Abstract

1,206,045. Electric arc melting with consumable electrodes. ALLEGHENY LUDLUM STEEL CORP. 14 Feb., 1968 [16 Feb., 1967], No. 7335/68. Heading H5H. Consumable electrode vacuum arc melting utilizing reverse polarity is improved by the injection of an inert gas such as argon after the evacuation of the furnace 10, the gas pressure being maintained between 30 and 2000 microns. The arc melting current is 5000- 15000 amperes. The control system 46 controlling the position of the consumable electrode 30 is that of Specification 1,048,436. Reference has been directed by the Comptroller to Specification 1,111,177.
