Abstract

PURPOSE: To produce the metal powder of low oxygen economically with a simplified device by letting molten metal fall into a high-speed-revolving cooling medium and letting the same disperse and quench.
CONSTITUTION: Molten metal 5 being supplied into a tundish 1 is allowed to fall by gravity through a bottom hole 1a into a tank which is revolving at high speeds. At this time, the atmosphere in the tank is also making high-speed rotating motion, and therefore the molten metal 5 falls along the rotating direction of a cooling medium 7 such as water or the like. It then hits against the cooling medium 7 and disperses on its surface, thence it is absorbed into the cooling medium 7 and is further accelerated by centrifugal forces and is thereby quenched to become metal powder 8. during this time, inert gas is supplied from supply ports 10, 11 to prevent the oxidation of the falling molten metal 5. By this method, the oxygen amount in the low alloy steel powder is decreased. In addition, the impact value of the sintered forging which utilizes this powder is improved.
