Alloy cast steel roll is manufactured with high quality steel molten by arc furnace, due to the advanced casting and thermal treatment technique, such roll is of very high intensity. Owing to its excellent performances of anti-heat crack, tenacity and wear-resistance, it is appropriate to be used for rough and intermediate shape steel rolling machine , heat rolling strip steel rough rolling machine stand and used as back-up-roll for heat rolling strip steel. Its metallographic structure is made of pearlite or temper sorbite.

Forging is a process in which the casted ingot is heated in the furnace & then material is hammered according to the customers sizes & requirements, thereafter heat treatment is done in normalizing/annealing furnace.
Forged rolls are manufactured from carbon steel, alloys steel & stainless steel, these rolls are available in primarily in forged m.s. rolls , forged en-8 rolls , forged en-9 rolls, forgeden-19 rolls, forged en-24 rolls , forged en-31 rolls , forged en-42 rolls forged class 2 & forged class 3 etcetera,

Our forged rolls are available with groove, bearing sizes, ready to use conditions or in semi-finished or in black forged condition, apart from rolls we offer forged product range of forged spindles, forged rings, forged shafts, forged blanks, forged cranks, forged pinion gears, flanges, forged wheels & other specially ordered products, all forged products are dispatched with essential certification, addition to that we also offer ultrasonically tested forgings for variety of applications.

Definite chilled iron rolls have a high-hardness layer of white cast iron at the surface. These rolls have the advantage of selecting the harder best performing material on the working surface, which is primarily a Cr-Ni-Mo alloyed chill cast iron & a relatively softer material inside.
White chill iron is less soft,strong and incapable of withstanding high dynamic stresses but owing to its greater hardness , has enough strength and better wear resistance against thermal shock occurring at the time of accident in the rolling operation compared to other chilled rolls.
These rolls have high compressive strength.It retains a fair proportion of its strength at elevated temperature, for example, in hot rolling .
Chilled to graphite being smoother, the hardness associated with the definite chilled structure allows deeper grooving.
A very fine surface finish is required , rolls for hoop and skelp mills must be chosen with special attention to strength and hardness so the rolls will match the roughing , intermediate and finishing stands.
The rolls are double poured duplex rolls and are manufactured by the advance centrifugal process.
These make excellent work rolls for two, three and four-high mills, turning out of high grade ferrous and non-ferrous sheet and strip or section.
High Alloy Clear Chill Rolls 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.
These rolls are manufactured for section mills producing rounds, squares, flats, Hexagon, Gate Channel as well as mills producing Tor steel and Tmt bars.

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 casted 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 obtained through controlled chemical composition varies the hardness.
It's used in 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.
