Quick-drying explosion-proof high-strength wear-resistant castable
The invention discloses a quick-drying explosion-proof high-strength wear-resistant castable which comprises the following components in percentage by weight: 24-30% of GL-85 bauxite of 5-3 mm, 20-24%of GL-85 bauxite of 3 to 1mm, 8-12% of GL-85 bauxite of 1 to 0mm, 8-12% of 90 black silicon carbide of 1-0mm, 6-10% of 90 black silicon carbide of less than or equal to 0.088 mm, 15-20% of 93 brown fused alumina powder of less than or equal to 0.088 mm, 2-6% of 92 silica powder, 4-6% of alpha-Al2O3 micro powder, 4-7% of aluminate cement, 1.0-1.5% of steel fiber of 3-5 mm, 0.06%-0.10% of a composite explosion-proof agent, and 0.20-0.40% of a composite additive. According to the invention, 85 bauxite and silicon carbide are used as main materials, and superfine powder is used for combination, so that reasonable grain composition is determined, and on the premise of ensuring wear resistance, densest accumulation, good flowability and convenience in construction are achieved. Meanwhile, the metal aluminum powder and the explosion-proof fibers are added as a composite explosion-proof agent, so that burst during baking is effectively avoided, and the use safety and reliability are greatly enhanced.
本发明公开了一种快干防爆型高强耐磨浇注料，一种快干防爆型高强耐磨浇注料，它包括以下重量百分数的组分：GL‑85铝矾土5～3mm，24～30％；GL‑85铝矾土3～1mm，20～24％；GL‑85铝矾土1～0mm，8～12％；90黑碳化硅1～0mm，8～12％；90黑碳化硅≤0.088mm，6～10％；93棕刚玉粉≤0.088mm，15～20％；92硅微粉，2～6％；α‑Al2O3微粉，4～6％；铝酸盐水泥，4～7％；钢纤维3～5mm，1.0～1.5％；复合防爆剂0.06～0.10％；复合添加剂0.20～0.40％，本发明以85铝矾土、碳化硅作为主体材料，使用超微粉结合，确定了合理的颗粒级配，在能保证耐磨性的前提下，达到最密堆积，具有良好流动性，便于施工。同时添加金属铝粉、防爆纤维作为复合防爆剂，有效避免烘烤中发生爆裂，大大增强了使用安全可靠性。
