Problems and Solutions Regarding the Centrifugal Casting of Wire Sheave for Heavy Cranes

Abstract

The centrifugal casting of wire sheave is a technological method that ensures the important quality requirement, the continuity of the material in the active rolling zone of the sheave. However the centrifugal casting has some difficulties: the stability of the casting system, small productivity, gas permeability of the cast mould. The paper shows the problems induced by the centrifugal casting of these parts and the solutions for their solving.
