Abstract
The utility model discloses a seal plug for a bright muffle furnace outlet. The seal plug comprises an upper high-temperature resistant high-nickel alloy steel plate and a lower high-temperature resistant high-nickel alloy steel plate, wherein high-aluminum fibers are arranged between the upper high-nickel alloy steel plate and the lower high-nickel alloy steel plate; and the high-aluminum fibers and the high-nickel alloy steel plate are connected fixedly by a cylindrical high-nickel alloy connecting cylinder of which one end is provided with a high-nickel alloy compression ring. By the seal plug, the problem of burning caused by the dropping of pressing blocks at the bright muffle furnace outlet is solved, the halt failure time is reduced, the loss caused by failure is reduced, and the service life of the seal plug is prolonged.
Description
Technical field:
The utility model relates generally to the clean annealing unit field of stainless steel industry, relates in particular to a kind of bright retort furnace exit seal plug.
Background technology:
The clean annealing unit is exactly the unit that carries out continuous annealing with in the vertical retort furnace of band steel in hydrogen shield atmosphere of mill milling.This unit comprises coil of strip dolly, Abrollhaspel, welding machine, deviation correcting device, degreasing system, entry loop, bright retort furnace, outlet kink, batches and the coil of strip dolly; The present majority of wherein bright retort furnace equipment is to be provided by Austrian EBNER company.The light retort furnace adopts up type of heating, and horse not is to go up locator meams, and promptly horse not is that flange through top hangs in the body of heater; Dangle and in oil sealing, get final product in its underpart; Horse not outside is to be combustion heating chamber, is distributed with 40 burners, is used to the heat that provides annealing required.Horse not inside is a protective atmosphere, mainly is hydrogen or 75% hydrogen+25% nitrogen.
Horse not internal protection atmosphere sealing by horse not two sealing plugs of entry and exit guarantee.
Existing exit seal plug mainly is made up of resistant to elevated temperatures Langaloy steel plate, High Nickel Steel union lever, Langaloy briquetting and high aluminum fiber.Be provided with high aluminum fiber between these upper and lower two Langaloy steel plates; These upper and lower two Langaloy steel plates and high aluminum fiber are solidly connected one through a plurality of High Nickel Steel union levers of one of which end band Langaloy briquetting.Between said Langaloy steel plate and the telling Langaloy briquetting is that plane contact is connected.
This retort furnace working temperature is 1150 degree, so higher relatively to the material requirement of sealing plug composition, and steel alloy has adopted INCOLOY601H, and what fiber adopted is that AL2O3 content is 97% high aluminum fiber, and reason is that its stability under hot environment is better.Therefore its price is also higher, and price of spare parts is 1,140,000 Renminbi.
Above-mentioned horse not sealing plug existing problems is that Langaloy steel plate, Langaloy union lever and the Langaloy briquetting of sealing plug below directly exposes in the protective atmosphere of 1150 degree because this exit seal plug is suspended on the cooling section inlet through flange; Owing to be in hot environment for a long time; Said Langaloy steel plate produces distortion because of expanding with heat and contract with cold; The rough phenomenon of surface outlet; Make said Langaloy union lever receive tensile and cause fracture, the Langaloy briquetting that thereupon is connected with its plane contact bump stove that drops enters the mouth, thereby causes the equipment spark and light hydrogen; Said exit seal has 24 Langaloy briquettings beyond the Great Wall, if in operational process, drop wherein some Langaloy briquetting, keeps for causing the band steel, causes compressor emergency shutdown, even further possibly cause catching fire phenomenon and cause serious consequence.Thereby influence its serviceability and work-ing life.
The utility model content:
The utility model purpose is exactly in order to remedy the defective of prior art, a kind of bright retort furnace exit seal plug with good serviceability and work-ing life to be provided.
The utility model is realized through following technical scheme:
A kind of bright retort furnace exit seal plug; Comprise upper and lower two resistant to elevated temperatures Langaloy steel plates; Be provided with high aluminum fiber between upper and lower two Langaloy steel plates, it is characterized in that: the Langaloy connecting cylinder that has an arc Langaloy pressure ring through the one of which end between said high aluminum fiber and the described Langaloy steel plate is fixed with one.
A kind of bright retort furnace exit seal plug is characterized in that: the Langaloy steel plate of said Langaloy pressure ring and bottom adopts and is welded to connect.
A kind of bright retort furnace exit seal plug is characterized in that: it is the high aluminum fiber of 70-75% that said high aluminum fiber adopts AL2O3 content.So, reduce spare part expense and rehabilitation expense, reduced production cost simultaneously.
The utility model replaces to the Langaloy connecting cylinder with the Langaloy union lever in the prior art, so, and the difficult phenomenon that falls of breaking.Simultaneously, the Langaloy steel plate of Langaloy pressure ring and bottom adopts and to be welded to connect, and has solved sealing plug and has fallen briquetting and cause ignition issues, thereby reduced the machine halt trouble time, and the loss that brings of fault, has prolonged the work-ing life of the utility model.
The utility model has the advantages that:
The utility model has solved because of bright retort furnace exit seal plug falls briquetting and has caused the technology of catching fire, and has reduced the time of machine halt trouble, has reduced failover and the loss that brings, has prolonged the work-ing life of the utility model.
Description of drawings:
Fig. 1 is the front view of the utility model.
Fig. 2 is the upward view of the utility model.
Embodiment:
Referring to accompanying drawing.
A kind of bright retort furnace exit seal plug; Comprise upper and lower two resistant to elevated temperatures Langaloy steel plates 1,2; Upper and lower two Langaloy steel plates 1, be provided with high aluminum fiber 3 between 2, high aluminum fiber 3 and described Langaloy steel plate 1, the Langaloy connecting cylinder 5 that has an arc Langaloy pressure ring 4 through the one of which end between 2 are fixed with one.
It is the high aluminum fiber of 70-75% that high aluminum fiber 3 adopts AL2O3 content.
Claims (3)
1. bright retort furnace exit seal plug; Comprise upper and lower two resistant to elevated temperatures Langaloy steel plates; Be provided with high aluminum fiber between upper and lower two Langaloy steel plates, it is characterized in that: the Langaloy connecting cylinder that has an arc Langaloy pressure ring through the one of which end between said high aluminum fiber and the described Langaloy steel plate is fixed with one.
