PROBLEM TO BE SOLVED: To provide a formed refractory material free from chromium, having excellent corrosion resistance, slug infiltration resistance and spalling resistance and suitable for the furnace for melting waste material. SOLUTION: The objective formed refractory material is produced by compounding 100 pts. of a refractory composition with 0.5-3.5 pts. of sodium aluminate in terms of NaAlO2 and 0.1-1.3 pts. of sorbitol. The sum of spinel particle and dolomite particle in the refractory composition is 80-96% and the amount of fused zirconia particle containing glassy phase is 4-20%. |
