Because the heating, cooling, and other operations of metal workpieces require more than ten or even dozens of actions to complete. These actions are carried out inside the vacuum heat treatment furnace, which is inaccessible to operators. Therefore, there is a high demand for the automation level of the vacuum heat treatment experimental electric furnace. At the same time, some actions, such as quenching the metal workpiece after heating and insulation, require six to seven actions and must be completed within 15 seconds. Such agile conditions to complete many actions can easily cause tension among operators and result in misoperation. Therefore, only high automation can accurately and timely coordinate according to the program.

The vacuum heat treatment of metal parts is carried out in a closed vacuum furnace, and strict vacuum sealing is well-known. Therefore, obtaining and adhering to the original leakage rate of the furnace, ensuring the working vacuum degree of the vacuum furnace, is of great significance in ensuring the quality of vacuum heat treatment of parts. So a key issue for vacuum heat treatment furnaces is to have a reliable vacuum sealing structure. In order to ensure the vacuum performance of the vacuum furnace, a basic principle must be followed in the structural design of the vacuum heat treatment furnace, which is to use airtight welding on the furnace body, and to minimize or avoid the use of dynamic sealing structures on the furnace body, in order to minimize the opportunity of vacuum leakage. The components and accessories installed on the vacuum furnace body, such as water-cooled electrodes and thermocouple outlet devices, must also be designed with sealing structures.
