Patent Images
1. A nozzle for a magnetohydrodynamic atomization systems comprising:
- a housing;
a molten metal feed passage having a first end connectable to a tundish for containing molten metal and a second end; and
electrode means, disposed at least partially in the feed passage at the second end, for passing a D.C. electric current through the molten metal while the molten metal is simultaneously subjected to a magnetic field oriented at an angle perpendicular to the electric current.

Abstract
A spray nozzle for a magnetohydrodynamic atomization apparatus has a feed passage for molten metal and a pair of spray electrodes mounted in the feed passage. The electrodes, diverging surfaces which define a nozzle throat and diverge at an acute angle from the throat. Current passes through molten metal when fed through the throat which creates the Lorentz force necessary to provide atomization of the molten metal.

11. A magnetohydrodynamic atomization system comprising:
-
a tundish for containing a quantity of molten metal; a nozzle including a housing, a molten metal feed passage having a first open end and a second open end and electrode means disposed at least partially in the feed passage at the second end, for passing a D.C. electric current through the molten metal; means for subjecting the molten metal to a magnetic field oriented at an angle perpendicular to the electric current; and conduit means for communicating molten metal from the tundish to the first end of the feed passage. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
