Research on Mechanism of Overland Flow Losses of Direct-Current Conduction Electromagnetic Pump for Casting

Abstract:

Compared with other factors, overland flow losses have stronger influence on the efficiency of direct-current conduction electromagnetic pump for casting. Mercury-media simulation of direct-current conduction electromagnetic pump is used. The mechanism of overland flow losses by changing the structure of liquid inlet was studied and got effective method of inhibiting overland flow losses. It can provide theoretical support for improving the efficiency of direct-current conduction electromagnetic pump.
