High-temperature atmosphere sintering furnace for oversize ceramic parts and sintering method of high-temperature atmosphere sintering furnace

The invention relates to the technical field of sintering furnaces, and discloses an oversize ceramic component high-temperature atmosphere sintering furnace and a sintering method thereof.The oversize ceramic component high-temperature atmosphere sintering furnace comprises a kiln, a heat preservation cover and a lifting mechanism, a feeding port is formed in the bottom of the kiln, a furnace door is detachably connected to the feeding port, and a discharging port is formed in the top of the heat preservation cover; a discharging port of the heat preservation cover can be connected with a feeding port of the kiln, and the lifting mechanism drives the kiln door to move up and down in the kiln and the heat preservation cover. The furnace has the following advantages and effects that the diameter of the oversize ceramic component can be 1.5 m or above, after the oversize ceramic component is sintered, the lifting mechanism can enter the furnace from the feeding port in the bottom of the furnace, the furnace doo
