Abstract
The influence of shrinkage caused by austenitic transformation on thermal fatigue of mill rolls made of four different cast steels was investigated. The samples were collected from the work surface perpendicularly (or close to it) to the axis of the rolls. The dimensional changes (shrinkage) associated with the austenitic transformation were determined by dilatometric examinations. A number of parameters that describe the susceptibility to thermal fatigue of investigated rolls was determined, including the greatest observed crack depth G(max), average crack depth G, average crack path length L, average distance between cracks and others. It was found that the shrinkage associated with the formation of austenite appears to be a main factor contributing to the nucleation and growth of thermal fatigue cracks in cast steel rolls.
