Abstract Quenching distortion of bearing rings seriously affects their dimensional accuracy and service performance in industrial production. To address this issue, this study proposes a distortion control method for bearing rings during quenching in widely used mesh-belt furnaces, focusing on the effect of motor frequency on the flipping state of bearing rings.

In international finance, intermarket connectedness and dependence are crucial factors that provide valuable insights for fund managers and policymakers. However, with the increasing reliance on fossil-fuel based economies, the emission of climate risks has become a significant concern in recent years. To promote sustainability, the adoption of clean energy has emerged as a promising approach to combat the climate risks associated with conventional energy systems (Chen et al., 2022a).

Abstract During the thermal simulation compression test, the formation of an obvious bulge in the specimen leads to a certain deviation between the calculated and actual values of the true stress. The finite element method was used to simulate the single-pass compression of specimens of 34CrNi3MoV steel and obtain the actual nonuniform deformation of the bulging belly during the compression process, and the results were applied to correct experimental flow curves.
