Mfrs. Of: DPIC Chill Rolls, Adamite Rolls, Definite Shafted Rolls, S.G. Iron Rolls, Indefinite Chill Rolls, Forged Rolls. Bearing Chowks for Automatic & Semi Automatic Steel Re-Rolling Mills
Cast steel Rolls are available in wide of chemical compositions varying from Hypo Eutectoid to Hyper Eutectoid steels. Alloying combinations of different element like Cr, Ni & Mo are normally used to achieve the desired physical and mechanical properties.
In view of the demanding end use requirements these rolls can not be used in an as cast condition. When a coarse grain pearlitic structure with cementite and ferrite in a continuous network is normally obtained. The rolls are subject to specially designed heat treatment cycles to arrive at the optimum microstructure configuration with fine pearlite and uniformly distributed suitable for the final application.
