Steel wire heat treatment electrolytic phosphating continuous production line equipment and process

Abstract

The invention relates to a continuous production line equipment of electrolytic phosphating for heat treatment of steel wire, which is composed of a wire unwinding device, a heat treatment system, a steel wire surface cleaning system, an electrolytic phosphating system and a wire take-up device arranged in sequence to form a continuous production line equipment. After the steel wire is heat-treated and surface-treated, the steel wire in the electrolytic phosphating solution is energized, the steel wire is used as the cathode, and the inert conductor is used as the anode, and a hydrolysis reaction occurs. Under alkaline conditions, zinc ions in the phosphating solution combine with phosphate ions Together, zinc phosphate crystals (Zn 3 (PO 4 ) 2 ), the electrolytic phosphating process controls the thickness of the phosphating film on the steel wire by controlling the current density of the steel wire, the phosphating speed is fast, and no phosphating slag is generated during the electrolytic phosphating 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...
