Knitting wire (English name: card wire) is a kind of middle and high carbon steel wire used for knitting fiber (cotton, wool, hemp, silk, chemical fiber) in textile industry. General points metal needle cloth and elastic needle cloth steel wire two. The steel wire is a round steel wire of carbon structure with 0.5% ~ 0.7% C in annealed condition, which is rolled flat, made and hardened by the user. The common cross section shapes of elastic needle cloth steel wire are round, triangle and flat, in addition, there are double convex and oval. The diameter of round steel wire is 0.205 ~ 1.215 mm and the surface is galvanized. In addition to the tensile strength to meet the requirements, the steel wire should be straight, elastic and brittle, the product should be straightness, brittleness and elasticity inspection. Steel wire is made of carbon structural steel containing 0.55%C and 0.65%C and manganese. The content of sulfur and phosphorus in steel should be %26le. 0.035%.
The production process
In the production of special-shaped steel wire, the wire rod is first drawn into a round wire blank, and then pulled into the required section shape by the method of roller drawing (see roller die drawing) in the finished passage. Triangular steel wire with three rollers pull; Flat wire is drawn by two rollers. The heat treatment process of the finished product must be reasonably selected to achieve the specified performance of the elastic needle cloth steel wire. Generally, quenching (heating temperature is 860 ~ 900ºC) and moderate temperature (heating temperature is 460 ~ 500ºC) are used to temper the troisite structure. Due to the small size of the steel wire, the decarbonization and oxidation of the steel wire should be prevented during quenching. The choice of quenching medium should not only ensure that the steel wire can be quenched thoroughly, but also be conducive to galvanizing and avoiding brittle fracture during continuous operation. Polyvinyl alcohol with a concentration of 0.5% ~ 2% and a temperature of 52ºC is generally used as quenching medium. The tempering temperature should be uniform and sufficient time should be allowed.
