Method for sintering and synthesizing mullite by using coal gangue as raw material
The invention relates to the technical field of refractory materials, in particular to a method for sintering and synthesizing mullite by taking coal gangue as a raw material, which comprises the following steps: step 1, preparing 50-55 parts of coal gangue, 15-22 parts of sillimanite, 8-12 parts of basalt, 5-7 parts of magnesite, 0.01-0.02 part of aluminum hydroxide, 3-4 parts of glass powder, 2-4 parts of sintering aid, 5-7 parts of coal and 3-5 parts of zirconium oxide; 2, ball-milling the coal gangue powder, sillimanite, basalt, magnesite, aluminum hydroxide, glass powder, a sintering aid, coal and zirconium oxide through a ball mill to obtain a mixed fine material; 3, forming by a hydraulic machine; and step 4, sintering the mixed fine material through a tunnel kiln to obtain mullite. The synthesis method is simple in process and high in utilization rate, industrial production is easy to realize, and coal gangue is expected to be converted into a low-cost and large-reserve mineral resource.
本发明涉及耐火材料技术领域，具体涉及一种以煤矸石为原料去烧结合成莫来石的方法，其包括以下步骤：步骤一、准备煤矸石50‑55份、硅线石15‑22份、玄武岩8‑12份、菱镁矿5‑7份、氢氧化铝0.01‑0.02份、玻璃粉3‑4份、烧结助剂2‑4份、煤炭5‑7份、氧化锆3‑5份；步骤二、通过球磨机对准备煤矸份、硅线石、玄武岩、菱镁矿、氢氧化铝、玻璃粉、烧结助剂、煤炭、氧化锆进行球磨，获得混合细料；步骤三、液压机成型；步骤四、通过隧道窑对所述混合细料进行烧结，获得莫来石。该合成方法工艺简单，且利用率高，容易实现工业化生产，有望将煤矸石转变成为一种成本低且储量大的矿产资源。
