Brown fused alumina brick and preparation process thereof
The invention discloses a brown fused alumina brick and a preparation process thereof, and the key point of the technical scheme is that the brown fused alumina brick is formed by sintering the following components in parts by mass: 3-5 parts of kaolin, 2-4 parts of brown fused alumina fine powder, 1-2 parts of alumina micro powder and 0.3-0.8 part of calcium lignosulphonate; the waste materials comprise the following components in parts by weight: 5-10 parts of electric smelting waste bricks, 0.2-0.8 part of electric smelting mullite and 0.2-0.4 part of glass factory waste zirconium corundum bricks. The brown fused alumina brick is produced and manufactured by adopting waste materials of electronics factories and ceramic enterprises, new raw materials do not need to be produced again, the use effect of the product is better than that of a special-grade high-aluminum material in the market, and the service life of a kiln is prolonged; the preparation process of the brown fused alumina brick has the advantages of simple preparation flow, low production cost, electricity charge saving and resource reutilization.
本发明公开了一种棕刚玉砖及其制备工艺，其技术方案要点是：棕刚玉砖，由以下质量计组分烧结而成，包括：高岭土3‑5份、棕刚玉细粉2‑4份、氧化铝微粉1‑2份、木质素磺酸钙0.3‑0.8份；以及废弃料，所述废弃料包括：电熔废砖5‑10份、电熔莫来石0.2‑0.8份、玻璃厂废锆刚玉砖0.2‑0.4份。本棕刚玉砖采用了电子厂和陶瓷企业废弃料进行生产制造，不用再重新生产新原料，产品使用效果还优于市面上的特级高铝材料，延长了窑炉使用寿命；本棕刚玉砖的制备工艺具有制备流程简单，生产成本低，节约电费，资源也得到重复利用。
