High-strength erosion-resistant ladle self-flow castable and preparation method thereof
The invention provides a high-strength erosion-resistant ladle self-flow castable and a preparation method thereof. And steel ladle self-flowing castable is calculated according to parts by mass. Thepreparation raw materials comprise the following components in parts by weight: 5-40 parts of chromium corundum aggregate, 20-70 parts of washed corundum aggregate, 5-40 parts of white corundum fine powder, 1-15 parts of fused magnesite fine powder, 1-25 parts of low-sodium alpha alumina micro powder, 110 parts of pure calcium aluminate cement, 0.1-5 part of zirconium composite silicon micro powder, 0.1-5 part of a delayed coagulation type water reducing agent and 0.01-0.5 part of organic fibers. The self-flow castable has high strength, good erosion resistance and slag erosion resistance, andcan solve the problems of poor fluidity, segregation, no erosion resistance, no erosion resistance and the like of corundum self-flow castables in the use process.
本发明提供一种高强度抗冲刷侵蚀钢包自流浇注料及其制备方法，钢包自流浇注料按照质量份数计算，其制备原料包括以下组分：铬刚玉骨料5‑40份、水洗刚玉骨料20‑70份、白刚玉细粉5‑40份、电熔镁砂细粉1‑15份、低钠α氧化铝微粉1‑25份、纯铝酸钙水泥1‑10份、锆复合硅微粉0.1‑5份、缓凝型减水剂0.1‑5份、有机纤维0.01‑0.5份。该自流浇注料具有较高的强度、良好的抗冲刷性能和抗渣侵蚀性能，可解决刚玉质自流浇注料在使用过程中存在的流动性差、偏析、不耐冲刷和侵蚀等问题。
