Mandi Gobindgarh · Since 1995
Forged, chill, adamite and SGI rolls for rolling mills, made in-house from the first melt to the final inspection.
A spirit of trust
C.S. Forgings came into being in early 1995, grown out of its mother concern, M/s Prince Steel Industries, on the national highway between Amritsar and Delhi. As India's re-rolling industry expanded and modernised, one unit could no longer meet the demand for rolls, so our founder built a dedicated forging plant.
Today we are one of the most modern roll making organisations, with a precision machine shop and in-house testing, supplying rolling mills across India and abroad.
The rolls
Roughing, intermediate or finishing. Section, wire rod or strip. Choose a family and turn it over.
Drag to turn
Forged
Carbon, alloy and stainless steel rolls, hammered to shape and heat treated. Up to 30″ diameter and 10 MT finished weight.
Solid Chill
Clear (definite) chill cast iron rolls with a hard, graphite-free working surface. Excellent work rolls for 2-Hi, 3-Hi and 4-Hi mills.
Solid Chill
High-nickel cast rolls with fine graphite at the surface. Strong resistance to thermal shock, and a gradual fall in hardness that allows deeper grooving.
Chilled Barrel
Centrifugally cast chilled barrels fitted with EN-8 steel shafts and M.S. rings, for special quality sections and for paper and board mills.
Chilled Barrel
Shaft-fitted double poured chilled barrel rolls: a high-alloy shell over a soft graphitic core, for high-speed, heavy-reduction mills.
Adamite
Specially alloyed with nickel, chromium or molybdenum. Double annealed and tempered for wear resistance and strength in roughing stands.
SGI
Spheroidal graphite (ductile) iron rolls. Graphite nodules remove the notch effect of flake graphite, for small sections and flat rolling.
SGI
SGI alloyed with nickel and molybdenum to form an acicular structure as cast. For heavier sections that need added strength and depth of hardness.
Forged
Heavy forged steel products to your drawing and your size: cranks, shafts, gears, blocks and pinions.
From melt to mill

01
The charge is melted in our induction furnace and refined. Chemistry is confirmed in the on-site Spectro Lab before metal is teemed from the ladle: static, centrifugal or double pour, depending on the roll.

02
The ingot goes back into the furnace, then under the hammer, and is worked to the shape required. Forging elongates the grain, which gives the steel its cohesiveness and strength.
Up to 30″ diameter · 10 MT finished
03
Normalising and annealing relieve stress and set the structure. Adamite rolls take a double anneal and a tempering cycle, for a pearlitic matrix with spheroidised carbide.

Turning, grooving and bearing sizes on our own lathes, vertical lathes, boring, planing, shaping and drilling machines. Supplied ready to use, semi-finished or rough forged.

05
Rolls are checked at every stage against the stipulated specification and dimensions: chemical lab, spectrometer, hardness tester, ultrasonic testing and bending tests.

Each roll carries the shop colour code for its material, so the right roll reaches the right stand. Then it goes out to mills across India, and to Kenya, Sri Lanka, Nepal and the UAE.

Quality & testing
Rolls are inspected at various stages, so what reaches your mill is what was specified. The lab sits on the shop floor, close to the work.
Export
Our quality has earned us a place in the international market. We export to Kenya, Sri Lanka, Nepal, the UAE and beyond, and we are an export award winner.
Environmental management
Gases from melting and refining pass through emission control systems with wet scrubbers and filter bags, and contaminated water is treated and re-used. We keep pollution at the lowest level we possibly can.
