ALLOY STEEL BASE (ADAMITE) ROLLS STEEL CASTING

Steel Rolls 'as-cast' without heat treatment are not suitable for rolling. Dendritic structure, coarse grain, non-homogeneity and internal stresses make it poor in mechanical properties. So these rolls are subjected to precisely Comentite/Ferrite more evenly while retaining the basic Pearlitic structure so important to Alloy Steel Rolls.Such rolls have higher strength at cost of hardness decrease compared to Chill or S G iron Rolls, making them suitable for heavier passes and severe stress in the roughing & intermediate stands.Alloy cast Rolls are chiefly applied for the mills where the strength or biting quality is taken into further consideration than wear resistance. A wide range of Alloy cast Steel Rolls have been developed to meet individual applications, depending on their carbon content and heat treatment.Alloy steel Base Roll performance in rolling operation is generally placed in middle way, lying between the quality of Alloy Cast Steel Rolls and that of S G 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 incomparable 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 duty work, such as blooming and slabbing.
