ABSTRACT:
An annular casing for the press rollers of roller presses for the pressure comminution of particulate material, the outer surface of which casing always has a high degree of hardness and consequently a high wear-resisting capability, but the radially inner region of which casing has a lower degree of hardness to avoid casing ruptures, it is proposed according to the invention that the material of the casing consists of nodular cast iron with at least the alloying elements Ni and Mo and with a bainitic structure with residual austenite, and in that, to achieve a self-hardening surface, the boundary layer of the annular casing—contains martensite, which is constantly renewed by external pressure loading of the casing surface when the press roller is in operation.
