Abstract

The purpose of this study was to predict the morphologies of the solidification process for pure copper using vacuum continuous casting (VCC) and to verify its accuracy by comparing these findings with observed experimental results. A finite differential method and a cellular automaton (CA) model were used to simulate the macro-temperature field for nucleation and grain growth of pure copper using real data from actual casting operations. From the observed experimental results, the drawing speed of the VCC process was considered as the fundamental parameter. With the increase of drawing speed, morphologies of the copper changed and the position of the liquid–solid zone moved closer to the orifice of the mould. The solidification morphologies simulated with the CA model were in good agreement with the results from the actual casting experiment.
