Pearlitic spheroidal graphite rolls are concentrated characterized by nodular graphite as against flake graphite in the normal cast iron rolls. These rolls are excellent substitutes for many conventional steel and cast iron rolls due to a combination of superior strength. The softest grade has a pearlitic matrix containing ferrite around the graphite nodules, while the higher hardness grades have a complete pearlitic matrix. The carbide content increases pro--portionally with the hardness. accicular spheroidal graphite rolls also have a thick layer of chill. here the name of such rolls is based on the fact that the material consist of nodular graphite and carbides in under cooled austenitic pearlitic -bainitic matrix. the carbide content is considerably higher in the harder grades than the softer ones.

Indefinite chilled rolls are cast iron based rolls alloyed with nickel, chromium and molybdenum having a matrix of pearlite and carbide with flake graphite. These rolls are used primarily for section rolling.the matrix structure varies from fine pearlite to bainite depending on the alloy content. The desired hardness is obtained by changing the carbide/graphite. The material has very good thermal properties used in finishing stands of rod mill.the rolls are to ensure minimum sacrifice of clear chill while achieving maximum functional depth.

Diameter : Upto 32 inches or 850 mm

We are offering alloyed rolls for tmt plants. Alloyed rolls are special steels alloyed with nickel, chromium & molybdenum. Which is used in breakdown, roughing & intermediate mills for finishing of heavy sections. These rolls are statically cast and undergo a three stage high temperature heat treatment comprising of annealing, normalizing & tempering rotation. The rolls 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 rolls for sheet, plate and strip mills. Intermediate and finishing rolls for small section, bar and wire rod mills. Also used as cold mill rolls for ferrous and non-ferrous sheets.

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 forge 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.

Diameter : Upto 24 inches or 610 mm

Length : Upto 48 inches or 1220 mm

d.p.i.c. rolls are made of a high alloy iron and a soft grey iron or ductile iron core metal. having minimal drop in hardness with a good it is recommended to keep the core as nodular iron (sg iron). better roll cooling is required for these rolls in the mill.these rolls are used in finishing stands of rod mills and for flat rolling. the shell material consisting of predominantly bainitic or martensitic matrix with free carbides with small quantities of tiny flake graphite, have excellent wear resistance coupled with resistance to fire cracking.

Diameter : Upto 32 inches or 850 mm

Chilled to graphite being smoother, the hardness associated with the definite chilled structure allows deeper grooving. definite chilled rolls 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 our chilled rolls.Definite chilled rolls have proved well suited for the finishing stand of rod & section mills, for continuous hot strip mills. these make excellent work rolls for two, three and four mills, turning out of high grade ferrous and non-ferrous sheet and strip or section.

Diameter : Upto 32 inches or 850 mm

We offer Chilled Rolls . 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

We offer Chilled Iron Rams. Chilled Iron Rams (Pistons) are chilled casted to get 100% Scratch Proof surface for longer life of Hydraulic Seals. The surface of the Rams is hard enough to withstand almost any climate and yet smooth on seals for long life. Chilled Rams are free from all defects like sand fusion, blow holes, piping & cracks etc. We are manufactured Chilled Rams are having protected centres & having up to 0.01 micron finish These Rams are capable to bear external specific pressures. The hard and grinding mirror polished surface maintains the high hydraulic oil pressure together with the circumstantial seals.

The hard and grinding mirror polished surface maintains the high hydraulic oil pressure together with the circumstantial seals. Chilled Iron Rams (Pistons)take the pressure of the hydraulic fluid on one side and pass them on to the forming tools on the other side for these applications; Chilled Cast Iron or Chilled Spheroidal Cast Iron have proven their reliability for decades. These Hydraulic RAMPiston are made one piece, flange fitted or fabricated along with drilling operation

These rolls are self-possessed mainly of pearlite with some cementite in the structure. adamite rolls are strolled than cast iron rolls and harder than other steel rolls. an outstanding feature of adamite rolls in that the inner hardness is about the same as that of the surface. adamite steel rolls are classified as ordinary. these rolls are used in pre-finishing to polishing stands in structure mills where wear resistance is very important along with considerable amount of strength and toughness.
