摘要
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。
Ceramic lined curved pipes of different curvatures and radians can be produced by SHS gravitational separation thermit rotation method,and performing good properties It is found that the pipes with bends have three layer structure of metal intermediate ceramics.Ceramic layers are mainly composed of Al 2O 3 matrix phases assuming dendritic crystals and FeO Al 2O 3 spinel phases and SiO 2 quartz phases distributed at dendritic boundary area Properties of curved pipes similar to those of pipes produced by gravitational separation SHS method and reach present level of ones produced by centrifugal thermit method
