Description

[0001] Technical field: [0002] The invention belongs to the technical field of quenching and cooling, and relates to a quenching and cooling device, in particular to an automatic cooling device for a continuous roller hearth furnace quenching production line. [0003] Background technique: [0004] Quenching is a heat treatment process that heats a metal workpiece to the austenitizing temperature and holds it for a certain period of time, and then cools it at a rate greater than the critical cooling rate to obtain a non-diffused transformation structure, such as martensite, bainite or austenite. Quenching cooling is the process of rapid cooling of the heated workpiece, which is crucial to the transformation of the structure and the acquisition of the desired properties. In order to realize the quenching and cooling of metal workpieces, achieve the required structure and properties, and at the same time avoid cracking and deformation of the workpieces during the cooling proces...
