ABSTRACT:
The invention relates to an automatic process for regulating a casting cycle which uses a machine exerting a low pressure. It comprises controlling the level of discharge pressure introduced into a furnace in order to raise metal being cast according to precise dynamic and physical conditions. By using an ultrasonic sensor, random non-predetermined phenomena accompanying the casting, such as lowering the level of metal in the crucible and leakage of discharge fluid, are taken into account in regulating the casting cycle and casting or forming metal within a mold.
