Comprehensive technology of vacuum heat treatment vacuum technology and heat treatment technology of two professional combination, refers to the heat treatment process of all or part of the vacuum condition. Is generally believed that the vacuum furnace is divided into high, high, medium and low vacuum.
Vacuum heat treatment technology can almost all heat treatment, such as annealing, quenching, tempering, carburizing, nitriding, the quenching process can realize gas quenching, oil quenching, nitrate quenching, quenching and so on, can also be used for vacuum brazing, sintering and surface treatment etc.. Vacuum heat treatment furnace heat efficiency is high, can achieve rapid heating and cooling, can realize no oxidation, no decarburization, no carburizing, can remove phosphorus removal the surface of workpiece, and skim degassing effect, so as to achieve the effect of purifying the surface bright. In general, the workpiece is the slow heating in the furnace, heat temperature difference is small, small thermal stress, so the small deformation. The high rate of qualified products. The cost can be reduced, a degassing effect, thus improving the mechanical properties and service life of work. The working environment is good, safe operation, no pollution and public nuisance. The workpiece is processed without the risk of hydrogen embrittlement of titanium material, and refractory metal shell surface to prevent hydrogen embrittlement, vacuum heat treatment process stability and good repeatability. The advantages of this series, the development of vacuum heat treatment equipment and technology has been paid more and more attention and applied more and more widely.
