Vacuum gas quenching furnace in daily production to pay attention to item

Heat treatment is a kind of widespread in industrial process, usually is carried out under vacuum heat treatment, this leads to vacuum gas quenching furnace is widely used in daily industrial production, so in the process of using need to pay attention to what?
Tightly squeezed vacuum seal: it is well known that most of the parts for vacuum heat treatment are conducted in airtight vacuum gas quenching furnace, thus, obtain and shake the leak rate due to the stove, ensure that does not make the vacuum degree of vacuum furnace, vacuum heat treatment to ensure parts quality most has very important significance, so a key problem of vacuum heat treatment furnace, is sufficient to have reliable vacuum sealing structure, in order to guarantee the vacuum performance of vacuum furnace, vacuum heat treatment furnace structure must be followed in the design of a basic principle, is the furnace should use airtight welding, at the same time as little as possible to open or not open hole in the furnace body, less use or avoid using dynamic sealing structure, to reduce the vacuum leak, do the most installed on the vacuum furnace parts, accessories such as water-cooled electrodes, such as thermocouple export stomach also must design the seal structure.
