Abstract: An alloy steel containing chromium is refined by blowing fluids into the molten steel through double or triple feed tuyeres. Each tuyere first provides a flow of an oxidizing fluid, a second flow of a fluid for diluting the carbon monoxide in the bath and a third peripheral flow of a carbon make-up liquid.
