[0002] Vacuum degreasing furnace is a kind of degreasing production process equipment suitable for slender rod-shaped powder metallurgy devices and ceramic products. It is mainly used for vacuum or carrier gas degreasing (wax) and high temperature sintering of ceramics, stainless steel bases, cemented carbides, high-temperature alloys, high-density alloys, magnetic materials, carbides, borides, oxides, intermetallic compounds, and oxides before sintering.

[0003] The main components of the vacuum degreasing furnace include a furnace body, a furnace door, a heating element, a vacuum system, a cooling system, a degreasing system and a control system. The furnace door is used to close the furnace cavity of the furnace body, and the heating element, vacuum system, cooling system, degreasing system and control system cooperate to achieve degreasing. After the furnace door closes the furnace cavity of the furnace body, the furnace door needs to be locked on the furnace body to avoid leaving a gap, affecting the subsequent degreasing and preventing safety hazards; however, the current degreasing furnace lacks the function of monitoring the locking of the furnace door, and the situation may occur that the door is only closed without being locked for convenience, which may affect the subsequent degreasing and pose a safety hazard.
