The invention discloses a calcium dialuminate non-stick aluminum castable which comprises the following raw materials in percentage by weight: a component A and a component B. The component A comprises the following components in percentage by weight: 50-70% of calcium dialuminate particles and 10%-20% of calcium dialuminate fine powder; the component B comprises the following components in percentage by weight: 5-7% of calcined alumina micro-powder, 0-10% of 320-mesh tabular corundum or white corundum powder, 5-10% of activated aluminum oxide and 3-5% of alumina cement. According to the castable, reasonable formula design is adopted; the calcium dialuminate castable prepared on the premise of not adding a molten aluminum wetting agent has excellent thermal insulation property, compressivestrength, compressive strength and molten aluminum permeation resistance; the castable has the advantages of large formula design expansibility, simple production process, low energy consumption, easy quality control, convenient construction, small environmental pollution and low raw material cost, is suitable for any part in contact with molten aluminum, and is suitable for wide popularization and application in the molten aluminum industry.
本发明公开了一种二铝酸钙不沾铝浇注料，其原料按重量百分比计包括A组分和B组分，其中，所述A组分包括：二铝酸钙颗粒50～70%；二铝酸钙细粉10～20%；所述B组分包括：煅烧氧化铝微粉5～7%；320目板状刚玉或白刚玉粉0～10%；活性氧化铝5～10%；氧化铝水泥3～5%。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二铝酸钙浇注料具有优异的保温性能、耐压强度、抗压强度以及抗铝液渗透性能，本发明的配方设计扩展度大，生产工艺简单，能耗低，质量容易控制，施工方便，适用于和熔融铝液接触的任何部位，且对环境的污染小、原料成本低廉，适于在熔铝行业的广泛推广应用。
