For hot rolling wires of high-alloyed steels or superalloys tools are nowadays made of cemented carbides. In service they suffer from roughening of the surfaces and severe wear, which deteriorates the surface quality of the wires and restricts the lifetime of the tool. Due to their high hardness and good high-temperature properties, improvements of tool behaviour can be expected by the use of ceramic. In this paper the suitability of silicon nitride as material for rolls is investigated.
