Recycling of ladle slag in the EAF: improvement of the

A new technique is presented to recycle ladle slag within the electric arc furnace through the injection system. The dilution of the chemical species contained in the slag and their combination with the species featuring the EAF slag afford a double advantage: the final slag is structured by chemical species that do not lead to the formation of powders and better stabilize the foaming slag.
