High-strength anti-skinning refractory castable and preparation method thereof
The invention discloses a high-strength anti-skinning refractory castable and a preparation method thereof, relates to the technical field of refractory castable, and solves the technical problems that SiC is added into the refractory castable in the prior art, and SiO2 gas generated after the SiC is oxidized can form part of air holes in the castable, so that the strength and the volume density of the castable are influenced. The high-strength anti-skinning refractory castable comprises the following components in percentage by mass: 50-80% of waste high-aluminum electrical porcelain, 3-8% of high-alumina bauxite, 10-20% of silicon carbide, 2-8% of alpha alumina micro powder, 2-5% of silica powder, 2-10% of aluminate cement, 0.05-0.1% of a composite explosion-proof material, 0.2-0.5% of an additive and 3-10% of a biological capsule, the bacillus and the calcium lactate are positioned in the capsule film and are wrapped and covered by the capsule film. Compared with the prior art, after the high-strength anti-skinning refractory castable disclosed by the invention uses the biological capsule, the strength and the volume density of the refractory castable can be improved.
本发明公开了一种高强抗结皮耐火浇注料及其制备方法，涉及耐火浇注料技术领域，解决了现有技术中耐火浇注料中添加有SiC，SiC氧化后产生的SiO2气体会使浇注料中形成部分气孔，影响浇注料的强度和体积密度的技术问题。本发明的高强抗结皮耐火浇注料，包括如下质量百分数的组分：废高铝电瓷50～80％，高铝矾土3～8％，碳化硅10～20％，α氧化铝微粉2～8％，硅微粉2～5％，铝酸盐水泥2～10％，复合防爆材料0.05～0.1％，外加剂0.2～0.5％，生物胶囊3～10％，其中，生物胶囊包括胶囊膜、芽孢杆菌和乳酸钙，芽孢杆菌和乳酸钙位于胶囊膜内并被胶囊膜包裹覆盖。相比于现有技术，本发明的高强抗结皮耐火浇注料使用生物胶囊后，可提升耐火浇注料的强度和体积密度。
