METHOD OF PRODUCTION OF HIGH-STRENGTH STEEL STRIP AND DEVICE FOR REALIZATION OF THIS METHOD Russian patent published in 2003 - IPC

Abstract RU 2218427 C2

FIELD: method of production of high-strength steel strips. SUBSTANCE: proposed method includes casting of molten steel in one continuous casting unit with one or more production lines for obtaining slab which is transported through furnace by use of casting heat; slab is subjected to roughing in continuous or semi-continuous process in austenite range in roughing unit and is rolled in austenite range in finish rolling unit; it may be rolled in at least one roughing stand of finish rolling unit in two-phase austenite-ferrite range; after escape from finish rolling unit, strip rolled in austenite or austenite-ferrite range to final thickness is quickly cooled for obtaining required structure. EFFECT: enhanced deformation properties. 5 cl, 3 dwg
