METHOD OF INGOTS PRODUCTION Russian patent published in 2002 - IPC

Abstract RU 2191836 C2

FIELD: special electrometallurgy; applicable in production of ingots of titanium high alloys by vacuum arc remelting of consumable pressed electrodes. SUBSTANCE: after preparation of liquid metal bath on bottom of 150-200 mm high, volume of liquid metal during entire melting process is reduced due to reduction of arc current intensity to 7-10 kA, and arc gap value is reduced to 25-30 mm. EFFECT: higher ingot-to-product yield due to reduced casting defects and liquation of alloying elements. 8 cl, 2 ex
