Anti-erosion magnesium refractory mortar for steel ladle
The invention provides anti-erosion magnesium refractory mortar for a steel ladle. The anti-erosion magnesium refractory mortar comprises the following raw materials in parts by weight: 70-85 parts of magnesia, 5-15 parts of aluminum-magnesium spinel fine powder, 3-8 parts of aluminum oxide micro powder, 1-5 parts of silicon dioxide micro powder, 3-8 parts of magnesium aluminate gel powder, 2-6 parts of silicon carbide fine powder, 2-6 parts of zirconium oxide fine powder, 1-5 parts of a water reducing agent, 2-3 parts of a plasticizer and 3-5 parts of a preservative. The adhesive has better adhesive property on various refractory bricks for steel ladles; in each temperature stage, good strength and high temperature resistance are achieved, and the corrosion resistance effect on molten steel and steel slag is good; weak links of refractory brick joints are remarkably improved due to small shrinkage, good compactness and better permeation resistance, steel ladle refractory material accidents are reduced, the overall service life of a steel ladle is prolonged, and the safety of the steel ladle is improved.
本发明提供了一种钢包抗侵蚀镁质耐火泥，包括以下重量份数配比的原料：镁砂70‑85份、铝镁尖晶石细粉5‑15份、氧化铝微粉3‑8份、二氧化硅微粉1‑5份、铝酸镁凝胶粉3‑8份、碳化硅细粉2‑6份、氧化锆细粉2‑6份、减水剂1‑5份、增塑剂2‑3份和保存剂3‑5份。该发明对钢包用各种耐火砖有更好的粘结性能；在各个温度阶段具备较好强度和耐高温性能，对熔融钢水与钢渣的侵蚀抵抗效果好；收缩小，致密性好，更好的抗渗透性能显著改善了耐火砖缝的薄弱环节，减少钢包耐材事故，提高钢包整体寿命和安全。
