What Is Wire Cloth?

Card clothing steel wire is a medium and high carbon steel wire for the manufacture of carded fibers (cotton, wool, linen, silk, chemical fiber) in the textile industry.

Card clothing wire is

Generally divided into two types of metal clothing and elastic clothing. The metal card clothing steel wire is an annealed carbon structural steel round steel wire containing 0.5% to 0.7% C, which is rolled, flattened and hardened by the user. The common cross-sectional shapes of elastic clothing wire are round, triangular, and flat, as well as biconvex and oval. The diameter of round steel wire is between 0.205 and 1.215 mm, and the surface is galvanized. Except that the tensile strength should meet the requirements, the steel wire should be straight, elastic and not brittle, and the product should be checked for straightness, brittleness and elasticity. The 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 the steel should be% 26le; 0.035%.

When producing special-shaped steel wire, the wire rod is first drawn into a round wire blank, and then the roller is drawn (see roll die drawing) in the finished product pass to obtain the required cross-sectional shape. Triangular wire is drawn by three rolls; flat wire is drawn by two rolls. To achieve the required performance, the elastic card clothing steel wire must reasonably select the finished product heat treatment process. Generally, quenching (heating temperature is 860-900 ° C) and intermediate temperature (heating temperature is 460-500 ° C) are used to obtain tempered bainite structure. . Due to the small wire size, decarburization and oxidation of the wire should be prevented during quenching. The selection of the quenching medium should not only ensure that the steel wire can be hardened, but also be conducive to galvanizing and no brittle fracture during continuous operation. Generally, polyvinyl alcohol with a concentration of 0.5% to 2% and a temperature of 52 ° C is used as the quenching medium. Temper the temperature uniformly and allow sufficient time.
