Effect of Surface Shape and Inclination Angle of Inclined Cooling Plates on Morphology and Size of Primary Carbides in Hypereutectic High Chromium Cast Iron

A hypereutectic high chromium cast iron was prepared by inclined cooling plate method, and the effects of surface shape and inclination angle of inclined cooling plate on morphology and size of primary M7C3 carbides in hypereutectic high chromium cast iron were studied. The results show that the primary M7C3 carbides prepared by the inclined cooling plate with bigger groove radius were more finer and rounder. The difference of morphology and size of primary M7C3 carbides prepared by inclined cooling plate with different surface shapes at bigger inclination angle were more obvious than those of being prepared at smaller inclination angle.
