The hot metal billet is rolled into a 6.5mm thick steel bar, that is, wire rod, and then put it into the wire drawing device to draw wires with different diameters, gradually reduce the aperture of the wire drawing disc, and carry out cooling, annealing, plating and other processing processes to make iron wires of different specifications. It contains iron, cobalt, nickel, copper, carbon, zinc and other elements. It is mainly used in construction, mining, chemical industry, welding mesh, welding clothes hanger, reprocessing, etc. After annealing, the iron wire becomes soft and the flexibility increases, which makes the effect of building binding wire and binding reinforcement more effective. Black annealed wire, which is made of low carbon steel or iron, is often applied for weaving, baling in home use and construction. For example, baling hay in agriculture area. Black annealed wire is mainly processed into coil wire, spool wire or big package wire. Or further straightened and cut into cut wire and U type wire. Compared with black iron wire, black annealed wire is more softer and has higher flexibility
