    X80鋼級厚壁彎管組織及性能梯度的研究分析

    Analysis on Microstructure and Property Gradient of X80 Heavy-wall Elbow

    • 摘要: 簡要介紹了彎管生產(chǎn)過程中的中頻淬火煨制工藝的特點(diǎn)，重點(diǎn)針對電流透入深度做了分析，指出中頻淬火的工藝特點(diǎn)決定了厚壁彎管在煨制時(shí)，必然在其內(nèi)外表面存在著不同的加熱溫度與冷卻速度，從而導(dǎo)致彎管組織和性能上的差異。通過一系列的試驗(yàn)證明：X80鋼級厚壁彎管壁厚的內(nèi)、中、外各處均表現(xiàn)出不同的組織特點(diǎn)，從而在最終熱處理后存在著性能的差異。對煨制彎管工藝的未來發(fā)展提出了見解。

       

      Abstract: Briefed in the essay are the characteristics of mid-frequency quench bending process as employed for manufacturing steel elbow, focusing on an analysis on current penetration depth.It is pointed out that during hot-bending of the heavy-wall elbow, the characteristics of the mid-frequency quenching process as used shall eventually cause the differences between heating temperatures on and cooling velocities of the outer and inner surfaces, and accordingly bring about the differences of microstructures and properties of the elbow.A serial of tests demonstrate that different microstructure characteristics show separately in the inner, middle and outer areas of the X80 heavy-wall elbow wall, which determine the property differences of the material after being finally heat treated.Moreover relevant opinions about the future development of the elbow hot-bending process is put forward.
