采用自蔓延铝热重力分离旋转法制备出曲率与弧度各异、性能良好的陶瓷内衬复合弯管。经研究分析得出，复合弯管具有金属－过渡铁－陶瓷３层结构。陶瓷基体主要由呈枝晶分布的Ａｌ２Ｏ３基体相和分布其间的ＦｅＯ．Ａｌ２Ｏ３尖晶石相、石英相所组成。复合弯管的性能与重力分离ＳＨＳ复合直管的性能相近，基本达到了离心ＳＨＳ复合钢管的相应水平。
The self-propagating aluminum thermogravimetric separation rotary method is used to prepare ceramic-lined composite elbows with different curvature and radian and good performance. After research and analysis, the composite pipe has a metal - transitional iron - ceramic 3-layer structure. The ceramic matrix mainly consists of a matrix of Al2O3 matrix dendrites distributed and FeO distributed therebetween. Al2O3 spinel phase, composed of quartz phase. The performance of composite pipe bending and gravity separation SHS composite straight pipe performance similar to the basic level reached the corresponding level of centrifugal SHS composite pipe.
