Problems solved by technology
Usually, the entrance of the existing annealing furnace generally uses a pair of openable and closable sealing rollers to seal the gas in the furnace. In this case, the gap between the sealing rollers and the gap between the sealing rollers and the furnace shell will always be There is a certain amount of leakage, which poses hidden dangers to production safety
[0003] At present, there are also sealing materials installed between the sealing roller and the furnace shell in China to prevent leakage, but the sealing effect is still unsatisfactory.

Abstract
The invention discloses an inlet sealing cover device of an annealing furnace. The inlet sealing cover is arranged outside an inlet sealing roller of the annealing furnace in a sealed mode and comprises a sealing cover body, an air suction channel which extends along the length direction of the sealing cover body and penetrates through the sealing cover body is arranged in the sealing cover body,and a narrow opening groove which extends along the length direction of the air suction channel is formed in the air suction channel. According to the inlet sealing cover device of the annealing furnace, the protective gas leaked from the sealing roller can be discharged through the air suction channel, compared with the prior art, the inlet sealing cover device of the annealing furnace is betterin sealing effect, the leakage amount is small, the potential safety hazard caused by gas leakage in the furnace is effectively solved, and the inlet sealing cover sealing device of the annealing furnace is simple to operate, convenient to maintain and long in service life.
Description
technical field [0001] The invention relates to a sealing device, in particular to a sealing device for an annealing furnace. Background technique [0002] The entrance sealing cover roll is an important equipment of the annealing furnace. Its function is not only to improve the airtightness of the annealing furnace to ensure the final quality of the strip product, but also to prevent the environmental safety hazard caused by the leakage of the hydrogen and nitrogen protective gas in the furnace. . Usually, the entrance of the existing annealing furnace generally uses a pair of openable and closable sealing rollers to seal the gas in the furnace. In this case, the gap between the sealing rollers and the gap between the sealing rollers and the furnace shell will always be There is a certain amount of leakage, which poses hidden dangers to production safety. [0003] At present, there are also sealing materials installed between the sealing roller and the furnace shell in Ch...
