<p>An environmentally friendly flux for molten steel desulfurization includes CaO and Al 2 O 3 so that [CaO]/[Al 2 O 3 ] is within a range of 1.6 to 3.0, and includes one or more alkali metal oxides of Na 2 O, K 2 O, and Li 2 O, and SiO 2 so that [SiO 2 ]/[R 2 O] is within a range of 0.1 to 3, [R 2 O] is within a range of 0.5 mass% to 5 mass%, and [SiO 2 ] is within a range of 0.05 mass% to 15 mass% in a case in which the [CaO], the [Al 2 O 3 ], the [SiO 2 ], and the [R 2 O] represent the mass% of CaO, the mass% of Al 2 O 3 , the mass% of SiO 2 , and the total amount of the mass% of Na 2 O, the mass% and K 2 O, mass% of Li 2 O respectively.</p> |
