摘　　要：对静态铸造的含静态混合元件的乙烯炉管,进行了高温机械性能和微观组织的评价,对其材料的化学成分、高温短时拉伸性能和微观金相组织与寿命消耗分散程度等方面进行了与常规炉管的对比分析.结果表明,由于静态混合元件的使用明显降低了炉管表面温度,所以其服役寿命满足要求.Assessment of hightemperature mechanical properties and microstructure of ethylene cracking furnace tube with static mixer units statically casted is presented here. Its chemical composition ,shorttime tensile properties at high temperature, microscopic metallographic structure, and deterioration of service life are compared to those of conventional furnace tubes. The investigation result shows that the surface temperature of tubes is remarkably reduced due to the static mixed units so that their service life meets the requirement.
