What is the difference between the composition and production process of iron wire and that of black iron wire?
2022-11-08
wire
1. Alias: low carbon steel wire.
2. Composition: The composition is different according to different uses. It contains iron, cobalt, nickel, copper, carbon, zinc and other elements.
3. Process: hot metal billets are rolled into 6.5mm thick wire rods, and then they are put into the wire drawing device and pulled into lines of different diameters, and the hole diameter of the wire drawing disc is gradually reduced, and various iron wires of different specifications are made by cooling, annealing, coating and other processing processes.
4. Use: There are many kinds of iron wires, which are softer than steel wires. They are mainly used for black silk cloth weaving, burning wire and binding wire in the construction industry.
Black wire
1. Process: hot metal billets are rolled into 6.5mm thick steel bars, that is, wire rods, which are then put into wire drawing devices and drawn into lines of different diameters. The hole diameter of wire drawing dies is gradually reduced, and various iron wires of different specifications are made by cooling, annealing, coating and other processing processes.
2. Composition: Its main components include iron, cobalt, nickel, copper, carbon, zinc, etc., as well as other elements.
3. Characteristics: softer and more flexible than ordinary iron wire, with uniform softness and consistent chroma.
4. Use: mainly used in construction, mining, chemical industry, welding mesh, welding clothes rack, reprocessing, etc. After annealing, the iron wire becomes soft, and the flexibility is increased. The effect of building binding wire and binding reinforcement is better. At present, the production of annealed wire and steel wire generally adopts drawing process and galvanizing treatment
