Rolling Mill Rolls



S.G. Iron Roll

S.G. Iron Roll


Item Code: Roll-SGIron

S.G. Iron or Spheroidal Graphite Iron is considered as one of the most versatile roll material. It is produced by a small propostion of magnesium added to the melt as nickel-magnesium or alternative alloy, or pure magnesium. In S.G. Iron roll, the free carbon takes the shape of spheroids or nodules, thereby eliminating the notch effect to flake graphite and imporving upon the mechanical properties of cast iron.

S.G. Iron rolls find application in Roughing and Intermediate mills for rail and structural mills as well as in finishing mills for wire rod and narrow strip mills.


The Chemical composition of S.G. Iron (Pearlitic) Rolls is as follows:

Hardness SH D C Mn Si Ni Cr Mo
50 – 60 3.00 – 3.30 0.30 – 0.60 1.50 – 2.30 1.50 – 2.00 0.40 – 0.50 0.25 – 0.40
60 – 70 3.10 – 3.50 0.50 – 1.10 1.30 – 1.80 1.50 – 2.50 0.50 – 0.80 0.30 – 0.60


The chemical composition of S.G. Iron (Accicular) Rolls is as follows:

Hardness C Mn Si Ni Cr Mo
SH D
65 – 70 3.10 – 3.50 0.50 – 0.80 1.30 – 2.00 2.00 – 3.50 0.30 – 0.80 0.80 – 1.10
70 – 75 3.10 – 3.50 0.50 – 0.80 1.30 – 2.00 2.50 – 4.50 0.30 – 0.80 0.80 – 1.10



Double Poured Definite Chilled Rolls

Double Poured Definite Chilled Rolls


Item Code: Roll-DefChill

Double layered centrifugally casting system is used to produce clear chill – Graphite free white Iron rolls which are called as Double Poured Definite Chilled Rolls (DPCC). These rolls are mostly fitted with Steel shafts in the barrel.

High Alloy Chilled Rolls find application for finishing mill for rod and light section mill as well as for continuous small and medium hot strip mills. 


The chemical composition of Definite Chilled Rolls (DPCC) rolls is as follows:

Hardness SH D C Mn Si Ni Cr Mo
55 - 60  2.90 – 3.20 0.25 – 0.60 0.20 – 0.90 0.50 – 1.00 0.20 – 0.50 0.25 – 0.30
60 - 70  3.00 – 3.40 0.25 – 0.60 0.20 – 0.90 1.00 – 2.00 0.20 – 0.50 0.25 – 0.35
70 - 75  3.20 – 3.60 0.20 – 0.60 0.20 – 0.80 1.70 – 2.50 0.20 – 0.50 0.25 – 0.45



Alloy Steel Roll Or Adamite Rolls

Alloy Steel Roll Or Adamite Rolls


Item Code: Roll-Alloy

These rolls are statically casted and undergo a special high temperature heat treatment process, which is followed by tempering cycles to give it a microstructure consisting of fine pearlitic matrix with spherodised/ broken carbide.

These rolls are special hyper-eutectoid steel rolls alloyed with Nickel, Chromium & Molybdenum. The extra carbon and special alloys give it extra wear resistance and strength.

These rolls are suitable for rolling medium and heavy sections where resistance is very important along with considerable amount of strength and toughness.

The chemical composition of Alloy Steel rolls or Adamite Rolls is as follows:

Hardness SH D C Mn Si Ni Cr Mo
40 - 45 1.20 – 1.40 0.50 – 0.70 0.30 – 0.60 0.6 – 0.9 0.70 – 0.90 0.20 – 0.30
45 - 50 1.50 – 1.80 0.60 – 0.90 0.30 – 0.60 0.6 – 0.9 0.90 – 1.10 0.25 – 0.35
50 - 55  1.60 – 1.90 0.60 – 0.90 0.30 – 0.60 1.2 – 1.5 1.00 – 1.20 0.35 – 0.50



Forged Roll

Forged Roll


Item Code: Roll-Forge

Forging is a process in which the casted ingot is heated in the furnace & then material is hammered according to the customer’s sizes & requirements. Thereafter, heat treatment is done in normalizing or annealing furnaces. Rolls are Ultrasonically tested to check any structural discontinuity or defects.

Forged Rolls find application for Roughing Mills for bar mills, structure mills as well as in Stainless Steel Mills.

The chemical composition of different steel grades that are commonly used in Forged Rolls is as follows:

Grade C Mn Si S P Cr Ni Mo
EN – 8 0.35 - 0.45 0.60 – 1.00 0.10 - 0.35 0.05 0.05 - - -
EN – 9 0.50 - 0.60 0.50 - 0.80 0.05 - 0.35 0.04 0.04 - - -

Double Poured Indefinite Chilled Rolls

Double Poured Indefinite Chilled Rolls


Item Code: Roll-IndChill

Double layered static casting system is used to produce indefinite chill – Graphite containing white iron rolls which are called as Double Poured Indefinite Chilled Rolls (DPICC). These rolls have superior Biting performance, maximum functional depth and ensure minimum sacrifice of clear chill layer. 

Indefinite Chilled Rolls find application for finishing mill for bar mills, wire rod mills and strip mills. 

The chemical composition of Indefinite Chilled Rolls (DPICC) rolls is as follows:

Hardness SH D C Mn Si Ni Cr Mo
65 - 75  3.00 – 3.50 0.55 – 1.20 0.80 – 1.50 1.45 – 2.50 0.80 – 1.50 0.25 – 0.45
