A SYSTEM FOR STABILIZATION OF STEEL MAKING (BOF) SLAG THROUGH HYDRATION TREATMENT AND A METHOD OF SUCH STABILIZATION

摘要

The present invention relates to a system for stabilization of Steel Making (BOF) slag through hydration treatment using saturated steam and method for such stabilization. More particularly, the present invention is directed to provide a system for accelerated primary stabilization of BOF slag using steam as medium of stabilization through hydration, by introduction of saturated steam at predetermined pressure and temperature into a pressure vessel such as to induce penetration of steam into the slag sample and thereby stabilize the slag. The system and method to stabilize Steel Making (BOF) slag monitors the progress of the hydration reaction through surrogate parameters of pH and alkalinity which when stabilized can be used as indicator of end point of reaction and therefore can be used as an indicator of stabilization of BOF slag involving the stabilization of free lime at reduced level avoiding the conventional technical limitation of expansion of BOF slag and thus rendering the slag suitable for further use/reuse for variety of applications.
