摘要
在540℃和565℃下进行了30Cr1Mo1V钢的蠕变试验。用θ函数法对蠕变试验数据进行了处理,给出了这两种温度下的持久强度公式,并将试验结果与文献[1]中30Cr1Mo1V和30Cr2MoV转子钢在相应温度下的持久强度曲线进行了比较。试验结果表明,虽然565℃时30Cr1Mo1V钢的持久强度比540℃时有较大幅度的下降,但仍然比30Cr2MoV转子钢在538℃下的持久强度高。因此,就持久强度方面而言,将30Cr1Mo1V转子钢的使用温度提高到565℃是可行的。
The creep experiments were performed at 540 ℃ and 565 ℃ for 30Cr1Mo1V steel. The experimental data were processed with θ project functron. The formulas of lasting-strength are presented at the two temperatures, and the experiment results are compared with that of 30Cr1Mo1V and 30Cr2MoV reported in Ref [1]. The results show that the lasting-strength of 30Cr1Mo1V at 565 ℃ in decreased greatly comparing with that at 540 ℃, but is still higher than that of 30Cr2MoV at 540 ℃. Thus 30Cr1Mo1V can be used for turbine rotor at 565 ℃ from the view of creep strength.
