Special novel silicon mullite brick for rotary cement kiln and preparation process of special novel silicon mullite brick
The invention relates to the technical field of refractory materials, and discloses a special novel silicon mullite brick for a rotary cement kiln, which is prepared from the following raw materials in percentage by weight: 30-50% of mullite, 10-20% of SiC, 5-20% of andalusite mineral, 1-10% of alpha-Al2O3, 5-10% of high-quality binding clay, 1-3% of antioxidant and 1-5% of chromite. According to the special novel silicon mullite brick for the rotary cement kiln and the preparation process thereof, the refractory lining brick contains Cr + 3, the Cr + 3 released by the brick in use has the effect of stabilizing beta-C2S in a kiln coating, and the special novel silicon mullite brick has the advantages of high high-temperature strength, excellent alkali-sulfur corrosion resistance, excellent thermal shock stability, good kiln coating stability in use, has the advantages of obviously prolonging the service life of the transition zone of the cement kiln and reducing energy consumption, and solves the problem that the service life of the lining brick is seriously influenced due to the fact that the kiln coating hanging performance is poor, the kiln coating falls off when being hung and the lining brick cannot be well protected when the existing common silicon mullite brick is used.
本发明涉及耐火材料技术领域，且公开了一种水泥回转窑用特种新型硅莫砖，由下述重量百分比的原料制成:莫来石30～50％，SiC10～20％，红柱石族矿物5～20％，α‑Al2O31～10％，优质结合粘土5～10％，抗氧化剂1～3％和铬铁矿1～5％。该水泥回转窑用特种新型硅莫砖及其制备工艺，其耐火衬砖中含有Cr+3，在使用中砖释放的Cr+3有稳定窑皮中β－C2S的作用，具有高温强度高，抗碱硫侵蚀优异，热震稳定性优良，使用中窑皮稳定性好，能显著延长水泥窑过渡带使用寿命和降低能源消耗的优点，解决了现有普通硅莫砖使用时，挂窑皮性能较差，窑皮时挂时落，不能很好的保护衬砖，使衬砖的使用寿命受到严重影响的问题。
