Abstract

27,806. Ramage, A. S. Nov. 29. Ore and oxide processes; annealing; deposited iron, refining.-Spongy iron is obtained by reducing magnetite, or other ore &c., at a dull red heat with water-gas rich in hydrogen. Hydrogen is removed from electrolytically deposited iron, obtained by using the spongy iron as an anode, by melting the iron with an oxide of an alloying metal, such as chromium, vanadium, titanium, or tungsten to form a steel; a mass of spongy iron containing titanium oxide may be used for this purpose. A gas capable of oxidizing the hydrogen may also be used, or the hydrogen may be removed by annealing under reduced pressure. Specification 9991/90, [Class 41, Electrolysis], is referred to.
