METHOD OF MOTOR CAR SHEET STEEL PRODUCTION Russian patent published in 1996 - IPC

FIELD: ferrous metallurgy, methods of 08Ю mark nonage steel production. SUBSTANCE: method provides for discharging of unreduced metal form steel smelting aggregate in steel casting ladle, addition in discharge process of slime forming material, that has calcium oxide in amount providing slime alkalinity of 2.5 - 3.5, manganese in amount of 0.5 - 1.5 kg per ton of steel and silicomanganese on the basis of 0.3 - 0.5 kg per ton of steel, averaging blowing through by neutral gas in aggregate of metal finishing and introduction of aluminum rods and manganese-bearing materials. In the case usage of aluminum rods is decreased in proportion to added silicon. EFFECT: method allows to decrease aluminum rods usage in proportion to added silicon in production of motor car steel sheets. 1 tbl
