The vacuum heat treatment furnace in the automobile exhaust purifier manufacture concrete action

As the carrier of automobile exhaust purifier consists of casing, liner, and the catalyst components. We want to make them together and have the purpose of purifying exhaust, which would involve the components between the joint and the joint between catalyst and components. Vacuum heat treatment furnace is the use of its advantages, the success of the parts will fit together.
The vacuum heat treatment furnace in the automobile exhaust purifier manufacture concrete action
(1) the vacuum heat treatment furnace heating in vacuum, vacuum to prevent oxidation, degassing effect.
A, anti-oxidation function make the workpiece surface decarburization, carburizing, also can remove phosphorus chip and rust on the surface of the workpiece. Cleaning the surface, can make the solder and catalyst better adhere to the surface, improve the quality of the products.
B, degassing effect. Improve the purity of material surface, improve the fatigue strength, plasticity and toughness. So as to improve the mechanical properties of the workpiece and service life.
(2) the high heating temperature, skim and effectively remove oil, the evaporation of various impurities, purify surface, thus to further improve the quality of products.
(3) the vacuum heat treatment furnace heating speed control, and constant temperature zone temperature deviation is small. Can slow heating, so the workpiece temperature balance, each part temperature difference is small, the thermal stress is lesser, small deformation after forming. Can easily cooperate with various standard parts, to ensure that the product yield and quality. Welding not only fail to prevent oxidation of traditional process, and the welding part of high temperature, large temperature difference between the parts of components, the great amount of deformation after forming, could not reach the requirements of the product.
(4) the vacuum heat treatment furnace workpiece with the increase of temperature, the solubility of hydrogen will be more and more small, penetration workpiece internal hydrogen will gradually precipitate, so no vacuum heat treatment furnace, hydrogen embrittlement.
(5) the vacuum heat treatment is controlled by a microcomputer, small error rate, process stability and repeatability.
(6) the most important energy saving vacuum heat treatment furnace, don't need a flammable gas, and controlled atmosphere than, save raw materials, low cost, suitable for mass production.
