Abstract

The alloy powder is made using apparatus comprising, in combination, a fluid-cooled hearth 12 for receiving metallic material which defines an alloy and which is to be melted, a plasma heat source 20 adapted to melt the metallic material, a powder metal producer 46, and means to introduce the molten metallic material from the hearth into the powder metal producer. The fluid-cooled walls of the hearth resolidify a portion of the molten metallic material to form a skull as a barrier between the hearth and additional molten alloy produced within the hearth. This method and apparatus restricts introduction of impurities into the molten alloy which is later introduced into the powder metal producer. In one form, a fluid- cooled pouring trough 34, as a stream control device, can be disposed between the hearth and the powder producer to receive molten metal from the hearth and to introduce it into the powder metal producer. <IMAGE>
