| 摘 要： | 通过对汽缸结合面高温螺栓的性能试验分析,认为预紧力过大和预紧力不均匀是影响高温螺栓安全使用性能的主要因素。对此,提出了限制运行周期和紧固次数,加强对螺栓超声波探伤和表面探伤等防止高温螺栓失效的具体措施。

| Abstract: | Through analysis of performance test for high temperature bolts on joint face of the steam cylinder,it is believed that the main factors affecting the safe application performance of high temperature bolts are undue and nonhomogeneous pretightening loads.For this reason,limiting the operation period and the tightening times has been put forward,and concrete measures for preventing failure of high temperature bolts,such as ultrasonic detection and surface inspection etc.,being strengthened. |
