<p>PURPOSE:To utilize Al residual ash as a heat generating or insulating material or a slag forming material during steel manufacture by mixing the ash with vegetable fibers, a water soluble binder and water and molding the mixture to a proper shape and size. CONSTITUTION:About 100pts.wt. finely powdered Al residual ash (Al ash) is mixed and kneaded with about 1-10pts.wt. vegetable fibers such as paper pulp or pulp recovered from wastepaper, about 0.5-5pts.wt. org. water soluble binder such as CMC or corn starch and about 10-30pts.wt. water. The mixture is filled into molds after being kneaded and molded or extrusion-molded and the resulting pellets or briquettes are cut to a proper size and used. Thus, the hardly utilizable finely powdered Al residual ash is wet-granulated without causing foaming and expansion due to generated gaseous ammonia and the granulated ash can be utilized as a heat generating or insulating material or a slag forming material during steel manufacture.</p> |
