Steel wire heat treatment-electrolysis-phosphorization continuous production line equipment and process

Abstract

The invention provides steel wire heat treatment-electrolysis-phosphorization continuous production line equipment, which is composed of a pay-out unit, a heat treatment system, a steel wire surface cleaning system, an electrolytic phosphorization system and a take-up, wherein the pay-out unit, the heat treatment system, the steel wire surface cleaning system, the electrolytic phosphorization system and the take-up are orderly mounted and arranged into the continuous production line equipment. After a steel wire is subjected to heat treatment and surface treatment, the steel wire in an electrolysis-phosphorization fluid is electrified; the steel wire serves as a cathode and an inert conductor serves as an anode; the cathode and the anode have a hydrolysis reaction; then zinc ions and phosphate ions in the phosphorization fluid are jointed together under an alkaline condition to form zinc phosphate crystals (Zn3(PO4)2) on the surface of the steel wire. According to the electrolysis-phosphorization process, the thickness of a phosphorized film on the steel wire can be controlled by controlling the current density of the steel wire; the phosphorization speed is high; no phosphorized residue is generated in the electrolysis-phosphorization process.

Description

technical field [0001] The invention relates to a steel wire heat treatment electrolytic phosphating continuous production line equipment and technology, in particular to a kind of equipment and production technology for heat treatment and surface treatment before steel wire drawing, belonging to the technical field of metal product processing equipment and technology. Background technique [0002] With the continuous development of my country's market economy, the competition in the metal products industry is becoming increasingly fierce. Many well-known domestic metal products companies are improving their competitiveness by saving energy and reducing consumption and increasing elongation. In the metal products industry, the traditional medium-temperature or high-temperature impregnation and phosphating technology after heat treatment has its own shortcomings, such as large slag production, high energy consumption, and long phosphating time. As an advanced phosphating tech...
