Rolls Division

We are the supreme Rolls manufacturing company in India as well as international markets, forging our way to the top since 1992. We are proud of our strategic achievements as a leading player across the globe.

1. FORGING ROLLS:8, EN-9, EN-42 & more…
2. CASTING ROLLS:We are manufacturing following types of Rolls

These Rolls are alloyed with Nickel, Chromium, Manganese and Molybdenum with a Carbon content between 0.50% and 2.00% as well as little amount of Vanadium is also added for the improvement of better microstructure. So these are capable of superior mechanical strength with thermal and wear resistance. These Rolls undergo a sophisticated multi-stage high-temperature Heat- Treatment (Double Annealing followed by tempering cycle) to give the combination of hardness, toughness and wear resistance required for the particular application. The lower Carbon grades have a structure consisting of ferrite and fine Pearlite which, as the Carbon content is raised, transitions to a fully Pearlitic structure and on to one containing free carbide in a matrix of fine Pearlite and even some Bainite for the highest Carbon grades. All rolls of this material are statically tangentially single poured.

These Rolls are essentially an Indefinite Chill type material, but with the Graphite in Nodular form instead of flake and having alloyed with higher % of Nickel & Molybdenum along with Carbon. So these rolls have a much higher Mechanical Strength and allow the use of an iron Rolls in applications which would re-present too high a duty for a flake iron quality due to internal ‘notch effect’ of nodular graphite is relatively small. These rolls are very much suitable for the rolling of row products with a wide range of applications due to its hardness penetration, good wear resistance and tough necks, this material has become a benchmark.

These Rolls are stronger and more wear assistance with respect to S.G.I. Pearlitic Rolls and are capable of much higher hardness because of S.G.I. Bainitic Accicular is more alloyed with very higher % of Nickel and Molybdenum than the S.G.I Pearlitic and as a result, the substantial roll material has a bainitic matrix with increased carbide. The name of this material is based on its constituents of nodular graphite and carbides in a bainitic matrix, also called Lower Bainitic. These Rolls become a benchmark in the rolling of long product and is suitable for a wide range of applications due to its hardness penetration, good wear assistance and tough necks. All rolls of this material are statically tangentially single poured.

Alloys Indefinite Chill Iron Rolls have a structure consisting of more flake graphite with few carbides in a Pearlitic matrix. Harder grades have a Bainitic-Martensitic matrix with an increased amount of carbides. The presence of flake graphite improves spalling resistance and also enhances resistance to fire-cracking. All of these properties combined with the excellent surface finish make AIC Alloy Indefinite Chill very suitable for rolling flats sections and similar products where surface finish is critical. Due to alloy additions, hardness penetration is better than that of a clear chill roll and this material may be used in applications with deeper groves such as small and medium section rolling and also for finishing billets. All rolls of this material are statically Tangentially single poured.
