Wire Rods

Process of Wire Rod Operation

Conditioning of Billets: Wire rod billets are mainly made of continuous casting billet, and their cross-section is generally 150X150 mm². The process followed to inspect the quality of continuously cast billet surface is through visual inspection after removing the scales through shot blasting process. Billet corner grinding as well as the surface grinding facility is available and used for all critical applications before rolling.

Heating: It is generally heated by a walking beam furnace. The walking beam furnace is used to efficiently heat the input material to rolling temperatures with satisfactory temperature uniformity throughout the length and breadth of the as-cast billet for further processing.  As per the typical process requirement, it is to be ensured that the decarburization level is small, the billet is not twisted, and no overheating is caused.

Rolling: The temperature, draft and speed of deformation are the key parameters with which the product is rolled and controlled to meet customer requirements. Further measures to ensure the surface quality include the adjustment of roll roughness and gap, detection of any cracks and dimensional correction.

Post rolling treatment/Stelmor cooling: To attain desired microstructure and mechanical properties after rolling, the rolled product is placed on a conveyor through laying head pipe for Stelmor cooling.
