Wire Rod Coil

Wire rod coils are a semi-finished steel product that is used to make finished products like wire ropes, barbed wires, aluminum steel reinforcements, and vehicle parts. Hot rod coils are made from hot rolling billets on rolling mills. Vizag steel wire rod coil diameter ranges from 5.5mm to 14mm.

The range of applications of Vizag wire rod coils

Wire rod coils have both commercial and industrial usage like – fencing bushes and agriculture wires, cycle spokes, umbrella ribs, wires, chain rivet, and stapler pin wires. Also, Vizag steel wire rod coils have an extensive application in the production of automobile parts such as engine shaft, fasteners, screws, socket, bush, spline, gear, and connecting rod.

The wide applications of wire rod coils can be understood by the carbon content of the wire rod, for example – a drawn welding rod is produced with medium or high carbon content wire rod. Vizag steel manufactures wire rod coils from completely killed steel through STELMOR controlled-cooling process, which makes it a high-quality product that is second to none. The production capacity of the Vizag steel mill is 0.850 MT per annum of wired rod coils.

Wire rod coils are categorized into –

• Low carbon wire rods
• Medium-low carbon wire rods
• Medium-high carbon wire rods
• High carbon wire rods

Production and quality control

Vizag steel wire rod coils have a uniformed grain size, outstanding finishing, and rigid dimensional tolerance. The STELMOR controlled-cooling process delivers expected metallurgical properties. The weight of a wire rod coil can vary from 600 kg to 2.4 ton, which depends on the mill capacity. Vizag steel ensures that the wire rod is coiled with perfection without any breakage in the bundle. Wire rod coils are also used to protect wire with metal covering, defined as cable armoring. They are also a vital part of making pre-stressed concrete, wire rod coils improve the performance of the concrete in construction.

Steel wire rod coils are cleaned by chemicals and coated with borax, lime, or phosphate afterwards. They are produced according to a purpose, which changes the inspection procedures and shop controls.

A carbon steel wire rod coil has several qualities such as – Industrial quality wire rod, fine wire quality wire rod, cold finishing quality wire rod, chain quality wire rod, wood screw quality wire rod, and many more. Each wire rod coil is manufactured for unique purposes.

Conclusion

The selection of a wire rod coil entirely depends on its purpose. Grading and quality type are the parameters to choose from. Vizag steel wire rod coils don’t break in transport due to sturdy bundling, neither do they get severely corroded due to treatment and coating.
