Alloy Indefinite Chilled Iron Rolls

Alloys Indefinite Chill Iron Rolls have a structure consisting of more flake graphite with few carbides in a Pearlitic matrix. Harder grades have a Bainitic-Martensitic matrix with an increased amount of carbides. The presence of flake graphite improves spalling resistance and also enhances resistance to fire-cracking. All of these properties combined with the excellent surface finish make AIC Alloy Indefinite Chill very suitable for rolling flats sections and similar products where surface finish is critical. Due to alloy additions, hardness penetration is better than that of a clear chill roll and this material may be used in applications with deeper grooves such as small and medium section rolling and also for finishing billets. All rolls of this material are statically Tangentially single poured.
