| titleOfInvention | Melting loss control method for gas injection lance |
| abstract | An object of the present invention is to reduce the melting loss of a lance more than before. A method of suppressing the erosion of a gas blowing lance (2) for blowing a gas into a molten metal (6) in a ladle (1), which comprises adding Al 2 O 3 to the molten metal (6). Source and MgO source are at least introduced, and the concentration of Al 2 O 3 in the slag (7) generated on the surface of the molten metal (6) is 24 wt% or more and 30 wt% or less, and the concentration of MgO in the slag is 10 wt% Adjust to at least 15% by weight.
