High Nickel Infinitely Chilled Cast Iron Roll IV is a high-performance roll designed to meet the demanding rolling requirements of modern steel mills. Made of high nickel-chromium-molybdenum alloy, it has extremely high hardness and wear resistance and can withstand heavy loads and high-intensity wear environments. Its hardness can reach HRC 70-83, which is 2-3 times that of ordinary cast iron rolls, which can significantly reduce the frequency of roll replacement and maintenance costs. It has thermal crack resistance, which can avoid thermal cracks at high temperatures and extend its service life. It has anti-adhesion properties, which can reduce the adhesion of steel billets to the roll surface, reduce surface roughness, and improve the quality of rolled products. It has good peeling resistance, which can prevent the roller surface from peeling and extend its service life. The high-nickel infinitely chilled cast iron roll IV is a high-performance, high-reliability roll that can significantly increase roll service life, improve rolled product quality, reduce rolling costs, and improve production efficiency. It is an ideal choice for modern steel mills to improve production efficiency and product quality.
