National Iron and Steel Industry Mandi Gobindgarh, Fatehgarh Sahib, Punjab

We are offering sg iron rolls. Our company is well known for offering superior quality sg iron rolls to our valued clients. These iron rolls are manufactured using the best quality stainless steel rolls in sgi. These rolls are fabricated using stainless steel (c.i. Chill, solidbarrels) in compliance with international quality norms to offer flawless range. Our range possesses great strength and ensures high tear resistance even in long run.

Nodular accicular rolls are widely used for hot rolling applications in different type of intermediate, prefinishing and finishing group stands. The material consists of nodular graphite and carbides in martensitic and bainitic matrix. SGAC rolls are more wear resistant than nodular pearlitic rolls. Depending on the primary requirements there are variety of standard and also more alloyed grades used considering rolling mill operational conditions and specially wear resistance which is increasing with hardness drop if compared with standard grades considering the type of groove / caliber.

As the name implies, the barrel surface of these rolls does not show a clear chill layer but rather a gradual transition from a carbide rich structure containing a small amount of fine graphite at the surface to a grey core material. These Rolls ensure minimum sacrifice of clear chill while achieving maximum functional depth. The transition from Chill to graphite being smoother, the gradual change in hardness associated with the indefinite-chill structure allows deeper grooving. Thus Indefinite Chill Rolls are superior in biting performance and have enough strength and resistance against thermal shock occurring at the time of failure in the rolling operation compared to other Chill Rolls. The presence of the graphite improves spall resistance and also enhances resistance to fire cracking. These Rolls are available in Pearlitic matrix as well as Accicular/Bainitic matrix as well depending on the requirement of rolling mill.

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, forged EN-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 applicationsAdvantage : 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 forged rolls offered by us having good combination of the hardness surface with high resistance to wear, heat check and though core resistance to breakage it also has an ideal hardness profile from surface to core and very high resistance to spilling, we offer all it in accurate size, weight & finish with very quick & timely delivery Applications : Forged Rolls for Cold Rolling Mills Large Diameter Forged Shafts Forged Wheels Roughing Stand Forged Rolls Forged Back-Up Rolls Forged Reduction/Pinion Gears Forged Rolls for Stainless Steel Mills Forged Blanks / Cranks All Grade Forged Cylinders Forged Roll for Hot Steel Rolling Mills

These Rolls are special hyper-eutectoid steel rolls alloyed with Nickel, Chromium & Molybdenum. The extra Carbon and special alloys give extra wear resistance and strength. These rolls are statically cast and undergo a special high temperature heat treatment process of double annealing followed by tempering cycles to give a micro structure consisting of fine pearlitic matrix with spherodised / broken carbide.Application : These Rolls are suitable for rolling medium and heavy sections. These rolls are also used for roughing stands of strip mill.
