Special low-aluminum mullite brick for lithium salt rotary kiln and preparation method of special low-aluminum mullite brick
The invention relates to the technical field of refractory materials, and discloses a special low-aluminum mullite brick for a lithium salt rotary kiln and a preparation method thereof.The special low-aluminum mullite brick is prepared from, by weight, 50%-60% of fused mullite, 18%-20% of converter 85 materials, 6%-8% of Guangxi white mud, 10%-14% of silicon carbide and 5%-6% of additives, the particle size composition of the electric smelting mullite is as follows: 10 to 15 percent of electric smelting mullite with the particle size of 5 to 3mm and 14 to 17 percent of electric smelting mullite with the particle size of 3 to 1mm. According to the special low-aluminum mullite brick for the lithium salt rotary kiln and the preparation method of the special low-aluminum mullite brick disclosed by the invention, the problems that a high-aluminum and silicon-mullite refractory kiln lining for the existing lithium salt rotary kiln is poor in lithium salt slag corrosion resistance and is easy to react with raw materials in a roasting process are solved; according to the lithium salt rotary kiln built by the special low-aluminum mullite bricks, the refractory lining material for the lining is relatively low in melting loss rate and does not react with the raw materials at high temperature, so that the service life of the kiln lining can be obviously prolonged.
本发明涉及耐火材料技术领域，且公开了一种锂盐回转窑用特种低铝莫来石砖及其制备方法，所述该特种低铝莫来石砖由下述重量百分比的原料制成：电熔莫来石50～60％、转炉85料18～20％、广西白泥6～8％、碳化硅10～14％、添加剂5～6％，所述电熔莫来石的粒度组成为：5～3mm电熔莫来石10～15％、3～1mm电熔莫来石14～17％。该锂盐回转窑用特种低铝莫来石砖及其制备方法，本发明的特种低铝莫来石砖解决了现有锂盐回转窑用高铝质及硅莫质耐火窑衬的抗锂盐渣侵蚀差、焙烧过程中易与生料反应的问题，该特种低铝莫来石砖砌筑的锂盐回转窑其内衬用耐火衬料熔损速率较低，且在高温下不与生料发生反应，能明显延长窑衬的使用寿命。
