Description

Technical Field

[0001] The present invention relates to the field of heat treatment technology, and in particular to a digital intelligent heat treatment equipment. Background Art

[0002] Heat treatment equipment is a device that changes the internal structure of materials through processes such as heating, insulation and cooling, thereby improving their physical, chemical and mechanical properties. By using heat treatment equipment to perform quenching heat treatment on metal parts such as automotive gears and robot joints, metal parts such as automotive gears and robot joints gain higher hardness and wear resistance.

[0003] In the prior art, when heat treating metal parts, the metal parts heated to the austenitizing temperature are immersed in water for quenching. Since the cooling water lacks the ability to dynamically adjust the temperature field, the initial temperature of the medium is usually low and relatively constant, resulting in excessive cooling intensity in the initial stage of quenching. This intense heat conduction process will form a steep temperature gradient of more than 200°C / s between the surface and the core of the workpiece, inducing thermal stress and structural stress. The composite stress peak of the two exceeds the dynamic yield strength of the material, which will trigger the release of elastic strain energy and cause partial metal deformation, resulting in transgranular cracks in the stress concentration area, which seriously restricts the qualified rate of metal parts.
