Steel ladle permanent layer castable
The invention provides a steel ladle permanent layer castable. The steel ladle permanent layer castable is prepared from the following raw materials by weight: 60-70 parts of black aluminum sand aggregate, 15-20 parts of white corundum fine powder, 5-15 parts of alpha aluminum oxide micro powder, 0.5-1.5 parts of fiber, 0.1-0.5 part of silicon micro powder, 5-10 parts of a binding agent, 0.1-1 part of a water reducing agent, 0.01-0.05 part of metal aluminum powder and 0.01-0.05 part of citric acid; wherein the binding agent is one or more of pure calcium aluminate cement, hydrated alumina andsilica-alumina gel powder; the water reducing agent is one or two of sodium tripolyphosphate and sodium hexametaphosphate. The invention has the following beneficial effects that: the ilmenite industrial by-product black aluminum sand is used as the main raw material aggregate, thereby realizing reutilization of the slag, being green and environment-friendly, and lowering the production cost of the castable; by adding the white corundum fine powder and the aluminum oxide micro-powder into the preparation raw materials, the strength and the erosion resistance of the castable product can be improved.
本发明提出了一种钢包永久层浇注料，由下述重量份的原料制成：黑铝砂骨料60～70份，白刚玉细粉15～20份，α氧化铝微粉5～15份，纤维0.5～1.5份，硅微粉0.1～0.5份，结合剂5～10份，减水剂0.1～1份，金属铝粉0.01～0.05份和柠檬酸0.01～0.05份；所述结合剂为纯铝酸钙水泥、水合氧化铝和硅铝凝胶粉中的一种或几种；所述减水剂为三聚磷酸钠和六偏磷酸钠中的一种或两种。本发明的有益效果如下：采用钛铁矿工业副产品黑铝砂作为主原料骨料，实现了渣料的重复再利用，绿色环保，降低浇注料生产成本；通过在制备原料中添加白刚玉细粉和氧化铝微粉，能够提高浇注料产品的强度和抗侵蚀性能。
