Vacuum Heat Treatment Furnace of Advantages

1) Vacuum heat treatment furnace is heated in vacuum. Vacuum can prevent oxidation and degassing.
A. Anti-oxidation function makes the surface of the workpiece free of decarburization, carburization and removal of phosphorus chips and rust on the surface of the workpiece. The surface of the workpiece is purified, and the solder and catalyst can be better attached to the workpiece surface and the quality of the product can be improved.
B. Degassing. Improve the surface purity and fatigue strength, plasticity and toughness of materials. Thus, the mechanical properties and service life of the workpiece are improved.
(2) High heating temperature can effectively degrease and remove oil contamination, evaporate various impurities and purify the workpiece surface, thus further improving product quality.
(3) The heating rate in the vacuum heat treatment furnace can be controlled, and the temperature deviation in the constant temperature zone is small. It can also be heated slowly, so the temperature of each part of the workpiece is balanced, the temperature difference is small, the thermal stress is small, and the deformation after forming is small. It can easily cooperate with various standard components to ensure the yield and quality of products. The traditional welding process not only can not prevent oxidation, but also the temperature of the welding part is too high, so that the temperature difference between parts of the workpiece is large, and the deformation after forming is huge, which can not meet the requirements of the product.
(4) With the increase of temperature, the solubility of hydrogen will become smaller and smaller, and the hydrogen permeating the workpiece will gradually precipitate, so there is no danger of hydrogen embrittlement in the vacuum heat treatment furnace.
(5) Vacuum heat treatment is controlled by a micro-computer, with low error rate and good process stability and repeatability.
(6) The most important point is that the vacuum heat treatment furnace saves energy and does not need combustible gas. Compared with the controlled atmosphere, it saves raw materials, has low cost and is suitable for large-scale production.
