Infinite chilled cast iron roll
Centrifugal composite infinite chilled cast iron roll:the outer layer has rather high metallurgical character;almost without changing for graphite quantity in depth location that from the surface to the heart that almost the same hardness;the iron rolls hardness is mainly determined by the basis structure,as austenite,bainite or martensite.
