EXTRA-LOWCARBON NON-AGING STEEL PRODUCTION METHOD Russian patent published in 1995 - IPC

Abstract RU 2034042 C1

FIELD: metallurgy. SUBSTANCE: method provides smelting of semi-finished product with less than 0.05 % share of carbon, partial deoxidation, constant vacuumization under pressure in chamber of less than 6.7 kPa and constant alloying of steel by aluminum; in molten bath, that is fed in vacuum chamber, concentration of carbon and oxygen is maintained equal to 0.7 - 1.0 from their stoichiometric ratio. EFFECT: method is used in metallurgy.
