Definite chilled iron rolls have a high-hardness layer of white cast iron at the surface.There is no free graphite basically in the matrix of work layer of alloy chilled cast iron roll, so its hardness is high with fine wear-resistant property. It can be used in small bar and wirmore...
The working surface of Double Poured Chilled Rolls . shows the white graphite free structure consisting of eutectic carbide and transformed austentite. This gives a hard layer which confers good resistance to wear. The core and necks exhibit a tough grey structure, and the iron omore...
Indefinite Roll is cast using such proportions of silicon, chromium, nickel and molybdenum that the working face is no longer completely white but contains a small amount of very finely divided graphite flakes gradually increasing from face to core with corresponding decrease in more...
