Corundum magnesium aluminum castable
According to the corundum-magnesium-aluminum castable provided by the invention, the white corundum, the fused magnesite, the active alpha-Al2O3 micro powder, the titanium carbide, the pure calcium aluminate cement, the bentonite, the instant sodium silicate and the modified asphalt are effectively proportioned, so that the high-temperature strength, the expansion rate and other properties of the castable are obviously improved, and when the corundum-magnesium-aluminum castable is applied to a steel ladle castable, the heat loss of a ladle wall can be reduced; and the purposes of prolonging the service life of the steel ladle, reducing the steel cost and cleaning molten steel can be achieved.
本发明提供了一种刚玉镁铝浇注料，通过白刚玉、电熔镁砂、活性α‑Al2O3微粉、碳化钛、纯铝酸钙水泥、膨润土、速溶硅酸钠、改性沥青的有效配比，使得浇注料高温强度、膨胀率等性能提高明显，在钢包浇注料中应用能够降低包壁热量损失，抗剥落性提高，能够实现提高钢包使用寿命、降低钢材成本和洁净钢水的目的。
