Alloy Indefinite Chill rolls consist of cast iron with fine interdendritic graphite evenly dispersed throughout the barrel of the roll. The size, shape and distribution of the graphite together with Carbide content is controlled by the chilling effect and the alloy content. The additional of alloys such as manganese, nickel, chromium and molybdenum changes the matrix structure from pearlitic, bainite, to martensitic. Presence of these alloys produces rolls with restricted hardness drop along the cross sections.

Application : It can be used in both roughing and finishing stands for bar and and sections, and for roughing, intermediate and finished stands of wire rod mills.
