近来,随着真空油淬达到控制变形的发展,首要任务是研制一种控制装置来确保零件获得重复一致的结果。本文讨论了在二台试验炉及生产设备上应用测量装置和控制装置的情况。钢件淬火是否能完全转变,不仅取决于该钢本身的淬透性,而且取决于淬火介质的冷却能力。零件过快的冷却或不均匀的冷却,可能会使零件产生过大的变形与开裂。要避免这些问题,零件直在有关的等温转变曲线的“鼻子”区域快冷,逃过“鼻子”后,以尽可能
Recently, with vacuum oil quenching to control the development of deformation, the first task is to develop a control device to ensure that parts get consistent results. This article discusses the application of measuring and control equipment to two test furnaces and production equipment. Whether the quenching of the steel can completely change depends not only on the hardenability of the steel itself but also on the cooling capacity of the quenching medium. Excessive cooling or uneven cooling of the part may cause excessive deformation and cracking of the part. To avoid these problems, the part straightens quickly in the “nose” region of the associated isothermal transition curve and escapes as much as possible after “nose”
