Annealed wire is made of low carbon steel cold drawn, heating and constant temperature, heat preservation process and become a kind of soft wire products.
Wire is different according to the use, composition is different also, it contains ingredients: iron, cobalt, nickel, copper, carbon, zinc, and other elements.
Hot metal billet rolling into 6.
5 mm thick steel wire rod, and then puts it into into a different diameter of line drawing.
And gradually narrowing the drawing plate aperture, cooling, annealing, plating and other processing technology was made from a variety of different specifications of the wire.
Wire production due to process simple, widely used and development earlier.
Wire or steel wire,
The corresponding enterprises' screen enterprises')
Is a steel wire again cold products, generally selected materials of high quality low carbon steel or stainless steel.
Normally, should pass plate shell, pickling, washing, saponification, drying, drawing, annealing, cooling, pickling, washing, galvanizing line, packing and so on a number of procedures, to produce to make the wire (
The iron ingot (
Black wire has good elasticity and flexibility, can control its degree of hardness and softness in the annealing process, made of high quality iron wire is mainly used in the construction industry as a binding wire and cable tie.
There are mainly 5 # - wire
38 # (
Silk by 0.
Than ordinary black iron wire is more soft, more flexibility and softness, chroma.
Wire and wire production widely used drawing technology and galvanized processing.
In 1976, guangzhou galvanized iron factory in the domestic first application of electrolytic pickling, high-pressure washing, card electric drying technology experiment a success drawing line continuous production.
Make the wire drawing process from intermittent production made continuous production, reduces labor intensity, reduce the metal consumption.
At that time, the domestic wire factory can produce wire rope, wire spokes, umbrella wire, spring steel wire and the bicycle saddle spring steel wire and other products.
In the 1980 s, the use of staples hot plated low carbon steel wire, fan net steel, carbon structural steel and surface of steel wire also appeared.
