Anorthite lightweight refractory material not prone to cracking and preparation method thereof
The invention provides a anorthite light refractory material not prone to cracking and a preparation method thereof. The anorthite light refractory material is prepared from 48-55wt% of coal gangue, 3-6wt% of kyanite, 4.5-6.5wt% of pyrophyllite, 10-14.5wt% of refractory clay, 9.5-15.5wt% of calcium carbonate, 5-10wt% of high-alumina cement, 1-3wt% of zirconium-containing fibers and 3-8wt% of an additive, wherein the content of Al2O3 in the zirconium-containing fiber is 35-50wt%, and the content of zirconium in the zirconium-containing fiber is 14-20wt%; and the particle size of the refractoryclay is 300-400 meshes, and the particle size of the calcium carbonate is 550-650 meshes. By adjusting the grain composition of the raw materials used by the anorthite refractory material and cooperatively using the zirconium-containing fibers, the internal structure of the prepared anorthite cast brick is more compact after being sintered, so that the anorthite cast brick has higher compressive strength and is not easy to crack.
本发明提供一种不易开裂的钙长石轻质耐火材料及其制备方法，由以下原料制备得到：48～55wt％的煤矸石、3～6wt％的蓝晶石、4.5～6.5wt％的叶腊石、10～14.5wt％的耐火粘土、9.5～15.5wt％的碳酸钙、5～10wt％的高铝水泥1～3wt％的含锆纤维和3～8wt％的助剂；所述含锆纤维中Al2O3含量为35～50wt％，锆含量为14～20wt％；所述耐火粘土的粒径为300～400目，所述碳酸钙的粒径为550～650目。本发明通过调整钙长石耐火材料所用原料的颗粒级配，同时配合使用含锆纤维，使制得的钙长石浇注砖烧后内部结构更加密实，进而耐压强度更高，不易开裂。
