Abstract
The utility model relates to a small furnace tuyere stock water -cooling sphere and contact flange, including a water -cooling stainless steel sphere, this water -cooling stainless steel sphere passes through fixed the linking to each other of blast furnace tuyere stock of a plurality of fixing bolt side by side and rear end, at blast furnace tuyere stock's the other end then through fixing bolt and elbow contact flange stationary phase even. Elbow after the transformation and blowpipe and well festival all contact and very tightly can not leak out, greatly reduced the air leakage rate of blast furnace, can guarantee the blast air kinetic energy of blast furnace to do benefit to the intensive smelting of blast furnace.
Description
Technical field
This utility model belongs to roughing runner Removal Technology field, relates to a kind of small furnace eyesight elbow water-cooled sphere and engagement flange.
Background technology
Small furnace tuyere device is different with big blast furnace, big blast-furnace tuyere belly pipe comprises elbow (entirety that belly pipe is fixing with elbow bolt), and small furnace tuyere device belly pipe is to be connected by pull bar with elbow, by ball face sealing (cast iron sphere, the resistance to material of internal filling), elbow is connected with joint and bustle pipe gooseneck in top, forms air-supply arrangement.
This structure also exists several obvious shortcoming: one, the castable inside elbow sphere is washed away through the hot blast of high pressure after a while, high-temperature and is etched, castable is etched that the palintrope head shoot face that comes off is the most rubescent, deformation or scaling loss (life-span short 2-3 month, the longest can be with 1 year).Two, elbow leaks out with the easy scaling loss of resistance to material of middle joint connecting place, needs to change whole elbow cost big (life-span is typically at about 1-3) after scaling loss.Three, easily leak out with middle joint connecting place due to elbow, scaling loss, rubescent the most easily occurs, even occurs burning, cause maintenance to change frequently, normal production is caused the biggest impact.Four, replacing significantly increases the labor intensity of workman frequently, adds cost of labor.
Utility model content
In order to overcome the disadvantages mentioned above of prior art, this utility model provides a kind of small furnace eyesight elbow water-cooled sphere and engagement flange, rustless steel water-cooled sphere contacts with tuyere blast pipes tightly, do not leak out, the service life making this sphere after using circulating water instead significantly extends, and improved elbow sphere is generally available 2-7；If scaling loss is leaked out after elbow top and middle joint connecting place set up flange, only need to change flange, it is not necessary to change whole elbow, greatly saved production cost, if the not slagging scorification of improved elbow or filling slag can be with the generation furnace life of blast furnace；Improved elbow all contacts with blowpipe and middle joint and the most tightly will not leak out, and greatly reduces the air leak rate of air curtain of blast furnace, it is ensured that the strengthening smelting of the blast energy of blast furnace, beneficially blast furnace.
This utility model solves its technical problem and be the technical scheme is that a kind of small furnace eyesight elbow water-cooled sphere and engagement flange, including a water-cooled rustless steel sphere, this water-cooled rustless steel sphere is fixedly linked by the blast-furnace tuyere elbow of several fixing bolts side by side with rear end, and the other end at blast-furnace tuyere elbow is then fixedly linked with elbow engagement flange by fixing bolt.
The in the reverse direction being connected with water-cooled rustless steel sphere at described elbow is provided with an air port peep-hole.
Water-cooled rustless steel sphere is provided with water-cooled rustless steel sphere water inlet pipe and water-cooled rustless steel sphere outlet pipe.
The beneficial effects of the utility model are: rustless steel water-cooled sphere being contacted tightly with tuyere blast pipes, does not leaks out, make significantly extend the service life of this sphere after using circulating water instead, improved elbow sphere is generally available 2-7；If scaling loss is leaked out after elbow top and middle joint connecting place set up flange, only need to change flange, it is not necessary to change whole elbow, greatly saved production cost, if the not slagging scorification of improved elbow or filling slag can be with the generation furnace life of blast furnace；Improved elbow all contacts with blowpipe and middle joint and the most tightly will not leak out, and greatly reduces the air leak rate of air curtain of blast furnace, it is ensured that the strengthening smelting of the blast energy of blast furnace, beneficially blast furnace.
Accompanying drawing explanation
Fig. 1 is this utility model structural representation；
Fig. 2 is eyesight elbow engagement flange top view；
Fig. 3 is water-cooled rustless steel sphere top view.
In figure: 1-blast-furnace tuyere elbow, 2-elbow engagement flange, 3-fixes bolt, 4-water-cooled rustless steel sphere, 5-water-cooled rustless steel sphere water inlet pipe, 6-water-cooled rustless steel sphere outlet pipe, 7-air port peep-hole.
Detailed description of the invention
With embodiment, this utility model is further illustrated below in conjunction with the accompanying drawings.
See Fig. 1～Fig. 3, a kind of small furnace eyesight elbow water-cooled sphere and engagement flange, including a water-cooled rustless steel sphere 4, this water-cooled rustless steel sphere 4 is fixedly linked by the blast-furnace tuyere elbow 1 of several fixing bolts 3 side by side with rear end, and the other end at blast-furnace tuyere elbow 1 is then fixedly linked with elbow engagement flange 2 by fixing bolt 3.
The in the reverse direction being connected with water-cooled rustless steel sphere 4 at described elbow is provided with an air port peep-hole 7.
Water-cooled rustless steel sphere 4 is provided with water-cooled rustless steel sphere water inlet pipe 5 and water-cooled rustless steel sphere outlet pipe 6.
Rustless steel water-cooled sphere being contacted tightly with tuyere blast pipes, does not leaks out, make significantly extend the service life of this sphere after using circulating water instead, improved elbow sphere is generally available 2-7；If scaling loss is leaked out after elbow top and middle joint connecting place set up flange, only need to change flange, it is not necessary to change whole elbow, greatly saved production cost, if the not slagging scorification of improved elbow or filling slag can be with the generation furnace life of blast furnace；Improved elbow all contacts with blowpipe and middle joint and the most tightly will not leak out, and greatly reduces the air leak rate of air curtain of blast furnace, it is ensured that the strengthening smelting of the blast energy of blast furnace, beneficially blast furnace.
