MELTING APPARATUS FOR SPRAY MOLDING

摘要

A method for regulating the flow of liquid metal to an atomization zone is provided. The regulation is effected by imparting a high density flux to a stream of liquid metal as it descends toward the atomization zone. The high density flux is applied by a flux concentrator. The flux concentrator is a small sleeve-like element attached by parallel conductors to a larger sleeve-like element which acts as a secondary to primary coil extended through the larger sleeve element. By imparting high density flux to initiate a stream passing through the flux concentrator the cross sectional dimensions of the melt stream and the rate of flow of melt through the concentrator is regulated to values which are appropriate for a spray-form type of action.
