The different influences in the different quenching temperatures of a fixed carbon potential is that, the hardness of oil quench in 0.7% carbon potential is rising with temperature, there is obvious secondary hardening in 0.7% carbon poential. 在不同淬火温度同一碳势的回火硬度的曲线中,0.70/0碳势下油淬的硬度随淬火温度升高而增加,有明显的二次硬化现象。
The mechanical properties of oil hardening and tempering spring wire were introducer in this paper, The process and system constitutes for spring wire with induction heating were proposed, The operation principle of this system was also discussed. 介绍了油回火弹簧钢丝的力学性能,给出了油回火弹簧钢丝感应加热生产工艺流程及系统组成,简述了系统各部分的技术功能及特点。
Based on the basic mechanical theory and practice, and on the needs in the performance of petroleum mechanical products used in oil recovery, we raise a method to cool the long metal tube evenly after the hardening and tempering. 根据石油开采业对石油机械产品的需求,利用机械理论基础知识,通过实践设计,提出了对几何尺寸长的金属管类进行调质处理后的均匀冷却方法,以满足其性能要求。
A method for determining oil and water saturations in cores by volume?_CT scanner was developed on the basis of X_ray hardening treatment, X_ray drifting correction, martix transformation of imagines and position correction of CT images with volume? 对CT图像进行了X射线硬化处理、X射线漂移校正、图像矩阵变换及体积CT位置校正,研究出用体积CT对岩心流体饱和度进行测量的技术。
The network YAG laser hardening on the surface of cylinder forms numerous micro oil pools with hardening skeleton constructed by laser quenching, which are favourable to the lubrication between cylinder and piston ring. 结果表明,采用YAG激光网纹状淬火可在汽缸表面形成众多的、以激光淬火形成骨架的微油池,它有利于活塞环与汽缸间的润滑。
By measuring the cooling curve and quench severity of quenching oil at various flow rates, the relationship among the hardening capacity, quench severity and flow rate was established. 对淬火油在不同流速下的冷却曲线和淬火烈度进行了测量,建立了硬化能力、淬火烈度与介质流速三者之间的关系。
