摘要

Abstract Topic The compound rolling roll whose residual stress is little is offeredru. Solutions Outside the cemented carbide in the compound rolling rollInside fitting inside the ring material, the ring material, outside aforementionedThe cast iron section and the aforementioned cast casting it is welded junction to the inside of the ring materialAnd casting it is the iron part welding and junction, but among the ring materials outside aforementionedFrom the steel section which the surface it fits mechanically, does not have casting welding junctionTo become, at the same time proportion of the aforementioned cast iron section, among the ring materials outside aforementioned15 - 60% it does in the area proportion which is occupied in the whole surface.
