<P>PROBLEM TO BE SOLVED: To provide a chromium-free monolithic refractory which, when used for the lining of a melting furnace, exhibits durability equal to or better than that of an alumina-chromia monolithic refractory. <P>SOLUTION: The chromium-free monolithic refractory for a waste melting furnace is prepared by adding a binder and a dispersant to a refractory material composition containing an alumina material and a titania. The refractory contains at least 90 mass% Al<SB>2</SB>O<SB>3</SB>, 0.1-5 mass% (in terms of TiO<SB>2</SB>) titania, and less than 5 mass% other components or contains at least 80 mass% Al<SB>2</SB>O<SB>3</SB>, 0.1-5 mass% (in terms of TiO<SB>2</SB>) titania, at most 15 mass% Y<SB>2</SB>O<SB>3</SB>, and less than 5 mass% other components. A waste melting furnace with a lining formed from the chromium-free monolithic refractory is also provided. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
