INDEFINITE CHILLED ROLLERS

Compared to SARASWATI CASTINGS where 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 of SARASWATI CASTINGS while achievinCompared to SARASWATI CASTINGS where 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 of SARASWATI CASTINGS while 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.
