Original Abstract

This paper deals with the simulation of solidification and cooling of a massive casting, with various ways of accelerated cooling using steel chills in order to reduce the heterogeneity of the pouring temperature field and to increase the rate of cooling of the casting. The results of the simulation of the temperature field are compared with experimentally measured temperatures. It seems that numerically controlled cooling enables the optimization of the technology of pouring of massive ductile cast-iron castings with spheroidal graphite. The relationships among four characteristic parameters and the corresponding local solidification times were determined in the series of samples that had been selected from defined positions of the massive casting.

Keywords
