Mullite burner brick and preparation method thereof
The invention discloses a mullite burner brick which is prepared from the following raw material components in percentage by weight: 25 to 35 percent of electro-fused mullite with the particle size of 1.1 to 3mm, 30 to 40 percent of electro-fused mullite with the particle size of 0.1 to 1mm, 20 to 30 percent of 200-mesh electro-fused mullite, 5 to 10 percent of 200-mesh special-grade carclazyte and 1.5 to 2 percent of an organic binding agent. Comprising the following steps that S1, an organic binding agent and water are prepared into a solution according to the weight ratio of 1: 4; s2, adding the large-particle-size fused mullite into a wet mill for mixing and milling; s3, adding the solution obtained in the step S1 into a wet mill for continuous mixing and milling; s4, adding 200-mesh fused mullite and special-grade carclazyte into a wet mill for mixing and milling; S5, aging the mixed and milled materials; and S6, mixing and grinding the aged material again, and firing and molding. By selecting mullite with different finenesses and adopting an aging process in the preparation process, the flowability and plasticity of the material are improved, the consistency of subsequent green brick density is improved, and the service life of the burner brick is longer.
本发明公开了一种莫来石烧咀砖，按重量百分数计，包括以下原料组分：粒径为1.1‑3mm的电熔莫来石25‑35%、粒径为0.1‑1mm的电熔莫来石30‑40%、200目的电熔莫来石20‑30%、200目的特级白土5‑10%、有机结合剂1.5‑2%，一种莫来石烧咀砖的制备方法，包括以下步骤：S1、将有机结合剂与水按重量比1:4的比例配制溶液；S2、将大粒径的电熔莫来石加入湿碾机中混碾；S3、将S1步骤的溶液加入湿碾机中继续混碾；S4、将200目的电熔莫来石、特级白土加入湿碾机中混碾，S5、将混碾后的物料陈腐；S6、将陈腐后的物料再次混碾并烧制成型。通过选用不同细度的莫来石，并在制备过程中采用陈腐工艺，提高物料的流动性和可塑性，提高后续砖坯密度的一致性，使烧咀砖的寿命更长。
