S.g iron rolls are available in a wide range of hardness & composition for a variety of application. These rolls are essentially an indefinite chill type material, but with the graphite in nodularform instead offlake and having alloyed with higher % of nickel & molybdenum along with carbon. The matrix structure varies from ferrito-pearlitic, pearlitic to bainitic & martensitic together with different carbide contents and graphite in the form of spheroidsnodules. Some critical grades are heat treated for higher strength.

ndefinite Roll is cast using such proportions of silicon, chromium, nickel and molybdenum that the working face is no longer completely white but contains a small amount of very finely divided graphite flakes gradually increasing from face to core with corresponding decrease in the amount of carbide. The transition from Chill to graphite being more smooth, the gradual change in hardness associated with the indefinite-chill structure allows deeper grooving.

We manufacture quality range of forged rolls that find application in steel rolling, textile, cement and fertilizer plants. These forged rolls are available in various weights, diameters and thickness to meet varied applications and client’s requirements.

The working surface of double poured chilled 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 necks exhibit a tough grey structure, and the iron of the transition zone is mottled.

Definite chilled iron rolls have a high-hardness layer of white cast iron at the surface.There is no free graphite basically in the matrix of work layer of alloy chilled cast iron roll, so its hardness is high with fine wear-resistant property. It can be used in small bar and wire rod as well as narrow strip steel fine rolling machine stand, and metallographic structure contains fine pearlite and carbide.

These Rolls consist of lower carbon materials with some alloying, especially chromium. This range of rolls are capable of a higher strength and wear resistance and are capable of good surface finish. These Rolls are supplied with a carbon content of up to 1.5% and are heat treated to give a hardness which is normally between 30 and 45 degrees Shore C.

We are offering adamite rolls. These rolls are special hyper-eutectoid steel rolls alloyed with nickel, chromium & molybdenum. The extra carbon and special alloys give extra wear resistance and strength. 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.

We are offering chilled rolls. High alloy clear chilled rollers have proved well suited for the finishing stand of rod and light section mills, for continuous small and medium hot strip mills, and for strip mills of older design.

We are offering cast iron rolls. It can be used in small bar and wire rod as well as narrow strip steel fine rolling machine stand, and metallographic structure contains fine pearlite and carbide.

These rolls are very much suitable for the rolling of row products with wide range of applications due to its hardness penetration, good wear resistance and tough necks, this material has become a benchmark.

We also supply and export of a wide range of steel rolling mill machinery. These steel rolling machinery are fabricated using premium quality raw material, out of these mill machinery find their applications in various industries. We offer these mill machinery to our valuable clients at competitive market rates.
