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.

The working surface of Clear Chill 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.

Indefinite chilled rolls are basically controlled under actual casting and molding conditions, does not solidify completely, even surface contains small amounts of very finely divided carbide, the graphite gradually increases simultaneously in size and in amount from surface to core accompanied by decrease in carbide content, the matrix is generally pearlitic throughout the cross section, indefinite chilled rolls are using extent of silicon, chromium, nickel and molybdenum, resulting, that the working face is no longer completely white (this feature make it different from clear chill rolls where the chilled-zone is graphite-free clear and white) the desired hardness is obtained by changing the carbide/graphite balance which is achieved by a close control of chemistry and process parameters

Jai Bharat Castings are manufacture & exporter of chilled rolls for roller 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

Pearlitic Spheroidal Graphite Rolls have a thick layer of cast iron with nodular graphite, the name of such roll is based on the fact that the material consists of nodular graphite and carbides in a pearlitic matrix, the softest grades have a pearlitic matrix containing ferrite around the graphite nodules, while the higher hardness grades have a complete pearlitic matrix, the carbide content increases proportionately with the hardness.

Jai Bharat Castings are front runner in 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.

Jai Bharat Castings has maintained its leadership in designing & manufacturing of chilled cast iron straightening rolls (reels / rings) solution for almost all straightening applications through its clear chill compound casting, profile of the working surface is decisive for the production process of straightening applications high surface profile have sufficient hardening depth due to its advanced centrifugal casting ,beside manufacturing chilled cast iron reels JBC also able to produced high chromium, nodular iron, adamite, spheroidal graphite iron or forged / tempered, straightening rolls / reels for special applications , straightening rolls / reels are available semi-finished , full machined or axel mounted condition

Jai Bharat Castings experts in manufacturing of horizontal centrifugally cast double layer straight bore clear chill - chilled roll barrels for triple roll mills, in this course of casting two independent zones - a shell of highly alloyed iron (working layer) of white iron & another a softer graphitic - (non working layer) of grey iron is achieved during the casting along with desired straight bore & wall thickness, harder chilled layer assure longer life of rolls and soft gray iron layer allows smooth mechanical task of drilling, sizing & shaping etcetera, chilled roll barrels can be supplied plan cast, semi-finished or full machined as hollow barrel along-with grinding & mirror polish

Universal couplings are parts to connect the sets of axis and to transfer movement and angular force of mechanical products. They are widely used for machinery of steel rolling mills, mining, metallurgical rolling, petrochemical, hoist lifting and wind power making turbines etc. They are classified into types of mechanical, hydraulic and electromagnetic. Mechanical type is the most common one. It is classified into rigid type, flexible type and safe type according to different standards & end user application

Rigid type couplings have the main functions of connection and transmission, such as flanged type, sleeve type and clamping type, flexible type couplings have the main functions of connection, transmission, buffering and compensation, such as gear type, membrane type, chain type, universal type and non-metal flexible type.Safe couplings have functions not only as above mentioned, but also overload protection, such as ball type, friction type and pin connected type.

fThe material properties of the Roller Mill Rolls are adapted to the specific demands for grinding, crushing, cracking, flaking or crumbling in flour mills, oil mills, cereal plants, coffee mills, chocolate plants as well as in feed mills.

Chilled Rolls manufactures mill rolls for cereal & grain milling, oil seed crushing, flour & feed milling, rice flaking, biscuit, coffee & chocolate industries by centrifugal spin casting process. The cementite & pearlitic structure ensures that the rolls have consistent hardness over the entire surface. Rolls can be supplied as solid cast or hollow as bodies only or complete with shrunk fit spindles.
