Broken wire is the iron bright wire, fire wire, galvanized wire, coated wire, paint wire and other metal wire, wire factory according to customer requirements straightening fixed length cut, with easy transportation, easy to use characteristics, widely used in the construction industry, handicrafts, daily civil and other fields. There is no limit on length, pack as required. Anneal wire also known as black oiled wire, black anneal wire, fire wire, black iron wire. Compared with cold drawing, black annealed wire is more economical as raw material for nails.
Features: strong flexibility, good plasticity, widely used process: selection of high-quality low-carbon raw materials, after wire drawing, annealing processing, soft and strong tensile resistance. Finished products coated with anti-rust oil, not easy to rust, according to customer requirements into bundles, each bundle 1-50kg, can also be made into U-shaped wire, broken wire, etc., inner plastic outer hemp packaging, mainly used for binding wire, construction wire, etc.
Usage: Black wire is widely used in construction industry, handicrafts, woven silk screen, product packaging, park and daily life used in binding wire. Low carbon steel wire diameter 0.265 ~ 1.8mm, tensile resistance 300 ~ 500MPa, elongation 15% packaging reel or reel. Annealing wire is drawn after the low carbon steel wire into the annealing tank or annealing furnace, high temperature heating to the appropriate temperature, and then slowly cooling, after taking out can achieve the purpose of annealing.
Annealing is to restore the plasticity of iron wire, improve the tensile strength of iron wire, hardness, elastic limit, after annealing wire called annealing wire. Annealing iron wire in the production process, to ensure the quality of finished wire, wire has a certain strength, appropriate degree of hardness, annealing process is very important. The annealing temperature is between 800 ℃ and 850℃, and the length of furnace tube is lengthened appropriately to keep heat for a long time.
