Torsion-resistant wear-resistant refractory brick for rotary cement kiln and preparation method of torsion-resistant wear-resistant refractory brick
The invention provides a torsion-resistant wear-resistant refractory brick for a rotary cement kiln and a preparation method of the torsion-resistant wear-resistant refractory brick. The torsion-resistant wear-resistant refractory brick is prepared from the following components in percentage by weight: 10-16% of synthetic medium aluminum clinker with the particle size of 5-3mm, 10-16% of zirconium dioxide powder, 10-16% of plastic clay powder, 10-16% of ferro-silicon nitride powder, 10-16% of alpha-alumina powder and the balance of a binding agent, the particle size is 3 to 1.5 mm, and the content is 28 to 39 percent; the particle size is 1.5 to 0.074 mm, and the content is 8 to 14 percent; the particle size is less than 0.074 mm, and 29-32%; the high-strength wear-resistant ceramic is prepared from the following components in percentage by weight: 3 to 11 percent of zirconium dioxide powder, 2 to 9 percent of plastic clay powder, 3 to 9 percent of ferro-silicon nitride powder, 3 to 8 percent of alpha-aluminum oxide powder and 3 to 5 percent of an additional binding agent. The torsion-resistant and wear-resistant refractory brick for the rotary cement kiln is prepared by optimizing and comparing different raw materials, selecting proper raw materials and adopting scientific grain composition, has good torsion resistance and tensile resistance in a rotating kiln body, also has a wear-resistant function, and has the most prominent characteristics that the load of the kiln body is reduced, the service life of the kiln body is prolonged, and the service life of the kiln body is prolonged. And compared with a traditional refractory brick, the load is reduced by 23%, the temperature of the cylinder is reduced by 46%, and the economic benefit and the social benefit are outstanding.
本申请提供了一种水泥回转窑用抗扭拉耐磨耐火砖及其制备方法，由合成中铝熟料、二氧化锆粉、可塑粘土粉、氮化硅铁粉、α‑氧化铝粉、结合剂按如下百分比配置而成：合成中铝熟料：粒度5‑3mm，10‑16％；粒度3‑1.5mm，28‑39％；粒度1.5‑0.074mm，8‑14％；粒度＜0.074mm，29‑32％；二氧化锆粉3‑11％，可塑粘土粉2‑9％，氮化硅铁粉3‑9％，α‑氧化铝粉3‑8％，外加结合剂3‑5％。本申请通过对不同原料的优化对比，选择适合的原材料，采用科学的颗粒级配，制备出一种水泥回转窑用抗扭拉耐磨耐火砖，在转动的窑体内，具有很好的抗扭转和抗拉伸性能，同时又有耐磨的功能，最突出的特点是使窑体载荷下降，热损失减少，比传统耐火砖降低负荷23％，筒体温度降低46％，经济效益和社会效益突出。
