<p>PROBLEM TO BE SOLVED: To provide a method for effectively using fly ash and iron-containing waste material by which the fly ash and the iron-containing waste material, produced in large quantities in iron works can effectively be used as resources. SOLUTION: After mixing the fly ash with the iron-containing waste material such as iron oxide scale, scarfing waste of iron and steel cast slab, this mixture is granulated to make a briquette, and this briquette is charged onto molten iron or molten steel, and the yield of the iron is improved by adjusting the basicity of the molten slag, and also, reducing iron oxides in the iron-containing waste material.</p> |
