徴とする熱処理炉。 A furnace body capable of maintaining both a vacuum state and a pressurized state, a vacuum evacuation system for evacuating the inside of the furnace body to create a vacuum, and a system for introducing atmospheric gas into the furnace body to pressurize it. A heat treatment system that includes a gas supply system and a pressure control system that maintains the furnace pressure at the set value by releasing part of the atmospheric gas outside the furnace body when the furnace pressure exceeds the set value. In the furnace, the pressure control system includes a seal pot containing a sealing liquid inside, a gas release pipe whose tip is immersed in the sealing liquid in the seal pot, and a gas release pipe of the gas release pipe. A heat treatment furnace comprising a shutoff valve that is provided in the middle and is capable of maintaining a vacuum.
