The invention provides a light-weight anorthite refractory material and a preparation method thereof. In the invention, the anorthite brick product is prepared by formulating the raw materials and components, cooperating with secondary stirring and subsequent drying and roasting Compared with the content of alumina, calcium oxide and silicon oxide in the raw materials during batching, the content of alumina, calcium oxide and silicon oxide in the compound will not fluctuate greatly, and will not affect the performance of the product. Moreover, the anorthite refractory material (especially the anorthite refractory brick) in the present invention has a uniform pore size distribution, a closed-cell structure, a controllable volume density of 480±50kg/m 3 , and good compressive strength and excellent thermal conductivity. |
