Low-carbon corundum spinel impact brick for tundish and preparation method thereof
The invention provides a low-carbon corundum spinel impact brick for a tundish and a preparation method of the low-carbon corundum spinel impact brick. The low-carbon corundum spinel impact brick for the tundish comprises the low-carbon corundum spinel impact brick, and the low-carbon corundum spinel impact brick is formed by processing the following raw materials: low-carbon corundum aggregate, aluminum-rich spinel, fused magnesite powder, SiO2 micro powder, special cement and an anti-explosion agent. The low-carbon corundum spinel impact brick for the tundish and the preparation method of the low-carbon corundum spinel impact brick have the advantages that the low-carbon corundum spinel impact brick for the tundish is small in thermal expansion rate, good in thermal stripping resistance, high in high-temperature strength, good in slag and molten steel corrosion resistance and permeability, capable of being blended, capable of being used in the tundish, the tundish wall and the slag line part respectively, stable in structure, small in stripping depth and low in stripping speed.
本发明提供一种中包用低碳刚玉尖晶石冲击砖及其制备方法。所述中包用低碳刚玉尖晶石冲击砖包括：低碳刚玉尖晶石冲击砖，所述低碳刚玉尖晶石冲击砖由是由以原料加工而成：低碳刚玉骨料、富铝尖晶石、电熔镁砂粉、SiO2微粉、专用水泥和防爆剂。本发明提供的中包用低碳刚玉尖晶石冲击砖及其制备方法具有热膨胀率小、抗热剥落性好、高温强度高以及良好的抗渣和钢水的侵蚀性及渗透性，且可调配，可分别用在包中、包壁及渣线部位，结构稳定，剥落深度小和剥落速度慢的优点。
