Overview
Rolls forged, heat-treated and machined in-house
Vikrant Forge Pvt. Ltd. (est. 1985) makes forged and machined rolls at its integrated plant near Kolkata, India. Our rolls include run-out table (ROT) rolls, segment rolls and double barrel rolls for steel plants, and geared roller shafts with pinions. Each roll is forged, heat-treated and finish-machined under one group, from steel melted at our sister mill.

How we make them
From melt to dispatch
- 01
Electric arc furnaceSister mill
Eccentric bottom tapping gives cleaner steel with less slag from the first melt.
- 02
Ladle refining
Chemistry and temperature are controlled before casting.
- 03
Vacuum degassing
The melt is held under 1 Torr vacuum to remove dissolved gases.
- 04
Bottom-poured ingots
An ingot casting car pours with little turbulence for clean steel.
- 05
Forging
Manipulator-handled billets are shaped into open-die forgings.
- 06
Heat treatment
Controlled furnace cycles set the grain structure and mechanical properties.
- 07
Finish machining
CNC machining to the drawing's final dimensions.
- 08
Quality assurance
Inspection at every stage, with CMM and our NABL-accredited lab.
- 09
Dispatch
Packed and shipped to customers in India and abroad.
