| titleOfInvention | Refractory material for furnace wall above liquid line of non-ferrous smelting melting furnace and preparation method thereof |
| abstract | A refractory material for a furnace wall above a liquid line of a nonferrous smelting and melting furnace is suitable for the position of the furnace wall above the liquid line of the nonferrous smelting and melting furnace, and comprises the following components: the aluminum-chromium eutectic, aluminum-magnesium spinel, hercynite and a bonding agent. The invention uses aluminum-chromium eutectic, aluminum-magnesium spinel and hercynite as raw materials, thereby reducing the frying temperature and the volatilization of chromium sesquioxide. Meanwhile, clay, phosphoric acid solution, aluminum dihydrogen phosphate solution and water are used as a bonding agent, so that the slag resistance and the permeation resistance of the refractory material are enhanced. The phosphoric acid solution reacts with alumina in the refractory material to generate phosphoric acid bonds to form a certain network structure, and the addition of the clay leads part of raw materials to be melted together with the clay during firing to fill larger intercrystalline gaps, while the viscosity of the aluminum dihydrogen phosphate is larger, thus enhancing the bonding effect of the clay binder and finally leading the refractory material to be more compact. |
