What is the working principle of vacuum furnace

Question: what is the working principle of vacuum furnace. , where will it be used?


Answer: the principle of vacuum furnace is to use the vacuum system (assembled by vacuum pump, vacuum measuring device, vacuum valve, furnace body, control system and other components) in the specific space of the furnace cavity to discharge some substances in the furnace cavity, so that the pressure in the furnace cavity is less than a standard atmospheric pressure, and the space in the furnace cavity can realize the vacuum state. This is the vacuum furnace. In order to achieve the vacuum state, there is a special "vacuum technology equipment" to extract the air around the workpiece. In order to achieve controllable atmosphere and control of different vacuum degree, air or nitrogen should be injected properly.


Vacuum furnace application: high pressure and high flow rate air quenching vacuum furnace: mainly used for vacuum heat treatment of cold and hot die steel, high speed steel, elastic alloy, high temperature alloy, stainless steel, titanium alloy, magnetic material and other materials.
