Abstract
A method of producing ferrotitanium alloy from sponge titanium includes placing sponge titanium in a receptacle and pouring molten iron or steel onto the titanium so that the molten metal flows downwardly and outwardly through the titanium to melt the titanium and mix therewith. While the molten iron or steel is being poured onto the titanium, an inert gas in introduced into the receptacle to prevent oxidation of the titanium. After the molten iron or steel has melted the titanium, the mixture is stirred to eliminate porosity in the resulting alloy.
