Double-chamber lime kiln body structure, composite mullite brick for kiln body and preparation method of composite mullite brick
The invention relates to the technical field of mullite bricks, and particularly discloses a double-chamber lime kiln body structure, a composite mullite brick for a kiln body and a preparation method of the composite mullite brick. The composite mullite brick for the kiln body is mainly prepared from the following raw materials: mullite fine powder, aluminum factory waste residues, silica fume, a binding agent, a pore forming agent, a reinforcing agent and an auxiliary agent, the reinforcing agent is prepared from silicon carbide, silicon nitride and tantalum carbide, and the auxiliary agent is at least two of calcium hexaluminate, kyanite and dolomite; the preparation method comprises the following steps: mixing and grinding the raw materials to obtain a mixture; pressing the mixture into a green brick; and drying and calcining the green brick to obtain the product. The mullite brick prepared by the invention is high in strength and good in thermal shock resistance.
本申请涉及莫来石砖技术领域，具体公开了一种双膛石灰窑体结构、窑体用复合莫来石砖及其制备方法。本申请的窑体用复合莫来石砖，主要由如下原料制成：莫来石细粉、铝厂废渣、微硅粉、结合剂、造孔剂、增强剂、辅助剂，增强剂由碳化硅、氮化硅、碳化钽组成，辅助剂为六铝酸钙、蓝晶石、白云石中的至少两种；制备方法，包括如下步骤：将上述原料混碾，得到混合料；将混合料压制成砖坯；将砖坯干燥、煅烧，即得。本申请制得的莫来石砖强度高，热震稳定性佳。
