Definite Chilled Rolls

The working surface of Our 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 neck are made upon steel shaft in specialized double poured centrifugally cost chill Rollers barrels.

Compared to grey iron, white Rolls is less soft, strong and incapable of withstanding 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 steel re-rolling mills, semi-automatic or Automatic plants, Wire roll plants, TMT plants, Roughing mill Rollers, Intermediate

Mill Rolls for two, three and four-high mills, turning out of high grade ferrous and non-ferrous sheet and strip or section. High Alloy Rolls 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.
