Lining castable for integral casting of blast furnace belly pipe
The invention discloses a lining castable for integral casting of a blast furnace belly pipe. The castable comprises the following components in parts by weight: 10-12 parts of liquid silica sol, 2-5 parts of calcium aluminate cement, 50-60 parts of mullite with aluminum content of 70, 10-20 parts of brown aluminum oxide, 7-20 parts of silicon carbide, 6-12 parts of alpha activated aluminum oxide micro powder and 3-8 parts of silicon oxide micro powder. The castable overcomes the preparation problems that an existing belly pipe castable needs to be maintained for a long time after pouring is completed and needs to be baked according to a strict baking system at the temperature of 450 DEG C or above, has high wear resistance and good thermal shock resistance stability, and can effectively resist erosion of slag iron to refractory materials during slag pouring of a blast furnace tuyere.
本发明公开了一种用于高炉直吹管整体浇注的内衬浇注料，本浇注料包括以下重量份的组分：液态硅溶胶10～12份、铝酸钙水泥2～5份、铝含量为70的莫来石50～60份、棕刚玉10～20份、碳化硅7～20份、α活性氧化铝微粉6～12份、氧化硅微粉3～8份。本浇注料克服现用直吹管浇注料在浇注完成后需长时间养护，并需在450℃以上按照严格烘烤制度进行烘烤的制备难题，具有高耐磨和良好抗热震稳定性能，能有效抵抗高炉风口灌渣时渣铁对耐材的侵蚀。
