As a result of our research and studies, we have developed solutions for the problems like sharp hardness falls, minimization of heat cracks due to thermal shocks and keeping the roll life decline at minimum levels in cases where welding is unavoidable.
Our high alloyed ‘Mo’ rolls subjected to a special heat treatment process enable constant hardness from surface to the core of the rolls. This superiority provides strength against heat cracks and breakages.
Nodular graphite cast iron rolls are produced from alloy cast iron spheroidal graphite material that has high resistance to wear.
Softer grades of these rolls are more resistant to heat cracks and harder ones resistant to wear.
