摘　　要：在介绍重力分离SHS高温合成陶瓷内衬复合钢管制备原理的基础上,通过有限元模拟计算了细长复合管冷却过程中的温度分布。分析了冷却速度、钢管壁厚和预热温度对残余应力的影响,提出了有效改善复合管性能的措施。On the basis of introducing the manufacture principles of gravitational separation SHS ceramic-lined composite slender pipe, the temperature distribution of the ceramic-lined composite slender pipe during cooling process was analyzed by finite element simulation calculation. The influences of cooling rate, wall thickness of steel pipe and preheating temperature on the residual stress were analyzed. The measures for improving the properties of the composite pipe were put forward.
