LARGE-SIZED INGOT MOLD OF CRYSTALLIZER OF VACUUM ELECTRIC-ARC FURNACE Russian patent published in 2003 - IPC

FIELD: metallurgy; plants for conducting vacuum electric-arc melting of high-reactive metals, titanium and its alloys in particular. SUBSTANCE: proposed ingot mold is monolithic in construction possessing stable mechanical and heat-conducting properties over entire volume of article. Resistance of ingot mold is enhanced due to increase of number of heats by 1.4-1.6 times providing for high explosion proofness of vacuum furnace due to avoidance of welded joints whose material has low mechanical and thermal physical properties relative to parent metal. EFFECT: enhanced efficiency and reliability. 1 dwg, 1 ex
