| titleOfInvention | Method for refining molten steel |
| abstract | The present invention suppresses the slag entrainment of molten steel that occurs during non-steady pressure during vacuum degassing and reduces the amount and size of coarse CaO-containing inclusions in the steel. In a manufacturing method for producing highly clean steel by subjecting molten steel containing C, Si, Mn, P, and S to vacuum degassing with a degassing apparatus including a vacuum tank and a dip tube, After the degassing process is completed, supply the gas for return pressure into the vacuum chamber, and when returning the decompressed state in the vacuum chamber to atmospheric pressure, the molten steel that passes through the vacuum chamber and dip tube and descends into the ladle A method for refining molten steel, wherein the descending flow velocity U [m / sec] is controlled to 0.15 m / sec or less to recover the pressure.
