Refractory material as well as preparation method and application thereof
The invention provides a refractory material and a preparation method and application thereof.The refractory material is prepared from a silicon carbide material, graphite, zirconite and a binding agent, and the silicon carbide material comprises first silicon carbide particles, second silicon carbide particles and third silicon carbide particles; the particle size of the first silicon carbide particles is larger than that of the second silicon carbide particles and larger than that of the third silicon carbide particles. The refractory material provided by the invention has excellent corrosion resistance, can specifically solve the problem that hydrogen fluoride and fluorine ions seriously corrode the inner wall of a heat treatment kiln in the process of recovering a lithium battery crushed material by adopting dry heat treatment, prolongs the service life of the kiln, and improves the corrosion resistance of a lining of the kiln.
本发明提供了一种耐火材料及其制备方法与应用，所述耐火材料的制备原料包括碳化硅材料、石墨、锆英石和结合剂，其中，所述碳化硅材料包括第一碳化硅颗粒、第二碳化硅颗粒和第三碳化硅颗粒；所述第一碳化硅颗粒的颗粒尺寸＞第二碳化硅颗粒的颗粒尺寸＞第三碳化硅颗粒的颗粒尺寸。本发明所述耐火材料具备优异的耐腐蚀能力，能够针对性的解决在采用干法热处理回收锂电池破碎料的过程中，氟化氢和氟离子对热处理窑炉内壁腐蚀严重的问题，延长窑炉使用寿命，增加窑炉内衬的耐腐蚀性。
