Abstract

Abstract

A computer program to simulate the temperature distribution and the volumetric changes occuring in ductile iron rolls during solidification is presented. Direct finite-difference method has been used to calculate the temperature distribution. With the help of computer modelling a new technique for producing riserless ductile iron roll castings has been developed and a perfect sound ductile iron roll castings without riser has been produced.
