Cold wire drawing in building materials used more, cold wire drawing test standards are also different.Cold wire drawing high strength, can be used in many ways, with much is the prestressing tendons.Do not require plastic, only the strength of the occasion, you can use such steel.Cold wire drawing is a kind of metal cold working.The raw material is a wire rod, which is what we often say.After peeling and a series of processes to produce products.Is the common wire.Ordinary round, let it through a little smaller than its diameter hole forcibly pulled over, the round diameter will be smaller, the length will be elongated, repeat this process, the round will be further smaller.This plastic deformation after the steel hardness will increase, the plastic will basically disappear.
Annealed Wire has good elasticity and flexibility, can control its hardness in the annealing process, made of high-quality wire, mainly used in the construction industry for bundled wire and tie line.Softer than ordinary black wire, more flexible, uniform softness, consistent color.Annealed Wire is made of low carbon steel cold drawing, heating, constant temperature, thermal insulation and other processes from a soft wire products.Iron wire according to different purposes, the composition is not the same, it contains iron, cobalt, nickel, copper, carbon, zinc, and other elements.The hot metal billet rolling into a 6.5 mm thick steel strip is wire rod, and then into the drawing device pulled into a different diameter of the line, and gradually reduce the diameter of the drawing disk, cooling, annealing, coating and other processing technology made of a variety of different specifications of wire.
I hope you can introduce the above information, you can clearly know the difference between cold wire drawing and annealed wire, and can be applied through a reasonable cold wire drawing and annealed wire.Whether you want to buy cold Wire drawing and annealing wire, or want to know more about cold wire drawing and annealing wire, welcome to contact our company.
