| titleOfInvention | Chromium-free brick for high-temperature zone of dry-process cement kiln and preparation method thereof |
| abstract | A preparation method of a chromium-free brick for a high-temperature zone of a dry-method cement kiln belongs to the technical field of refractory materials. The formula is characterized by comprising the following raw materials in parts by weight: 2.68-3.22 parts of calcium zirconate, 1.67-2.31 parts of zirconium material, 1.72-2.52 parts of magnesium aluminate spinel and 91-94 parts of magnesium brick base material. The process comprises the steps of material preparation, mixing, hydraulic forming, drying and firing; the drying system is that the temperature of the vehicle outlet end is 70-100 ℃, and the temperature of the vehicle inlet end is as follows: 30-50 ℃; the cart speed is 1.5-2.5 h/cart, and the residual moisture after drying is less than 2.0%; the firing system in the firing step is as follows: raising the temperature to 195-205 ℃ at room temperature, preserving the heat for 7.5-8.5 h, continuously raising the temperature to 985-1004 ℃, and preserving the heat for 3.5-4.5 h for the second time. The environment-friendly chromium-free alkaline refractory brick has excellent physical and chemical properties, particularly kiln coating hanging property of a refractory brick of a firing zone, and obviously improved clinker erosion resistance. |
