High-strength wear-resistant castable and preparation method thereof
According to the high-strength wear-resistant castable and the preparation method thereof, a high-aluminum casting material is used as a main material, magnesia is added to form a magnesia casting material, and the high-strength wear-resistant castable has the characteristics of light weight, high temperature resistance, wear resistance, thermal stability and good thermal insulation performance. And meanwhile, the magnesium casting material can absorb Al2O3 inclusions in molten steel and slag to form magnesium aluminate spinel on the surface of the magnesium casting material, has good corrosion resistance to alkaline slag and iron slag, and also has an effect of purifying the molten steel. And the water discharge amount can be reduced, and the cracking possibility of the magnesium material in the baking process is reduced. And meanwhile, the MgO particles are mutually connected by magnesium oxide silicon chains, so that the strength of the casting material is improved. The density of the castable is reduced by utilizing the complex-phase hollow spheres, the sintering of aluminum oxide at high temperature is promoted by utilizing the catalytic action of titanium oxide, the combination of all components in the castable is promoted, the density is reduced and the strength is improved on the whole, and the hollow spheres also provide an embedding effect, so that the combination effect of other materials and the castable is further improved.
本发明公开了一种高强耐磨浇注料及其制备方法，以高铝质浇注材料为主，增加镁砂，形成镁质浇注材料，在具备重量轻、耐高温、抗磨性、热稳定性和保温性能好的特点。同时镁质浇注材料能够吸收熔融钢水和渣中Al2O3夹杂物在其表面形成镁铝尖晶石，对碱性渣和铁渣都有很好的抗侵蚀性，同时也具有净化钢水的作用。还可以减少排水量，降低了镁质材料烘烤过程中开裂的可能性。同时由于MgO颗粒被镁氧硅链互相连接起来，从而提高了浇筑料的强度。利用复相空心球，减少浇注料的密度，并且利用氧化钛的催化作用，促进氧化铝在高温下的烧结，促进浇注料中各组分的结合，整体上降低密度提高强度，并且空心球还提供嵌合作用，进一步提升其他物料与其的结合效果。
