Description

焦化炉门用耐火可塑料
技术领域
本发明涉及焦化炉门用耐火可塑料，属于耐火技术领域。
背景技术
焦化炉门在改造前一般是使用莫来石砖砌筑的，由于莫来石砖的强度不够好，通常60个压力左右，加上砖与砖之间的结合不好，在长期运行的过程中有碰撞，同时也要经受高温1350℃、低温-35℃的频繁考验，很容易产生砖与砖之间的脱落和开裂，所以要在生产时不断的更换和修复。
发明内容
为了解决目前存在的问题，本发明提供了焦化炉门用耐火可塑料，本发明焦化炉门用耐火可塑料相比于以往的莫来石砖，强度更高，耐磨性更好，。本发明提高了锅炉的修补水平，延长了保修期，提高了运行质量和经济效益。
具体技术方案为：
焦化炉门用耐火可塑料，包括粘结剂和主料；所述的粘结剂为磷酸二氢铝，所述的主料包括骨料、填料、金属氧化物和烧结助剂；所述的骨料为刚玉，所述的填料为氧化铝为主的无机耐火填料。
所述粘结剂为浓度1.35-1.70g/mL磷酸二氢铝水溶液；所述的主料与粘结剂的用量，按照重量比为100:15-25。
所述金属氧化物为氧化镁、氧化锌、氧化铜、氧化锆、氧化钙中的任意一种或者多种混合。
所述烧结助剂为氧化镍、铝酸钠中的任意一种或者多种。
所述骨料用量占主料质量的42％-65％，填料的用量占主料质量的25％-35％。
所述骨料的粒径不大于3mm。
与现有技术相比有以下优点：
用不定型的可塑料来代替原来的定型莫来石砖，增加炉门的整体性提高炉门的强度。该耐火可塑料，致密度高，具有优异的耐磨性。施工方便，使用时只需将主料和粘结剂按照比例进行混合搅拌均匀，涂抹在需要修补的炉门部位后压实，室温下固化干燥后即可。
