【摘要】 传统的工业炉一般采用重质浇注料作为工作衬,存在保温效果较差,能耗高的缺点,本实验研究了在低水泥浇注料中通过添加造孔剂实现基质微孔化技术,高温使用时浇注料基质中原位形成大量分布均匀的微小孔径,降低了浇注料的导热系数,同时有助于浇注料强度的改善。同时优化结合体系和复合微粉进一步优化了浇注料的各项性能,在此基础上开发的高新能轻质高铝浇注料具有较好的常温及高温性能,较低的导热系数、较高的高温强度及体积稳定性,用于1200～1500℃的各种高温窑炉衬体,可达到节能降耗目的,是新一代的优质工业炉炉衬材料。更多还原

【Abstract】 Tradition of industrial furnace using heavy castable as working lining,insulation effect is poorer,the disadvantage of high energy consumption,this experiment studied the low-cement castable in matrix microporous technology was achieved by adding pore-forming agent,when using castable matrix in situ to form a large number of uniform distribution of small aperture,reduce the coefficient of thermal conductivity of castable,help to improve castable strength at the same time.Composite powder at the same time optimization combination system and further optimization of the various properties of castable,can on the basis of the development of high and new lightweight high alumina castable has good normal temperature and high temperature performance,low coefficient of thermal conductivity,high temperature strength and volume stability,for 1200 ～ 1500 ℃ high temperature furnace lining,can achieve saving energy and reducing consumption,is the new generation of high quality industrial furnace lining materials.更多还原
