METHOD AND APPARATUS FOR THE RECOVERY OF THE SECONDARY METALLURGY (LF) SLAG AND ITS RECYCLING IN THE STEEL PRODUCTION PROCESS BY MEANS OF ELECTRIC ARC FURNACE

摘要

A method for the recovery of the secondary metallurgy (LF) slag from a plant for the production of steel comprises a cooling step of the slag, by means of the passage of air and/or other gas, a breakdown step, i.e. transformation of several phases present in the mass into powder and a step of drawing the powder.
