1 Products availableOur Complete range of products are roughing stand rolls, finishing stand rolls, definite rolls and BUNDLE MACHINE.
We manufacture roughing mill rolls from diameter 300 mm to 600 mm and length from 600mm to 1200mm. The hardness of these rolls ranging from 45 degrees to 55 degrees shore C.
FINISHING STAND ROLLSThese rolls are manufactured in the sizes of 250mm to 360mm in diameter and length from 500mm to 600mm. The hardness of these rolls ranging from 70 degrees to 75 degrees shore C.
The working surface ofSARASWATI CASTINGSshows 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, whiteSARASWATI CASTINGSis 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 DEFINITE CHILLED ROLLERS

flour mills by centrifugal spin casting technique, using controlled rotational speed & precise double pouring to produce these rolls, this is the most contemporary and sophisticated method to produce high quality duplex rolls, the cementite & paralytic structure ensures that the rolls have consistent hardness over the entire surface (18-20 mm chilled depth) these rolls are available in sand blasted, smooth & fluted surface finish along with grinding and grooving, completed with shrunk fit forged en-8 & en-9 journals and bearing size operations according to milling bodies of overseas & Indian flour mill manufactures, however semi-finish rolls are also available for further harmonizing of journals

Alloyed rollers are special steels alloyed with nickel, chromium & molybdenum. which is used in breakdown, roughing & intermediate mills for finishing of heavy sections. these rollers are statically cast and undergo a three stage high temperature heat treatment comprising of annealing, normalizing & tempering rotation. the rollers are available in a wide variety of composition & properties to suit specific application.
The matrix structure is pearlitic or bainitic depending on the alloy content. changing the carbide distribution obatined through control of chemical composition varies the hardness. finishing rollers for sheet, plate and strip mills. intermediate and finishing rollers for small section, bar and wire rod mills. also used as cold mill rollers for ferrous and non-ferrous sheets

| Bearing Chocks for the steel re-rolling mills, roller flour mills and other various milling industries, bearing chock is the one of the most important part of modern rolling mills and they have the main influence on the tools of every rolling mill, bearing chocks are installed in between window of rolling mill stands these chocks directly keep the rolls in place, The middle axis of every chock is the base of the overall geometry, all relevant surfaces have to be adjusted to this axis, bearing chocks are ideal for anti friction roller bearings.
