Double Poured Chilled Rolls: 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
of the transition zone is mottled.Compared to grey iron, white chill
iron is less soft, strong and incapable of with standing high dynamic
stresses, but owing to its greater hardness, has better
wear-resistance, and has high compressive strength. It retains a fair
proportion of its strength at elevated temperature, for example, in hot
rolling. These make excellent work Rollers for two, three and four-high
mills, turning out of high grade ferrous and non-ferrous sheet and
strip or section. High Alloy Clear Chilled Rollers have proved well
suited for the finishing stand of rod and light section mills, for
continuous small and medium hot strip mills, and for strip mills of
older design.
