Abstract：The pellet containing carbon, which could be self-reduced using the carbon as reductant, was made from the dust and mud in iron and steel industry. The dust and mud pellets were warmed-up by the residual heat in torpedo ladle, and then self-deoxidization processes of the pellets were carried out after accepting the hot metal. Ferric in dust and mud was recycled, which had no effect on steel-making. This method has been widely used in Ansteel. Recently, a few foaming slag, which affected the routine, was found in some torpedo ladle. The reasons of the formation of foaming slag and the control methods were summarized through both theory analysis and experiments.
