Chilled cast iron roll
Properities
Centrifugal composite chilled cast iron roll:as rolls surface is covered by chilled structure,the excellent wear resistance of the roll is guaranteed;the iron roll hardness and basic inner structure will be determinded by the site usage condition.
With centrifugal way,the whole roll working layer can be without graphite.With core using spheroidal graphite cast iron,the resistance is improved both on wear resisitance and fracture resisitance.
