Bimetallic castings are widely used in the mining industries as construction material for crushers which have to perform high abrasive resistance at the outer side and excellent machinability at the inner side. To manufacture bimetallic casting goods cconsecutive centrifugal and gravity casting methods are commonly applied. Centrifugal and consecutive casting come up with geometrical constraints at the parting line of both materials. This research dealed with the manufacturing of tapered grinding roll by applying gravity casting method. The possibilities of casting the white cast iron outer ring in the preheated ductile cast iron of the inner ring were investigated............
