Abstract: This paper analyzes the various influencing factors of gear heat treatment deformation, and points out that the heat treatment deformation of gear parts is mainly affected by many factors
Applications: In the workpiece subjected to alternating loads such as torsion and bending, the surface layer is required to withstand higher stress or wear resistance than the core, and
In a unified way Φ 50 4140 mm x 300 mm steel bending fatigue test specimens. The samples were austenitized at 860℃ in a protective atmosphere, and then conventional quenching
For the quenching of a single workpiece, the spray quenching technology itself can achieve controllable pre-cooling quenching, because it can be preset for the beginning of the spray. For batch
In order to achieve reverse quenching, steel with appropriate hardenability, a workpiece with sufficient cross-section, suitable cooling medium, and correct cooling conditions are required. If these conditions are met, this
Metal reverse quenching is a quenching method that the hardness of the core is higher than that of the surface by pre-cooling quenching and making the quenching cooling process discontinuous.
1. Hardening crack Hardening crack is the most common defect of high frequency induction hardening. There are many causes, such as overheat, too fast cooling speed, and improper microstructure before
Heat treatment is the weight of the decision to high-quality products. The process method should be optimized and the equipment performance should be mastered. Correct parameter selection for each paragraph,
