Advantages and characteristics of vacuum heat treatment furnace

Vacuum heat treatment skill is the comprehensive skill of vacuum skill and heat treatment skill, which is carried out in vacuum. In China, vacuum is divided into four types: low, medium, high and ultra-high vacuum. At present, the vacuum degree of most vacuum heat treatment medium frequency furnaces is 1.33 ~ 1.33 × 10-3pa.

Vacuum heat treatment can almost complete all heat treatment processes, such as quenching, annealing, tempering, carburizing and nitriding. In the quenching process, it can complete gas quenching, oil quenching, nitrate quenching, water quenching, etc., as well as vacuum brazing, sintering, surface treatment, etc. The vacuum heat treatment furnace has high thermal efficiency, can complete rapid leveling and cooling, can complete no oxidation, no decarburization, no carburization, can remove the phosphorus chips on the surface of the workpiece, and has the effect of degreasing and degassing, and then achieve the result of surface bright purification.

Generally speaking, the workpiece is heated slowly in the vacuum induction furnace, the internal temperature difference is small, the thermal stress is small, so the deformation is small. The qualified rate of product is high. It can reduce the cost, has degassing effect, and then improves the mechanical function and service life of the task. The task is in good condition, the operation is safe, and there is no pollution and public hazard. There is no risk of hydrogen embrittlement for the disposed workpiece, and hydrogen embrittlement is avoided for titanium and refractory metal shell. The invariability and repeatability of vacuum heat treatment process are good. This series of advantages, vacuum heat treatment equipment and technology are more and more attention and use more and more widely.
