Proposed Design of Centrifugal Casting Machine For Manufacturing Of Turbine Bearing

Abstract

Centrifugal Casting, sometimes called roto-casting is a metal casting process that uses centrifugal force to form cylindrical parts. This paper concerns to the proposed design of centrifugal casting machine. To produce turbine bearing. The dimension of the bearing to be produced as follows: Length=700mm, Diameter=1200mm. A bearing used in steam turbine should have good mechanical properties like strength, stress, wear, rigidity etc. A centrifugal casting is the only process by which such type of heavy axisymmetric job can be produced. Due to Centrifugal force (the main aspect of centrifugal casting process), the product homogeneity can be achieved in terms of mechanical properties than other casting processes. For this, a special purpose horizontal axis centrifugal casting machine will be developed. In this paper, the proposed design and function of the components have been covered.
