High-temperature sintered Al-Al2O3 sliding plate brick added with titanium concentrate and production method of high-temperature sintered Al-Al2O3 sliding plate brick
The invention relates to a high-temperature sintered Al-Al2O3 sliding plate brick added with titanium concentrate and a production method thereof, and the high-temperature sintered Al-Al2O3 sliding plate brick comprises the following raw materials: 46-62% of tabular corundum, 10-20% of fused compact corundum, 6-10% of activated alumina micro powder, 5-8% of silicon carbide micro powder, 7-10% of titanium concentrate, 4-8% of metal aluminum powder and 1-3% of boron glass powder. Phenolic resin accounting for 3-4% of the total weight of the raw materials and boron modified phenolic resin powder accounting for 1-2% of the total weight of the raw materials are The apparent porosity of the product is 5-8%, the volume density is 3.10-3.20 g/cm < 3 >, the normal-temperature compressive strength is 160-260 MPa, the normal-temperature breaking strength is 25-36 MPa, and the high-temperature breaking strength is 25-35 MPa; and the product has good density and strength. The sliding plate brick disclosed by the invention is relatively low in carbon content and only contains compound carbon SiC and resin residual carbon, and the product does not need to be impregnated with asphalt and subjected to dry distillation after being sintered, so that the environmental pollution caused by volatilization of the asphalt in the production and use processes is avoided.
本发明涉及一种添加钛精矿的高温烧成Al‑Al2O3滑板砖及其生产方法，原料为：46‑62％板状刚玉、10‑20％电熔致密刚玉、6‑10％活性氧化铝微粉、5‑8％碳化硅微粉、7‑10％钛精矿、4‑8％金属铝粉、1‑3％硼玻璃粉，外加上述原料总重量3‑4％的酚醛树脂、1％‑2％硼改性酚醛树脂粉。该产品显气孔率5‑8％、体积密度3.10‑3.20g/cm3、常温耐压强度160‑260MPa、常温抗折强度25‑36MPa，高温抗折强度25‑35MPa；产品致密度和强度较好。本发明的滑板砖碳含量较低，仅含有化合碳SiC及树脂残碳，且产品烧成后无需浸渍沥青和干馏，避免了在生产和使用过程中沥青挥发对环境的污染。
