Wear-resistant repair material for CFB boiler and preparation method of wear-resistant repair material
The invention discloses a wear-resistant repair material for a CFB boiler and a preparation method of the wear-resistant repair material. The wear-resistant repairing material is prepared from the following components in parts by weight: 45 to 50 parts of brown fused alumina powder, 3 to 5 parts of modified circulating fluidized bed ash, 1.5 to 2 parts of aluminum dihydrogen phosphate cementing agent, 0.8 to 1 part of explosion-proof fiber, 0.6 to 0.9 part of ceramic fiber, 0.2 to 0.5 part of dispersing agent, 2 to 3 parts of zirconium dioxide powder, 2.5 to 4 parts of yttrium oxide powder and 0.8 to 1.5 parts of titanium diboride powder. The preparation method comprises the following steps of: S1, preparing materials; S2, mixing powder; S3, carrying out pulping; and S4, carrying out roasting. The wear-resistant repair material for the CFB boiler has good wear resistance at a high temperature, is suitable for large-area repair and replacement of a dense-phase region of a hearth and the like, can also repair parts with complex structures of a water-cooling air chamber, can adopt an edited smearing repair method, and prolongs the service life of a CFB.
本发明公开了一种CFB循环流化床锅炉用耐磨修补料及其制备方法，所述耐磨修补料以重量份计包括棕刚玉粉末45‑50份、改性循环流化床灰3‑5份、磷酸二氢铝胶结剂1.5‑2份、防爆纤维0.8‑1份、陶瓷纤维0.6‑0.9份、分散剂0.2‑0.5份、二氧化锆粉末2‑3份、氧化钇粉末2.5‑4份、二硼化钛粉末0.8‑1.5份。制备方法包括以下步骤：S1、备料；S2、混粉；S3、制浆；S4、焙烧。本发明的循环流化床锅炉用耐磨修补料在高温下具有良好的耐磨性能，适用于对炉膛密相区等大面积的修补更换，同时也能够对水冷风室结构复杂的部位进行修复，可采取编辑的涂抹修复方法，延长循环流化床的使用寿命。
