The working surface of Dynamic Rolls shows the white graphite free structure consisting of eutectic carbide and transformed austentite. This gives a hard layer which confers good resistance to wear. The core and neck are made upon steel shaft in specialized double poured centrifugally cost chill Rollers barrels. Compared to grey iron, white Dynamic Rolls is less soft, strong and incapable of withstanding high dynamic stresses, but owing to its greater hardness, has better wear-resistance, and has high compressive strength. It retains a fair proportion of its strength at elevated temperature, for example, in hot rolling. These make excellent work steel re-rolling mills, semi-automatic or Automatic plants, Wire roll plants, TMT plants, Roughing mill Rollers, Intermediate mill Rollers for two, three and four-high mills, turning out of high grade ferrous and non-ferrous sheet and strip or section. High Alloy Dynamic Rolls have proved well.



These rolls have hard alloy iron on the working layer and soft grey iron or SG iron core depending upon the application. The shell matrix with proper distribution of carbides and graphite imparts high wear resistance, stability in shape and good surface finish. The softer core ensures good mechanical properties and resistance to thermal & mechanical loads.


Adamite Rolls are basically alloy steel rolls (a kind of high carbon steel) having hardness ranging from 40 degrees shore c to 55 degrees shore c with carbon percentage ranging from 1.35% to 2%. These rolls are primarily supplied for initial stands, where wear resistance is important along with considerable strength and toughness, adequate heat treatment is very much necessary to achieve requisite wear resistance along with strength and toughness, the roll contains carbides, and therefore the wear resistance is obviously improved comparing with hypo-eutectoid and eutectoid steel, to obtain excellent comprehensive properties modification is conducted with special rare-earth or other powerful agent, then through a multi-stages heat-treatment process, that consists of briquette carbides dispersed in the matrix of palletized pearlites can be gained, which perform well on strength, toughness and hot crack resistance. Apart from that a vast range of S.G Iron rolls is also available in a range of : 50, 60, 65, 70, 75 and 80 shore D.These admite rolls offer higher durability and life to clients.


Spheroidal Graphite Iron Rolls (S G Iron) is considered as one of the most versatile roll materials nowadays. It is produced by a small proportion of magnesium added to the melt as nickel-magnesium or alternative alloy, or as pure magnesium. In S G Iron Roll, the free carbon takes the shape of spheroids or nodules, thereby eliminating the notch effect of flake graphite and improving upon the mechanical properties of the cast iron. In these rolls the graphite is in the form of spheroids produced by suitable inoculation.Most nodular iron rolls are chill cast resulting with a hard working layer and softer nects. The alloy content is accurately controlled to give fine and well distributed graphite nodules and refined carbide in generally pearlitic or bainitic / martenstic matrix. The Higher alloy content Cr-Ni-Mo makes the rolls more tougher & wear resistant.

Forged Rolls 

Forging where in the material is hammered according to the customers sizes & requirements is a process in which the ingot is heated in the furnace & then forged. the forging process help in cohesiveness and strength by elongation of the grain structure, which results in material having much higher load bearing capacities as compare to casted material. Heat treatment is done in normalizing / annealing furnace and forgings are ultrasonically tested thereafter. We have the capacity to supply a single piece up to 7000 kg. in plain carbon steel such as M. S., Class-2, Class-3, EN-8, EN-9 & EN-42, EN-31, EN-19, EN-24, EN-41b, EN-353, EN-25, EN-18 etc. These forged rolls are basically used for rolling purpose in industries where Girders, Channels, Angles are manufactured.
