Alloy steel formed by adding some alloy elements into the common carbon steel, through heat-treatment process, the good performance of wear-resistance and toughness can be achieved. It is widely used for backup/roughing roll for plate/strip mill and backup
roll for leveling mill, Roughing roll for plate/section/bar & wire-rod mill; Break-down roll for rail beam/universal section mill; Descaling/roughing/backup/vertical roll for strip mill.
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. Applications Rolling mills TMT type rolling mills
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. Metal pallet, wooden pallet box.

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.
