Raw material: Imported virgin Steel billet

Imported virgin billets are used for the production process. Random samples from each batch of the billet (based on heat number) are collected for checking the chemical composition by using spectrometer. Then tested billets are released for production. Billets are charged to re-heating furnace based on heat numbers. The billets are heated up to a temperature of 1150 ° C, by maintaining furnace temperature up to 1200 ° C. The billet temperatures are controlled using automated feedback control system. The temperature sensors fixed around the furnace inner shell provides periodic measurements to the system to maintain the parameters.

Rolling Process

The heated billets are rolled through 18 stands setup in a horizontal-vertical arrangement. We have the capability to produces sizes ranging from 8mm to 40mm. The rolling configuration differs according to the rolling size. Rib formation and logo formation is done in the final rolling stand. Multi slitting technology is used to produce high quality steel bars and also this helps in energy saving through reduced line speeds. Further the rolled material is passed through the quenching box to achieve yield strength in the range of 500-620Mpa. Post this cooling process the material is cut up to 54m lengths and is sent to the “cooling bed”, for self cooling and self tempering process.

Finishing Process

The final cut length as per the customer requirement being cut using the “cold shear” (cut length 5m-12.5m). Further using automated counting & bundling machines the finished goods are bundled and sent to dispatch area using magnetic overhead cranes.
