Filling Pressure Control and Simulation of Electromagnetic Pump for Low Pressure Casting
The aim is to study the method to determine filling pressure calculation control method for aluminum electromagnetic pump (EMP)low pressure casting . First, the experiments have been studied to show the relation between electric current and export pressure of EMP in the different of magnet current and electrode current and the pressure calculation control model has been established. Second, the low pressure casting process for EMP has been simulated to verify the model. The Study show the electrode current and the export pressure present the strict line variety regulation under the condition that the magnetism induction strength is assured. The filling of electromagnetism pump low pressure casting is steady, and the adding pressure control is precise. The electromagnetism pump low pressure casting is the advanced casting method to produce high quantity aluminum castings.
