Description

一种循环流化床锅炉炉顶耐磨浇注料及其制备方法
技术领域
本发明属于循环流化床锅炉耐磨浇注料技术领域。具体涉及一种循环流化床锅炉炉顶耐磨浇注料及其制备方法。
背景技术
循环流化床锅炉是一种高效低耗的热能利用技术，但在运行过程中，受燃料、助燃剂和脱硫剂等添加剂的影响，尤其是循环流化床锅炉炉顶长期遭受烟气和尘粒的冲刷与磨损，烟尘中的细小颗粒在高温下易与炉顶耐火材料发生反应形成低熔相，进而对炉顶造成侵蚀与渗透，这对循环流化床锅炉炉顶耐火材料提出了严格的要求。
“一种陶瓷结合高强耐磨浇注料的制备方法CN201110302742.6”专利技术，以电熔莫来石、红柱石和板状刚玉颗粒等为主要原料，以纯铝酸盐水泥和二氧化硅微粉为结合剂，再外加长石族矿物细粉和耐热不锈钢纤维等组分，经搅拌、浇注后养护，制得陶瓷结合高强耐磨浇注料。该技术所制备的复合材料具有高强度和良好的耐磨性，对使用环境的温度适应性较强，但其主要缺点在于原料组分复杂，制备工艺要求高，且纯铝酸盐水泥结合在高温下易产生低熔相，降低材料的抗侵蚀性能；此外，电熔莫来石、板状刚玉等耐火原料成本较高，增大了耐磨浇注料的开发成本。

为实现上述目的，本发明所采用的技术方案是：以20～25wt％的钛铁渣颗粒和40～45wt％的烧结莫来石颗粒为骨料，以20～25wt％的烧结莫来石细粉、7～12wt％的γ-氧化铝微粉、1～4wt％的锆英石细粉和1～4wt％的二硼化锆微粉为基质料；先将所述基质料混匀，再将混匀后的基质料加入所述骨料中，混合均匀，即得混合料；然后向所述混合料中依次加入占所述混合料8～10wt％的铝溶胶和0.05～0.1wt％的聚丙烯酸钠，搅拌均匀，振动成型，室温条件下养护12～24小时，在90～110℃条件下保温12～24h，制得循环流化床锅炉炉顶耐磨浇注料。
所述钛铁渣颗粒为冶炼钛铁合金所产生的炉渣，钛铁渣颗粒的主要化学成分是：Al2O3含量为75～80wt％，TiO2含量为8～10wt％，CaO含量为5～8wt％，Fe2O3含量≤1wt％；所述钛铁渣颗粒的粒度为0.1～6mm。
