Supplier quality of Chinese black iron wire

Process: hot metal billet rolling into 6.5 mm thick steel wire rod, then put it in the drawing device into a different diameter line, and gradually narrowing the drawing plate aperture, cooling and annealing, plating and other processing technology was made from a variety of different specifications of the wire. It contains ingredients: iron, cobalt, nickel, copper, carbon, zinc, and other elements.
Features:
Black wire has good elasticity and flexibility, and can control its degree of hardness and softness in the process of annealing, is made from high quality iron wire, mainly used in construction as binding wire and cable tie. # 5 - # 38 main wire (wire by 0.17 to 4.5 mm)
Traits: black iron wire is more soft than normal, more flexibility and softness, color is consistent.
USES: mainly used in construction, mining, chemical, welded wire mesh, welding hangers, reprocessing, etc. Annealed wire has become soft, flexibility increases, for building tie wire, binding reinforcement effect is better.
Currently, annealed wire and steel wire production widely used drawing technology and galvanized processing. Galvanized iron factory in 1976, guangzhou in the domestic first used electrolytic pickling, washing of high pressure, electric drying of new technology for drawing line continuous production experiment of wire drawing process from the intermittent production continuity becomes production, reduces labor intensity, reduce the metal consumption. At that time, the domestic wire factory produce steel wire rope, wire spokes, umbrella wire, spring wire, bicycle saddle spring steel wire and other products. In the 1980 s, stitching with hot plated low carbon steel wire, fan nets cover steel wire, carbon steel wire and steel wire of the bed structure, etc. Also appeared.
Packing: packed in black iron wire, as well as the packing of the galvanized wire, points in the plastic outside, plastic outside, and with a thin layer of plastic wire wrapped around a circle, wrapping them in a hemp bag or woven bag again!
