A forged roll meeting the requirements of the cold rolling industry and a method for production of such a roll

摘要

This invention relates in general to the field of forged rolls and to production of forged rolls. More particularly the present invention relates to forged rolls for use in the cold rolling industry. The present invention relates to a forged roll for use in the cold rolling industry and a method for production of such a roll. Said forged roll, comprises a steel composition and a microstructure that comprises: - tempered martensite with a retained austenite rate less than (<) 5 % per volume; and - an open eutectic carbide network with eutectic carbides of less than (<) 5 % per volume; and wherein the roll exhibits: - a hardness between 780-840HV; and - internal compressive between -300 to -500 MPa in absolute values.
