Indefinite Chilled Iron Rolls
Special Cast Steel ndefinite chilled iron rolls are cast highnickel grain rolls with fine deposits of graphite on the surface. The hardness of these rolls can be changed by adjusting the chemical composition or by changing the casting method, making it possible to adapt the roll hardness to particular appliions. Because of the presence of graphite, these rolls have a strong resistance to ...

Cast Iron: Properties, Processing and Appliions
Cast iron is an iron alloy containing 2 wt.% – 4 wt.% carbon, 1 wt.% – 3 wt.% silicon and smaller amounts of minor elements [1]. In comparison, steel has a lower carbon content of up to 2 wt.% and a lower silicon content. Cast iron can also be further optimized by alloying with small quantities of manganese, molybdenum, cerium, nickel, copper, vanadium and titanium before being cast.

CENTRIFUGAL CASTING
The centrifugal casting can be used for metal matrix composite (MMC) melts. For example if stir cast aluminium/graphite melt is poured in the rotating mould, graphite particles will segregate in the inner periphery of the centrifugal casting as graphite density is lower than aluminium. Thus such casting can be employed for bearing appliions5.
