Chromium free amorphous refractory for waste melting furnace and waste melting furnace containing the same |
| abstract |
The present invention is to provide a solvent-resistant chromium-free amorphous amorphous refractories comparable to chromium oxide-containing products as interiors of a melting furnace, and a chrome-free amorphous refractory material for waste melting furnaces of the present invention. It is composed of yttria raw material and alumina raw material as main material as the composition of fire-resistant raw material, and has the composition of Y 2 O 3 : 0.3 ~ 15 mass% and Al 2 O 3 : 85 mass% or more. |
