempering is adopted to replace lead bath tempering, and single-line electrochemical copper plating is adopted to replace expansion type multi-line chemical copper plating, so that environmental pollution points are reduced, the production efficiency is improved, the energy consumption is reduced, the number of workers is reduced, and the reliability of the product quality is improved through automatic and intelligent production.

Description

technical field [0001] The invention relates to the technical field of metal wire surface coating, in particular to an integrated production method and production line of tempered bead steel wire. Background technique [0002] Tempered tin-plated bronze bead wire is used as a reinforcing material for the rubber skeleton in automobile tires, and is one of the important raw materials for automobile tire manufacturing. Tempered tin-plated bronze bead wire can improve the rubber adhesion and rubber aging resistance of the bead wire as a rubber skeleton material, and enhance the safety and comfort of the tire. The existing bead steel wire copper plating process is mainly based on the expanded multi-head copper plating process, which is divided into four processes: rough drawing, medium wire heat treatment, medium drawing and copper plating. Specifically, 1) the first process: Coil element → unwinding → mechanical peeling → pickling and rust removal → water washing → boron coat...

AI Technical Summary

Problems solved by technology

[0003] "Pickling rust removal", "chemical pickling", "lead tempering" and "electrolytic pickling" in the above production processes have great pollution to the environment. For example, "pickling rust removal" is mostly concentrated pickling , will produce a large amount of acid mist, pollute the factory building, poor operating environment for workers, and damage human health; another example is copper-plated lead fire tempering will produce lead vapor, polluting the environment, and lead tempering uses electric heating lead, which consumes a lot of energy. The total installed capacity is up to 2000KW etc.

In actual production, the environmental protection costs required to control these pollution points are usually high, and the waste of resources is relatively serious, and the traditional copper plating is multi-head expansion, which causes large pollution, poor environment, large energy consumption, large floor space and high labor costs (a The line generally needs 20 operators)
