Corundum self-flowing castable based on circulating refractory material and preparation method thereof
The invention relates to a corundum self-flowing castable based on a circulating refractory material and a preparation method of the corundum self-flowing castable. According to the technical scheme, the preparation method comprises the following steps: firstly, taking 35.0 to 47.0 weight percent of circulating corundum aggregate, 25.0 to 34.0 weight percent of circulating high-voltage electric porcelain aggregate, 13.0 to 19.0 weight percent of defective spinel fine powder, 6.0 to 9.0 weight percent of active alpha aluminum oxide, 2.0 to 5.0 weight percent of brown aluminum oxide dust removal powder and 1.5 to 4.5 weight percent of hydratable aluminum oxide as raw materials, adding 4.5 to 6.5 weight percent of water, 3.5 to 4.5 weight percent of retarder, 1.5 to 2.5 weight percent of stabilizer and 0.05 to 0.08 weight percent of circulating basalt fiber, and uniformly mixing; the corundum self-flowing castable based on the circulating refractory material is obtained. Therefore, the method has the characteristics of energy conservation, high efficiency, environment friendliness and low cost; the prepared corundum self-flowing castable based on the circulating refractory material is excellent in thermal shock resistance, high in mechanical strength and relatively high in use temperature.
本发明涉及一种基于循环耐火材料的刚玉自流浇注料及其制备方法。其技术方案是：先以35.0~47.0wt%的循环刚玉骨料和25.0~34.0wt%的循环高压电瓷骨料，13.0~19.0wt%的缺陷尖晶石细粉，6.0~9.0wt%的活性α氧化铝，2.0~5.0wt%的棕刚玉除尘粉，1.5~4.5wt%的可水合氧化铝为原料，再外加4.5~6.5wt%的水、3.5~4.5wt%的缓凝剂、1.5~2.5wt%的稳定剂和0.05~0.08wt%的循环玄武岩纤维，混合均匀，即得基于循环耐火材料的刚玉自流浇注料。因此，本发明具有节能高效、绿色环保和成本低廉的特点；所制备的基于循环耐火材料的刚玉自流浇注料热震稳定性优良、机械强度高、使用温度较高。
