安钢3^(#)高炉调压阀组减振改造

OPTIMIZATION PRACTICE OF PRESSURE REGULATING VALVE GROUP IN ANGANG 3^(#) BLAST FURNACE

以安钢3^(#)高炉调压阀组为研究对象,分析了调压阀组振动破坏的原因,总结其存在的问题。通过对振动方程分析提出改变管线系统的振动特性的措施,可以通过提高刚质比、增加阻尼、增加系统的刚度、减小激振力等来减小振动。生产实际证明改造具有良好效果,保障了高炉的正常生产。

Taking the pressure regulating valve group of Angang 3^(#) blast furnace as the research object, the reasons for the vibration damage of the pressure regulating valve group are analyzed, and the existing problems are summarized. Through the analysis of the vibration equation, measures to change the vibration characteristics of the pipeline system are proposed.The vibration can be reduced by increasing the rigidity-to-mass ratio, increasing the damping, increasing the stiffness of the system, and reducing the exciting force. The results show that the transformation has a good effect and ensures the normal production of the blast furnace.
