Equipped with one of the best indefinite chilled cast iron rolls brands, Makkah Export is one of competitive aic mill rolls manufacturers and suppliers in India, Indefinite Chilled Cast Iron Rolls is a cast iron with fine intercrystalline graphite evenly distributed throughout the working layer of roll barrel. The sizes, shapes and distributions of graphite and carbide are controlled by the chilling effect and the contents of alloy elements.
The addition elements such as Manganese, Nickel, Chromium, and Molybdenum changes the matrix microstructure from pearlite,bainite to martensite.The present of small amount of fine graphite enhances the roll’s resistance to spallling, thermal crack and wearability. This roll has small hardness gradient in the working layer of roll barrel and is suitable to medium and finishing stands for TMT Bar, Re-Bar, Square , Flate etc.
We also produce Solid Chill Rolls (DPIC) by sand casting technology. The hardness of these Rolls varies from 55-80-shore hardness at every stage of manufacturing our technical staff endeavors their best to maintain quality.
