Saraswati Chilled Rolls

Sangrur, Punjab

Compared toSARASWATI CASTINGSwhere the chill-zone is graphite-free clear white, Indefinite Roll is cast using such proportions of silicon, chromium, nickel and molybdenum that the working face is no longer completely white but contains a small amount of very finely divided graphite flakes gradually increasing from face to core with corresponding decrease in the amount of carbide.

The Rollers are to ensure minimum sacrifice ofSARASWATI CASTINGSwhile achieving maximum functional depth.Roll of this type have hardness up to about 70 Shore C can be grooved for use in roughing and finishing stands, for processing sections such as T-bars and U-sections, and for roughing and intermediate Rollers of wire and rod mills.g maximum functional depth.

Alloyed rollers are special steels alloyed with nickel, chromium & molybdenum. which is used in breakdown, roughing & intermediate mills for finishing of heavy sections. these rollers are statically cast and undergo a three stage high temperature heat treatment comprising of annealing, normalizing & tempering rotation. the rollers 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 rollers for sheet, plate and strip mills. intermediate and finishing rollers for small section, bar and wire rod mills. also used as cold mill rollers for ferrous and non-ferrous sheets
