Castable for ladle slagging-off plate, ladle slagging-off plate and preparation method thereof
The invention provides a castable for a ladle slagging-off plate, the ladle slagging-off plate and a preparation method thereof. The castable for the ladle slagging-off plate comprises the following components in parts by mass: 50-70 parts of Al2O3-SiC-C mixed waste, 10-20 parts of kyanite tailings, 2-4 parts of aluminum oxide, 0.1-0.2 part of explosion-proof fiber, 3-6 parts of calcium aluminate cement and 0.25-0.8 part of an additive. The Al2O3-SiC-C mixed waste and the kyanite tailings are used as main raw materials, and the waste contains a large amount of SiC and C so that the wettability of molten iron, slag, a desulfurizing agent and the surface of a castable matrix can be effectively reduced, the slagging-off efficiency is improved, and the quality of the molten iron is optimized. In addition, the slag and the molten iron are not easy to adhere to the surface of the matrix, so that the erosion resistance of the castable is improved, the smoothness of the surface of the castable is ensured, and the adhesion of the slag in the molten iron is reduced. Secondly, industrial waste Al2O3-SiC-C waste and kyanite tailings are effectively recycled, resources are saved, and the castable is suitable for industrial production.
本发明提供了一种用于铁水包扒渣板的浇注料、铁水包扒渣板及其制备方法，用于铁水包扒渣板的浇注料包括以下组分按质量份数：50～70份Al2O3‑SiC‑C混合废料，10～20份蓝晶石尾矿，2～4份氧化铝，0.1～0.2份防爆纤维，3～6份铝酸钙水泥以及0.25～0.8份添加剂。本发明采用Al2O3‑SiC‑C混合废料以及蓝晶石尾矿作为主要原料，废料中含有大量的SiC和C能有效降低铁水、渣质以及脱硫剂与浇注料基质表面的浸润性、提高了扒渣效率并优化铁水品质。此外，由于渣质及铁水不易粘附于基体表面进而提升了浇注料的抗侵蚀性能并保证浇注料表面的光滑减少铁水中渣质的粘附。第二，有效地将工业废弃物Al2O3‑SiC‑C废料以及蓝晶石尾矿回收利用，节约资源、适合工业化生产。
