Abstract
631,397. Melting brass chips &c. TRIGGS, W. W. (Chase Brass & Copper Co., Inc.). Feb. 24, 1947, No. 5343. [Class 51 (ii)] A process for melting brass chips, such as those produced by machining operations, or small brass articles such as cartridge cases, comprises maintaining a pool of molten brass at a temperature at which zinc vapours are given off, continuously advancing and agitating the chips with such iron particles as may be included therewith through an air-excluding duct, maintaining an incoming portion of the stream of chips at a temperature sufficiently low to condense zinc vapours thereon while preheating another portion in advance of the cooler incoming portion to a temperature above 1000‹ F., continuously passing a reducing gas through the chips to deoxidise them, and introducing the heated and deoxidised chips through a non-oxidising atmosphere into the pool of melted brass. The chips are preferably preheated to within 100‹ F. of their melting point. In the apparatus shown, the chips are fed through a rotary screw conveyer 11 surrounded by heater elements 16 and fall through 'a duct 18 into a pool of molten brass contained in an induction furnace 20, a reducing gas being introduced under pressure through a pipe 27.
