Abstract

In the low pressure casting of a metal in a mould supplied from below by an electromagnetic pump, the durations of the various stages of the moulding cycle are determined in dependence on the temperature of the mould, the temperature of the metal in the mould and the temperature of the metal in the furnace to obtain optimum casting conditions despite variations in these temperatures.
