Tejasavi Rolls India Focal Point, Patiala, Punjab

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 spheroids/nodules. Some critical grades are heat treated for higher strength. 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.Application: Roughing and intermediate rolls for slabbing and blooming mills. Roughing, intermediate and finishing for structural mils. Finishing for wire rod and narrow strip mils.

Indefinite 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. Thus Indefinite Chill Rollers are superior in biting performance and have enough strength and resistance against thermal shock occuring at the time of accident in the rolling operation compared to Indefinate Chilled RollsApplication : Plate, Medium, Narrow Strip, TMT, Wire Rod, Round & Bar.

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. Compared to grey iron, white chill iron is less soft, strong and incapable of with standing 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 Rollers for two, three and four-high mills, turning out of high grade ferrous and non-ferrous sheet and strip or section. 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.  Application : TMT, Wire Rod, Round & Bar, Plate, Medium and Narrow Strip.  

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.Application : Plate, Medium, Narrow Strip, TMT, Wire Rod, Round & Bar

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.Application : Heavy Section, Medium Section, Light Section, Beams, Rail & Bar Mills, Medium & Narrow Strip TMT & Wire Rod Mills, Heavy, Medium & Light Section Mills.

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.Application : These Rolls are suitable for rolling medium and heavy sections. These rolls are also used for roughing stands of strip mill.
