Silicon carbide ceramic tertiary air flashboard suitable for being installed close to kiln head and preparation method of silicon carbide ceramic tertiary air flashboard
The invention belongs to the technical field of tertiary air flashboards, and discloses a silicon carbide ceramic tertiary air flashboard suitable for being installed close to a kiln head and a preparation method of the silicon carbide ceramic tertiary air flashboard. The silicon carbide ceramic refractory slurry comprises the following raw materials in percentage by mass: 70-90% of silicon carbide, 1-5% of a binding agent A, 7-20% of alumina micro powder, 1-6% of a binding agent B, an additive accounting for 0.2-0.4% of the total mass of the raw materials and water accounting for 1-6% of the total mass of the raw materials, wherein the binding agent A is composed of graphite and silica sol, and the binding agent B is composed of calcium acetate, water and pseudo-boehmite fine powder. The silicon carbide ceramic tertiary air flashboard has the advantages of high strength, wear resistance and the like, the service life of the silicon carbide ceramic tertiary air flashboard can reach 18-24 months when the silicon carbide ceramic tertiary air flashboard is mounted close to a kiln head, the use effect of the flashboard at the position is greatly improved, tertiary air is controlled more flexibly and more accurately, the product stability is improved, and long-term stable operation of a cement kiln is guaranteed.
本发明属于三次风闸板技术领域，公开了一种适用于靠近窑头安装的碳化硅陶瓷三次风闸板及其制备方法，其闸板主体由碳化硅陶瓷耐火浆料注浆成型后烧结而成，该碳化硅陶瓷耐火浆料包括以下质量百分比的原料：碳化硅70～90％、结合剂A 1～5％、氧化铝微粉7～20％、结合剂B 1～6％，以上原料之和为100％，并外加以上原料总质量0.2～0.4％的添加剂和1～6％的水；其中，结合剂A由石墨和硅溶胶组成，结合剂B由乙酸钙、水和拟薄水铝石细粉组成。本发明碳化硅陶瓷三次风闸板具有高强、耐磨等优点，在靠近窑头部位安装使用寿命能够达到18～24个月，极大地改善了该部位闸板的使用效果，实现更灵活、更精准地控制三次风，提高产品稳定性，保障水泥窑长期稳定运行。
