Food Processing Mixing Calendaring Cracking Rubber, Calendar & Mixing rolls require high tensile strength along with wear resistance. As such clear chill roll with hardness between 60 - 70 Shore°C is so cast with three different zones of white iron on the surface, mottled iron in the middle and soft gray iron at the core, to ensure good thermal conductivity. All rolls are hydraulically tested to ensure the soundness of the casting.

Double Poured Iron Rolls The inherent advantage of the steel and chill rolls respectively made way for something in between where one can get higher hardness and toughness with better roll-strength. Thus, here, the conventional composite rolls are produced by a special double-pour casting method in which two independent zones - a shell of highly alloyed iron & another a softer graphitic-grey iron core are achieved. The hardest type of roll is one in which cementite is contained in a martensitic matrix. In newly installed up-to-date mills, high speed and heavy reduction rolling is perfo

ICCI Chill Iron Rolls Compared to Clear Chill Roll 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 rolls are to ensure minimum sacrifice of clear chill while achieving maximum functional depth. The transition from Chill to graphite being more smooth, the gradual change in hardness as

Double Poured Indefinite Chill Rolls The working surface of Clear Chill Rolls shows the white graphite free structure consisting of eutectic carbide and transformed austentite. This gives a hard layer which confers good resistance to wear. The core and neck are made upon steel shaft in specialized double poured centrifugally cost chill rolls barrels. Compared to grey iron, white chill iron is less soft, strong and incapable of withstanding high dynamic stresses, but owing to its greater hardness, has better wear-resistance, and has high compressive strength. It retains a fair proporti

Rolls for Non-Metal Applications Milling Cracking & Flaking Mixing Gauging Clear chill in various alloy categories are manufactured for processing of items such as Flour, Cereal, Sugar, Salt, Cattle-Feed, Edible-Oil, Chocolate, Cocoa etc. These rolls in hardness between 450-600 HV (60 -75 Shore°C) have uniform chill & hardness with chill depth between 12-15 mm in most applications (Higher chill for specific application are also offered). These rolls are supplied with either Single through shaft, Stub shaft, or Flange Fitted gudgeons. All rolls are hydraulically pressure tested a
