[0002] Vacuum atmosphere furnace, also known as oxygen-free annealing furnace, vacuum atmosphere sintering furnace, etc., is a method of sintering objects in a furnace with a certain gas. Different materials choose suitable atmosphere sintering, which is helpful for the sintering process, improves the densification degree of products, and obtains products with good performance. Vacuum atmosphere furnaces are commonly used in vacuum, hydrogen, oxygen, nitrogen and inert gas (such as argon) and other atmospheres;

[0003] The explosion-proof device of the vacuum atmosphere furnace is a key component to ensure the safe operation of the equipment. It can effectively reduce the risk of explosion in the furnace by adopting high-sealing design, setting up explosion-proof devices, and strengthening electrical and mechanical protection. However, when the furnace shell can no longer limit the expansion of the internal gas, the gas will break through the furnace shell. When the gas breaks through the shell, the potential energy stored inside is accumulated and converted into kinetic energy due to the increase in pressure, forming an impact force and carrying the furnace shell debris to the outside, which may cause harm to external personnel and thus pose a safety hazard.
