PROBLEM TO BE SOLVED: To provide a treating method of molten steel excellent in the solidification structure characteristic without obstructing the workability and the corrosion resistance, etc., by stably producing MgO or Mg oxide functioned as solidification nuclei when molten steel is solidified, sufficiently fining the solidification structure in a cast slab, restraining the maintenance and the scrapping of the cast slab and the steel material and improving the quality. ;SOLUTION: In the treating method of the molten steel for fining the solidification structure in the cast slab, before adding Mg into the molten steel 14, an Al-containing alloy is added into the molten steel 14 to perform a deoxidation treatment.;COPYRIGHT: (C)2001,JPO
