Description

Technical Field

[0001] The utility model belongs to the technical field of water retaining chains, and particularly relates to a descaling water retaining water curtain. Background Technique

[0002] In hot rolling production, the descaling water retaining chain group behind the furnace plays a role in blocking the descaling water from spraying towards the heating furnace and protecting the tapping furnace door. The existing water retaining chains are generally single chains with baffles installed on the single chains. This method has poor water retaining effect. During steel pouring, the baffle is easy to break the chain, and corrosion causes the baffle to fall off, resulting in accidents where the billet cannot pass through, seriously affecting the stability of production. Content of the Utility Model

[0003] The purpose of the utility model is to provide a descaling water retaining water curtain to solve the problems put forward in the above background technique.

[0004] To achieve the above purpose, the utility model provides the following technical scheme: a descaling water retaining water curtain, including a hanging rack, hanging plates are fixed on both sides of the lower ends of both sides of the hanging rack, three hanging tubes are fixedly arranged in parallel between the two hanging plates, the three hanging tubes are arranged in a triangular shape, the first water retaining chain is hung along the length direction on the two upper hanging tubes, the second water retaining chain is hung along the length direction on the lower hanging tube, and the first water retaining chain and the second water retaining chain form a three-layer waterproof structure.

[0005] Further, fixing rings are arranged on all three hanging tubes, and the upper ends of the fixing rings are fixed to the lower end of the hanging rack to increase the load-bearing capacity of the hanging tubes.

[0006] Further, both the first water retaining chain and the second water retaining chain are composed of hanging rings and chains, the chains are hung on the hanging rings, and the hanging tubes pass through the hanging rings.

[0007] Further, hooks are arranged on both sides of the upper end of the hanging rack.

[0008] Compared with the prior art, the beneficial effects of the utility model are:

[0009] For a single-layer water retaining chain, about 2 accidents occur every year, causing about 80 minutes of downtime, and the baffle is easy to fall off during steel pouring. In the utility model, each component is hung instead of welded, so the time for offline repair and assembly is greatly saved, and the labor is greatly reduced. The three-layer water retaining chain has good water retaining effect, and the baffle arranged on the chain is cancelled, so there will be no phenomenon that the baffle falls off due to corrosion or the baffle breaks the chain during steel pouring, and the service life is longer and more reliable.

[0014] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present utility model.

[0015] The present utility model provides a descaling water baffle water curtain as shown in Figures 1-3 including a hanging rack 1. The hanging rack 1 is made of carbon steel. At both lower ends of both sides of the hanging rack 1, hanging plates 2 are fixed. Between the two hanging plates 2, three hanging pipes 3 are fixedly arranged in parallel. The three hanging pipes 3 are arranged in a triangle. The first water baffle chain 4 is hung along the length direction on the two upper hanging pipes 3, and the second water baffle chain 5 is hung along the length direction on the lower hanging pipe 3. The first water baffle chain 4 and the second water baffle chain 5 form a three-layer waterproof structure. The chain pipe 3 is a stainless steel pipe with a length of 1700 mm and a thickness of 10 mm.

[0016] Fixing rings 31 are provided on all three hanging pipes 3. The upper ends of the fixing rings 31 are fixed to the lower end of the hanging rack 1 to increase the load-bearing capacity of the hanging pipes 3.

[0017] The length of the first water baffle chain 4 is greater than that of the second water baffle chain 5. The first water baffle chain 4 and the second water baffle chain 5 are both composed of hanging rings 6 and chains 7. The chains 7 are hung on the hanging rings 6. The hanging pipes 3 pass through the hanging rings 6. Each hanging ring 6 has 3 strings of chains 7 hung on it, and the chains 7 are 10 mm higher than the surface of the roller table, which will not affect the normal operation of the steel billet.

[0018] On both sides of the upper end of the hanging rack 1, hooks 11 are provided for fixing the hanging rack 1. The hooks 11 can also be fixing plates with openings. When in use, the hooks 11 are hung on the window of the descaling box.

[0019] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
