摘要/Abstract

摘要：

针对矫直工艺参数和特殊热处理对蒸汽发生器690合金传热管拉伸性能的影响进行了研究.结果表明: 在矫直后690合金传热管室温屈服强度增大,而抗拉强度变化不大; 校直压力对管材屈服强度的影响较大,校直压力对校直速度的影响较小; 矫直压力越大,管材室温屈服强度的增量越大.根据测试结果可对批量矫直后的管材性能进行预测,并验证该矫直工艺具有较好的工艺稳定性.

关键词: 690合金传热管, 矫直工艺, 室温拉伸性能, 特殊热处理

Abstract:

Influences of straightening process and thermal treatment on the tension properties of 690 alloy tube used in steam generators were investigated. The following influence rules have been revealed. Straightening can significantly increase the room temperature yield strength of the tube, but has little effect on tensile strength. Straightening pressure has a great influence on yield strength, while straightening speed has less impact. A higher straightening pressure makes a larger increment of yield strength. Tension property of the tube after straightening can be predicted according to the test results. The process of straightening has been shown to be stable.

Key words: 690 alloy heat exchange tube, straightening process, room temperature tension property, thermal treatment
