Description
Steel Wire Rod is a rolled product of round cross-section manufactured by hot rolling and supplied in coils. It is a semi-finished product for further processing and is widely used in various industries.
Production Technology

The manufacturing process includes the following stages:
1.    Billet Preparation: Steel billet (bloom) is heated in continuous furnaces.
2.    Hot Rolling: The billet is sequentially rolled through stands of a rolling mill.
3.    Groove Forming: Gradual reduction of diameter to the required size.
4.    Cooling: Controlled cooling on special cooling conveyors.
5.    Coiling: Automatic coiling of finished product into coils.
6.    Packaging: Strapping of coils for transportation and storage.

Characteristics and Assortment
•    Diameters: 5.0; 5.5; 6.0; 6.3; 7.0; 8.0; 9.0; 10.0 mm.
•    Rolling Accuracy: increased (B) and ordinary (V).
•    Curvature: not more than 2 mm per 1 meter of length.
•    Coil Mass: 800-1500 kg (up to 2000 kg by agreement).
