METHOD OF CONSUMED TITANIUM AND ITS ALLOYS ELECTRODES PRODUCTION Russian patent published in 1997 - IPC

FIELD: special electrometallurgy, production of ingots and slabs for pieces produced by deformation and pattern castings produced in vacuum electrical furnaces and furnaces of other type in different branches of industry. SUBSTANCE: aim is production of consumed electrodes out of titanium wastes, for example, as metal scrap, cut-outs, cuttings, etc of much higher density and strength. Proposed method to produce strong and high density electrodes provides for activated treatment of wastes for 90 - 120 minutes, heating of lingot with charge up to temperature of 300 - 350 C and top pouring of laid in lingot wastes with similar by chemical composition base allot, in which surface active substance of 0.001 - 0.005 mass %, for example, boron is introduced. In the case, lingot loading density is in limits of 40 - 70 %. EFFECT: production of high strength and density consumption electrodes of titanium waste. 6 cl, 2 tbl
