Buy wire rod at a low price
One special kind of rolled metal is the wire rod, which can be found at the base of wire, ropes, telegraph wires, RC structures. All manufactured products are manufactured in the factory. Accurate observance of norms is a fundamental factor affecting the unchanged quality. When making wire rod, you cannot do without the basic material (carbon steel), on which strength, durability, flexibility depends. The wire rod is also created on the basis of colored products (in this case the cross-section cannot be more than 1 mm). It is interesting that the term "wire rod" was used as the initial word from "rolling".
The essence of production and subsequent application
Reinforcement products, welding wire and nails are made from this strong wire, called wire rod in our days.Usually, a round incision occurs, but one can also find an oval, diameter no more than 10 mm. After passing the production process, the wire rod is used as a separate metal product. Despite the fact that the product is a workpiece, it is presented with rather serious requirements (deviations towards the quantitative content of the elements are possible).The accuracy of rolling, mass, diameter, boundary deviations are strictly verified with Government Standard. The technology of wire rod production begins with processing at rolling special stations. The metal heats up and stretches, passing through the shafts. Due to the fact that the workpiece is crimped from all sides, the corresponding size and shape of the wire are obtained. On the winding equipment, the product is packed in rings. Cooling of the metal product takes place according to one of the developed schemes:
- Natural is carried out slowly, but allows you to create a soft and ductile wire;
- Accelerated passes in two stages by cooling with water or fans, and the result is a solid workpiece
In terms of accuracy, the wire rod is divided into two types: B (conventional) and B (increased accuracy). The curvature of the bars should not be more than 0.2% of the total length. The length is regulated by three types: multiple, dimensional and non-dimensional. Quality wire rod made of alloyed steel sheets has a range of length in the limit: 2 ... 6 m. In the cold state, the product withstands bending up to 180 degrees. The long life of the wire rod is ensured by galvanizing, for which various suitable methods are used - hot dip galvanizing creates the most durable wire.
