An experimental ferrous casting machine of 20 lbs. capacity was designed and constructed to evaluate rheocasting and conventional casting processes. This machine is a bottom-pour furnace in which the transfer of the metal slurry to the mold was accomplished by pressurizing the furnace chamber and retracting a stopper rod. The melting and casting operation took place entirely under an inert atmosphere at low positive pressure to minimize slag formation. Several experimental models of both conduction and induction type MHD valves were made and it has been demonstrated that some lift can be obtained from these MHD devices to hold the bulk metal and to control its flow but a much stronger lift force would be required for any practical casting machine. Protective coatings for graphite were studied.
