Steel wire is one of four kinds of steel plates, steel pipes, steel wires and steel wires. According to the cross-sectional shape classification, there are mainly circles, squares, currently, triangles, ellipses, flat, trapezoidal, Z-shaped, etc., according to the size classification, there are ultra-fine <0.1 mm, 0.1 ~ 0.5 mm, thin 0.5 ~ 1.5 mm, medium 1.5 ~ 3.0 mm, thickness 3.0 ~ 6.0 mm, thickness 6.0 ~ 8.0 mm, ultra> 8.0 mm; according to the strength classification, there are low strength <390 mpa, low strength 390 ~ 785 mpa, normal strength 785 ~ 1225 mpa, high strength 1225 ~1960 mpa, high strength 1960~3135 mpa, super high strength >3135 mpa. Utilization: Ordinary quality lines include electrodes, nails, wire mesh, packaging and printing industries and steel and cold-head forging steel cooling rivets, screws, etc., electrical steel, including the production of overhead communication lines, steel core aluminum stranded wires, and special Steel wire, textile thread includes coarse cloth and comb. In 013, needle wire, steel wire rope and spokes produced by steel wire, spring steel wire spring and spring washer and other harp and tire cord, conveyor belt steel wire, steel structure refers to the watch industry, Ball, automatic machine free-cutting steel wire, stainless steel wire, stainless steel wire, including the above purpose and surgical implant wire, resistance wire heater element, resistance element, wire including steel wire and shoe wire tool.
The main process of steel wire production includes raw material selection, iron oxide removal, drying, coating treatment, heat treatment, wire drawing, coating treatment, etc.
The raw material of the fastener is steel wire.
The purpose of removing iron scale is to prevent iron scale from damaging the surface of the mold and steel wire during the drawing process, prepare good surface conditions for subsequent coating or coating treatment, reduce friction during the drawing process, and reduce the drawing force . There are two methods to remove iron scale: chemical method and mechanical method. See chemical derusting and mechanical derusting of wire.
