柔性伸缩节用以解决高温作业的各种设备及管道热膨胀的问题。随着大型冶金设备的发展、设备与管道、管道与管道之间,广泛使用伸缩节,并逐渐向大型化方向发展。现以宝钢450m~2烧结机为例,对大型柔性伸缩节的结构及消化移植等问题作一介绍。 1.大型柔性伸缩节的特点 1)能调节热膨胀过程中复杂的变位要求,可调节任何方向的热膨胀位移; 2)耐热性能好,由于伸缩节主要采用石棉与不锈钢丝交织的织物,可在介质温度250℃～500℃的条件下使用; 3)体积小重量轻;
Flexible telescopic section to solve the high temperature operation of various equipment and piping thermal expansion problems. With the development of large-scale metallurgical equipment, extensive use of expansion joints between equipment and pipelines, pipelines and pipelines, and gradually to large-scale development. Taking Baosteel 450m ~ 2 sintering machine as an example, the structure and digestion and transplantation of large flexible expansion joint are introduced. 1. Features of large flexible telescopic section 1) Can regulate the complex displacement requirements in thermal expansion process, can adjust the thermal expansion displacement in any direction; 2) The heat-resistant performance is good, because the telescopic section mainly adopts the fabric interwoven with asbestos and stainless steel wire, The medium temperature 250 ℃ ~ 500 ℃ under the conditions of use; 3) small size and light weight;
