REBARS


The Process

MISCO produces rebars from billets manufactured in house through Electric Arc Furnace Route Steel Making and Continuous Casting process. Stringent quality control measures ensure that the rebars produced in MISCO have the best quality physical and chemical properties with Zero product defects in order to meet customer satisfaction.

Rebars are manufactured in MISCO as a part of the Continuous Mill Technology. Hot billets are directly charged to the Rolling Mill through an Induction Heater which keeps uniformity of temperature through-out the Billet to have better quality product and a higher yield. Billet is rolled to finished product with state-of-art high speed Rolling Mill with fully automated Process supplied by SMS-Meer with Horizontal & Vertical sequence and through High Speed finishing blocks.

After Rolling through highly automated and sophisticated Rolling Mill, the Bars are Thermo Mechanically Treated at controlled thermo-processing channel with controlled cooling water flow to produce products with high mechanical properties. Finished TMT bars are stored or dispatched as per order.
