Infinitely Chilled Cast Iron Roll II (ICII) is a cast iron roll designed specifically for small section mills. The rolls are made of high-nickel-chromium alloy, which has extremely high hardness and wear resistance and can withstand high stress and wear during the rolling process. It has good thermal crack resistance to avoid cracks at high temperatures. It has good thermal conductivity and can dissipate heat evenly to prevent local overheating of the roller body. The long service life can reduce the frequency of roll replacement and reduce maintenance costs. The ICII rollers are precision machined and have a high surface finish, ensuring that the rolled metal products have high-quality surface finish and dimensional accuracy. Infinitely Chilled Cast Iron Rollers II (ICII) has a lower manufacturing cost than some more expensive roll materials, but the performance is still able to meet the requirements of small section steel mills, making it cost-effective.
