Efficient vacuum furnace heat treatment practice

   Efficient vacuum furnace heat treatment practice

Vacuum furnace is in a vacuum environment to welding products for smelting metal, firing of ceramic and metal welding construction has a strong power, such as vacuum furnace performance is superior in terms of heat treatment is the industry's leading equipment, can add magnetic vacuum perfect realization, sintering, welding, construction means such as quenching, so let the vacuum heat treatment furnace with efficient way?
1, the heat insulation used in the vacuum furnace components, should take 369 law, the introduction of furnace charging quantity as the basis of calculation and rules, can effectively shorten the time of heat preservation and heat, make the production more simple and more meaningful. And as a result of the workpiece is put footprint size different size is different also, so you should take a different formula, make the heat insulation of the workpiece more reasonable, not only increases the production efficiency and saves the cost of production.
2, if it is in sealed box furnace for heat treatment, then take the 369 law can improve the efficiency of controllable gas heat treatment, for economic and social benefits of ascension.
3, 369, law is the law of the application of vacuum heat treatment furnace, the 369 law can determine the heat preservation time and hardening time of different materials, and then save the construction time, heat preservation time short steel also reduced in high temperature and residence time, such as common austenitic grain size, itself is small if can get smaller martensite after quenching organization, obviously improve the toughness and plasticity.
