Broken wire is the iron bright wire, fire wire, electric galvanized wire, plastic coated wire, paint wire and other metal wire, wire factory according to customer requirements for straightening after cutting, with convenient transportation, convenient use of characteristics, widely used in the construction industry, handicrafts, daily civil and other fields. No limit on length, packaging as required. Anneal wire is also known as black coated wire, black anneal wire, fire wire, black wire. Compared with cold drawing, black annealed wire is more economical to use 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 and become, 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 wire, broken wire, plastic packaging, mainly used as binding wire, construction wire, etc..
Use: Black iron wire is widely used in the construction industry, handicrafts, woven wire mesh, product packaging, parks and daily life used in the binding wire. Material: Low carbon steel, filament diameter 0.265 ~ 1.8mm, tensile force 300 ~ 500MPa, elongation 15%. Annealing wire is drawn after the low carbon steel wire into the annealing pot 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 the wire, improve the tensile strength of the wire, hardness, elastic limit, etc., after annealing wire called annealing wire. Annealing wire in the production process, to ensure the quality of finished wire, wire with a certain strength, the appropriate degree of soft and hard, annealing process is very important. The annealing temperature is between 800 ℃ and 850℃, and the length of the furnace tube is lengthened appropriately for sufficient holding time.
