Abstract

The invention relates to a method of producing a grinding roll in which a roll tire made from a highly wear-resistant bainitic cast material is applied to the basic roll body. In order to create a roll tire with particularly high reliability against fractures and with relatively high wear resistance and compression strength, the roll tire is produced from a ductile bainitic spheroidal graphite cast material having a breaking elongation of approximately 0.1 to 2.5% and a compression strength of approximately 1,000 to 1,800 Mpa.
