Description

Technical Field

[0001] The utility model relates to the field of sintering furnace doors, in particular to an automatically opening and closing furnace door for a sintering furnace. Background Art

[0002] A sintering furnace is a furnace that, at high temperature, causes the solid particles of ceramic green bodies to bond with each other, causing the grains to grow, while the voids (pores) and grain boundaries gradually decrease. Through the transfer of matter, the total volume shrinks, the density increases, and finally a dense polycrystalline sintered body with a certain microstructure is formed.

[0003] During the sintering process, the sealing of the sintering furnace needs to be ensured, so it needs to be sealed with the furnace chamber after closing. Traditional furnace doors usually achieve sealing between the furnace door and the furnace chamber through locks, which requires manual on-site operation. Due to the high temperature in the furnace chamber, the hot air in the furnace chamber during manual furnace opening will bring danger to the staff, which is very inconvenient. Therefore, it is necessary to develop a furnace door that can be opened and closed automatically. Utility Model Content
