Title: Method for smelting extra-low carbon steel
Inventor: NAGAMURA TOKUHIRO
IPC: C21C7/10
Filed: 1988-09-30
Abstract: PURPOSE:To produce the extra-low carbon steel which is clean by adding Al onto ladle slag to a molten steel to reduce FeO with Al when the decarbonization of the molten steel by a rimmed treatment is ended by RH degassing, then by subjecting the molten steel to a deoxidation treatment by RH degassing. CONSTITUTION:The Al or the Al and CaO are added onto ladle slag to reduce the FeO in the ladle slag with the Al when the decarbonization by the rimmed treatment is ended by the RH degassing at the time of subjecting the molten steel refined in a steel refining furnace to the decarbonization treatment by an RH degassing device to smelt the extra-low carbon steel. The m.p. of the slag increases to about 1450 deg.C, the flowability of the slag is improved and the reduction rate of FeO increases, if the SiO2 in the ladle slag is confined to <10% and the ratio CaO/Al2O3 of the CaO and the Al2O3 is confined to 0.67 to 1.50. The oxygen in the molten steel is removed by the RH degassing during or after this reduction. The clean extra-low carbon steel contg. the Al2O3 inclusion at a lower ratio is obtd. in this way and the trouble due to Al2O3 inclusion is eliminated.
