Rolls made of high speed steel (HSS) have been prepared by centrifugal casting with electromagnetic stirring. During the centrifugal casting process of HSS rolls, segregation of alloy elements occurs due to the centrifugal force either to the outer or to the inner side of the rolls depending on the relative densities of alloyed elements and molten steel. The experimental results show that the electromagnetic stirring lessens the segregation of the alloyed elements in the centrifugally cast HSS roll. Moreover, the segregation of tungsten, molybdenum and vanadium is obviously diminished with increasing magnetic intensity but the segregation of vanadium increases again when the intensity of the electromagnetic field exceeds 0.053T. The reasons for these phenomena are analysed.
