[0002] Ceramic sealing rings are annular seals made of ceramic materials. In order to obtain the required physical and chemical properties and achieve a good sealing effect, the sealing rings need to be sintered.

[0003] The existing ceramic sealing ring sintering device is mainly composed of a furnace body, a heating system and a control system. During sintering, the ceramic sealing ring to be sintered is placed in the heating area of ​​the furnace body. Through the heating system, the temperature in the furnace is gradually increased to the temperature required for sintering the ceramic sealing ring, so that the sealing ring can be sintered to obtain the required physical and chemical properties and achieve a good sealing effect.

[0004] The existing ceramic sealing ring sintering device, when in use, requires a large opening and closing space through the side-expandable opening and closing door, which can easily lead to poor sealing and cause heat loss, affecting the uniformity and stability of the temperature in the furnace, thereby affecting the sintering effect of the sealing ring. Secondly, during sintering, the heating tube is fixed in the furnace body, which makes it easy for the ceramic sealing ring to be heated unevenly during the sintering process, resulting in different sintering degrees of different parts of the ceramic sealing ring, which is prone to cracking.

[0022] Working principle: Since the existing ceramic sealing ring sintering device requires a large opening and closing space through the side-expandable opening and closing door when in use, it is easy to cause heat loss due to poor sealing, affecting the uniformity and stability of the temperature in the furnace, thereby affecting the sintering effect of the sealing ring. Secondly, during sintering, the heating tube is fixed in the furnace body, which makes it easy for the ceramic sealing ring to be heated evenly during the sintering process, resulting in different sintering degrees of various parts of the ceramic sealing ring, which is prone to cracking. Therefore, a ceramic sealing ring sintering device is proposed to address the above problems.
