Abstract
We analyzed the crystallization rate in different zones of casting of two-layer chromium-nickel rolls which were obtained centrifugal method. The results show that the increase of the crystallization rate of the metal working layer promotes to the formation of significant residual stresses in two-layer nickel-chromium iron-cast rolls.
