Iron runner castable containing modified explosion-proof fibers and preparation method of iron runner castable
The invention discloses an iron runner castable containing modified explosion-proof fibers and a preparation method of the iron runner castable. Comprising the following components: 4 to 10 weight percent of dense corundum fine powder, 3 to 8 weight percent of active alpha-Al2O3 micro powder, 1.5 to 4.5 weight percent of silicon micro powder, 12 to 25 weight percent of silicon carbide, 1.5 to 3 weight percent of calcium aluminate cement, 1.5 to 4 weight percent of a carbon source, 2 to 3.5 weight percent of a submicron composite antioxidant, 0.15 to 0.4 weight percent of modified explosion-proof fiber, 0.1 to 0.2 weight percent of metal aluminum powder, 0.05 to 0.2 weight percent of a polycarboxylate dispersant and the balance of brown corundum particles. The modified explosion-proof fiber is obtained by modifying the thermoplastic organic fiber, the bursting resistance of the castable prepared from the modified explosion-proof fiber is remarkably improved, and the mechanical property, the slag corrosion resistance and the oxidation resistance of the castable are also improved; meanwhile, the modified explosion-proof fibers cannot fly around in the dry mixing process of the castable, the dispersity is good, and penetrating air holes cannot be formed in a matrix after high-temperature pyrolysis or ablation.
本发明公开了一种含改性防爆纤维的铁沟浇注料及其制备方法，该浇注料按质量百分比计，包括以下组分：4‑10wt％的致密刚玉细粉、3‑8wt％的活性α‑Al2O3微粉、1.5‑4.5wt％的硅微粉、12‑25wt％的碳化硅、1.5‑3wt％的铝酸钙水泥、1.5‑4wt％的碳源、2‑3.5wt％的亚微米复合防氧化剂、0.15‑0.4wt％的改性防爆纤维、0.1‑0.2wt％的金属铝粉、0.05‑0.2wt％的聚羧酸盐类分散剂，余量为棕刚玉颗粒。本发明通过对热塑性有机纤维进行改性处理得到改性防爆纤维，使用其制得的浇注料的抗爆裂性能得到显著改善，浇注料的力学性能、抗渣侵蚀性能和抗氧化性能也得到了提高；同时改性后的防爆纤维在浇注料干混过程中不会四处飘扬、分散性好，高温裂解或烧蚀后也不会在基质中形成贯穿气孔。
