Abstract
935,065. Deoxidizing steel. BIRMINGHAM SMALL ARMS CO. Ltd. Dec. 21, 1959 [Sept. 25, 1958], No. 30598/58. Class 72. A method of deoxidizing steel comprises subjecting the molten steel to a low pressure, passing hydrogen through the metal to remove oxygen, and then passing an inert gas, having a partial pressure low with respect to hydrogen, through the metal to remove hydrogen. The inert gas may be argon or nitrogen alone or mixed with a completely inert gas. As shown, a vessel 1 containing the molten steel may be supported within a vacuum chamber 4 and hydrogen passed into the vessel through a pipe 10 connected to a hollow projection 11 on the vessel, the projection may have a heating coil surrounding it. In a modification, Fig. 4 (not shown), the metal may be raised into a vacuum chamber, the hydrogen and inert gas acting as a gas-lift. In this case part of the metal is at atmospheric pressure and part at low pressure.
