Definitions
- the present invention relates toa method of producing powder and'more" particularly to a'method of producing pre-alloyedmetallic powder.
- the Figure is a schematic view of an embodiment of the apparatus for producing pre-alloyed powder from consumable electrodes.
- FIG. 1 is a schematic view of a particular embodiment of the invention. It comprises reservoir or tundish 10, having an inlet 10 and outlet valve 10'', which holds and homogenizes molten metal 20, supplied from consumable electrodes 11 and 12 (either electrode could have been nonconsumable), electrical connections 13 and 14 for striking an are between electrodes 11 and 12, hydraulic pressure cylinders 15 and 16 for moving electrodes 11 and 12 together.
- a method according to claim 1 wherein said atomizing comprises the step of passing said homogenized molten metal onto a moving disintegrator.
