The invention relates to the technical field of castables, particularly to a calcium hexaluminate non-stick aluminum castable, which is composed of the following components: 57-75 parts of calcium hexaluminate aggregate, 10-15 parts of calcined alumina, 5-10 parts of alumina cement, 10-15 parts of white corundum, and 0.1-0.15 part of a water reducing agent. According to the invention, through reasonable formula design, the calcium hexaluminate castable prepared on the premise of not adding a molten aluminum wetting agent has excellent compressive strength, compressive strength and molten aluminum permeation resistance, so that the problem that a wetting agent needs to be added into an existing molten aluminum castable to improve the molten aluminum permeation resistance, the environmentalproblem caused by adding the wetting agent and the problem of injuring the body of an aluminum melting operator are solved, and the problems that stirring dispersion is difficult, construction stirring is difficult to uniform and the like caused by adding the wetting agent are solved.
本发明涉及浇注料技术领域，尤其涉及一种六铝酸钙不沾铝浇注料，由如下组分组成:六铝酸钙骨料57～75份；煅烧氧化铝10～15份；氧化铝水泥5～10份；白刚玉10～15份；减水剂0.1～0.15份，本发明通过合理的配方设计，在不添加铝液湿润剂的前提下制备的六铝酸钙浇注料具有优异的耐压强度、抗压强度以及抗铝液渗透性能，从而避免了现有熔铝浇注料中需要添加湿润剂来提高抗铝液渗透能力的问题，以及因添加湿润剂所带来的环境问题和对熔铝操作工身体造成的伤害问题，同时避免了因添加湿润剂所带来的搅拌分散难，施工搅拌均匀难等问题。
