The experiments were carried out both with a laboratory scale apparatus and 45t industrial ladles. The following results have been obtained; (1) Using LD slag with Fe2O3 powder, the phosphorus level of hot metal can be reduced to 20% to 40% of the initial content after 40 minutes treatment even when the slag is acidic.
