ADAMITE Rolls

Steel Rolls 'as-cast' without treatment are not suitable for rolling. Dendritic structure, coarsegrain, non- homogeneity and internal stresses make it poor in mechanical properties. So these rolls are subjected to precisely calculated & controlled heat treatment, thereby distributing wildly scattered Cementite/Ferrite more evenly while retaining the basic Pearlitic structure so important to Alloy Steel Rolls.
Such rolls have higher strength at the cost of hardness decrease compared to chill or SG Iron Rolls, making them suitable for heavier passes and serve stress in the roughing & intermediate.

Alloy Cast Steel Rolls They are chiefly applied for the mills where the strength of biting quality is taken into further consideration than wear resistance. A wide range of Alloy Cast Steel Rolls have been developed to meet individual application, depending on their carbon content and heat treatment.

Alloy Steel Base (Adamite) Rolls Their performance in rolling operation is generally placed in the middle way, lying between the quality of Alloy Cast Steel Rolls and the of SG Iron Rolls.
The rolls are heat treated for many hours under the rigid control of metallurgical standard. Their resistance to wear and abrasion of the rolls is quite excellent.
These rolls are incompareable for rolling Rails, Angles, Channels and Beams where deep passes are necessary. They are specially recommended for high tonnage of Billet, Sheet Bar and Rails and where very long rolling period is required. They are extensively used for heavy duty work, such as blooming and slabbing.
