Degreased tire bead wire processing method

Abstract

The invention discloses a degreased tire bead wire processing method. The method comprises the following steps of (1) paying-off; (2) straightening; (3) mixed degreasing; (4) tempering; (5) water washing; (6) surface treatment; (7) water washing; (8) alloy combination; (9) water washing; (10) neutralizing; (11) water washing; (12) hot water washing; (13) drying; (14) oil coating; (15) wind-up; and (16) cooling. By means of the method, the strict requirements of foreign customers for high torsion, high elongation and high strength of tire bead wires of high-performance radial tires are met; the international competitiveness of domestic products is improved; the progress of the industry is led to and promoted; and the transformation, upgrading and scientific and technological innovation of the industry are promoted.

Description

Technical field [0001] The invention relates to the technical field of bead wire processing, in particular to a degreasing treatment method for bead wire processing. Background technique [0002] The bead wire is used in the bead part of the tire. It is one of the main skeleton materials of the tire. It is used to make the tire bead wire bundle of passenger cars and other vehicles. Its function is to make the tire tightly fixed on the rim. Withstand various interaction forces between tires and rims. [0003] Bead wire is a high-performance metal wire that is coated with bronze, copper or brass on the surface of carbon round steel wire after drawing. In recent years, with my country's huge car ownership and continuous growth in the car market, the domestic bead wire market has continued to flourish. In 2006, my country produced 280 million tires and became one of the largest tire producers in the world. In that year, the national output of bead wire was about 300,000 tons. With th...

[0005] Hankook Tire is one of the top ten international tire companies and the first tire company in Korea. Its supporting car brands include international high-end car brands such as BMW and Mercedes-Benz. Hankook Tire has very strict requirements for its downstream companies. The purchase of bead wire mainly purchases high-performance bead wire from large bead wire companies such as Bekaert and Korea Korea. The strength, fatigue, and variety structure of ordinary-strength bead wires currently produced in my country cannot meet the requirements of Hankook’s high-performance radial tires. Requirements, good elongation performance, anti-oxidation, anti-corrosion, anti-aging and other properties are far behind Bekaert and other large enterprises. It is imperative for my country to develop and produce high-performance bead wire
