文档介绍：摘要本文为了测定高铝质陶瓷蓄热材料的抗热震性能、常温抗压强度等性能,通过比较蓄热材料中各种矿物组成的性质差异,选择了莫来石、氧化铝和二氧化硅为骨料的配方,制作成蓄热陶瓷小球。经过适当的成型和烧结工艺,研制开发了高铝质陶瓷球蓄热体。用水骤冷实验法测试不同配方制作的陶瓷球在高温下的抗热震性能,以及用液压机测定小球的抗压强度。初步讨论其损坏机理。通过实验得出以下结论:以莫来石、氧化铝和二氧化硅为骨料制作的陶瓷球蓄热体的抗热震性能非常好,急冷急热次数达到 30 次以上;该配方样品的抗压强度适中,能够符合工作的要求。该种以莫来石、氧化铝和二氧化硅为骨料配方的陶瓷蓄热体是很好的也是比较理想的蓄热体。关键词:蓄热材料陶瓷球莫来石抗热震性抗压强度 Abstract Based onthe rolling mill regenerative furnace production practice, paring various storage materials position differences inthe nature and chose mullite, alumina and silica formulation ofthe aggregate production ofceramic regenerator into small balls. After the forming and sintering technology, wedeveloped ahigh alumina ceramic ball regenerator. Sudden cold water experiment testing different formula produced bythe high temperature ceramic ball inthe thermal shock resistance. and the use ofhydraulic pressive strength ofthe small ball. Discuss its preliminary damage mechanism. Through e tothe following conclusions :mullite, alumina and silica for the aggregate production ofceramic ball regenerator of thermal shock resistance isvery good. Heat cooled rapidly reach s30 above; The samples moderate strength tomeet the job requirements. Formulation ofthe kinds ofceramic regenerator isavery parison isthe ideal regenerator. Key words :storage materials ceramic ball mullite thermal shock resistance strength 目录一、文献综述................................................................................................................ 4 绪论......................................................................................................................................... 5 1、蓄热技术的发展.................................................................................................... 5 国内蓄热式燃烧技术情况........................................................................ 6 蓄热燃烧技术和蓄热材料........................................................................ 7 蓄热体材质的选择....................................................................................... 8
