Improvement of carburizing and quenching process for  20Cr2Ni4A steel steering gear

doi:10.13251/j.issn.0254-6051.2024.08.033

Abstract

Abstract: Aiming at the problem of excessive plane warping of 20Cr2Ni4A steering gears after carburizing and quenching, the optimization of the pressure quenching process was guided by finite element simulation carburizing and quenching simulation, and experimental verification was carried out. The results show that the loading method, machining allowance, and quenching pressure have a significant impact on the stress and distortion fields during the carburization and quenching process of the steering gear. The distortion is smaller when using hanging loading than flat loading. Increasing the thickness of the web plate can reduce the distortion. When the web plate thickens to 18 mm, the ellipticity after carburization can be controlled to 0.19 mm. When the outer ring pressure of pressure quenching is 3 MPa, the ellipticity after quenching can be controlled to 0.16 mm.
