Alumina-based cordierite explosion-proof castable
The invention relates to the field of heat-resistant materials, in particular to an alumina-based cordierite explosion-proof castable which comprises the following components in parts by weight: 60-80 parts of high bauxite clinker, 30-50 parts of cordierite, 10-20 parts of silicon dioxide micropowder, 3-5 parts of aluminate cement, 15-30 parts of alumina powder, 5-10 parts of silicon elementary substance micropowder and 1-5 parts of modified carbon fibers. The modified carbon fibers are coated with an inorganic silicon dioxide coating layer. The alumina-based cordierite explosion-proof castable disclosed by the invention not only has good high temperature resistance, but also has good thermal shock resistance, and is suitable for lining parts with excellent stripping resistance and wear resistance and occasions with requirements on thermal shock.
本发明涉及耐热材料领域，尤其涉及一种矾土基堇青石防爆浇注料，按照重量份数计，包括高铝矾土熟料60~80份、堇青石30~50份、二氧化硅微粉10~20份、铝酸盐水泥3~5份、氧化铝粉15~30份、硅单质微粉5~10份、改性碳纤维1~5份；其中，所述改性碳纤维在其外部包覆有一层无机二氧化硅包覆层。本发明中的矾土基堇青石防爆浇注料不仅具有良好的耐高温性能，而且还有很好的抗热震性能，适用于耐剥落及耐磨性优良的衬里部位和对热震性有要求的场合。
