Three chamber heat vacuum heat treatment
Commonly used external heated vacuum heat treatment furnace structure in order to work at a higher temperature, lower tank pressure difference inside and outside the influence of the deformation of the furnace tank, there are double vacuum design the outside hot chamber of the vacuum heat treatment furnace, where outside the furnace can design a set of low vacuum device.
In order to improve the production efficiency, there are three Chambers of vacuum heat treatment furnace structure, which are composed of the loading chamber, heating chamber and cooling chamber. Each chamber of this type of furnace has an independent vacuum system, and there is a vacuum seal between the chamber and the chamber. The cooling chamber can also be filled with nitrogen or inert gas and connected with the heat exchanger to speed up the cooling.
