Abstract

As a world-wide roll manufacturer the Åkers Group offers products covering almost all the segments of the rolling industry with a permanent will of quality and continuous improvement. Thanks to close relationships with its customers enabling to acquire a good knowledge of their applications, Åkers has set up experimental approaches for a better understanding of the roll degradation phenomena observed in service. These approaches aim at separating each mechanism involved in the global degradation of rolls to bring out the correlation between roll grade properties and the damage mechanisms. Different physical phenomena as oxidation, thermal fatigue or tribology present in the HSM applications have been investigated. Results obtained at the laboratory scale from solicitations with individual or coupled physical phenomena have been confirmed through rolling trials on a semi-industrial pilot-mill.
