In order to eliminate hot cracks in the high manganese steel eccentric sleeves during centrifugal casting

a temperature-adjustment mould was used to prepare eccentric sleeves with absence of cracks.The results reveal that the radial tensile stress in inter-layer resulted from different solidification sequence in the middle of eccentric sleeves can be decreased through increasing solidification speed of outerlayer and promoting the sequential solidification from outer to inner layer.And the temperature-adjustment mould can reduce the tangential tensile stress by thermal insulation for thin wall and cooling for thick wall to decrease the solidification speed difference of different wall-thick zone.Both of the two ways can decrease the tendency of the hot crack for eccentric sleeves.
