Abstract
The utility model discloses a removal of hydrogen system of descaling bath for belted steel, including the descaling bath, the descaling bath on be connected with an exhaust duct, exhaust duct be connected with a hydrogen reaction, the hydrogen reaction be connected with the recovery reservoir through drainage tube. In this way, the utility model provides a removal of hydrogen system of descaling bath for belted steel can effectively reduce the probability that metal surface formed banding little tympanic bulla, can be in belted steel pickling process, in time get rid of partial hydrogen atom molecularization and the hydrogen that forms, and effectively improve the yield of belted steel, avoid forming defects such as pickling bubble, black crack, simple structure, safe and reliable in the metal because of the hydrogen molecule permeates.
Description
Technical field
This utility model relates to strip pickling slot device field, particularly relates to the dehydrogenation system of a kind of strip steel descaling bath。
Background technology
Strip steel rust cleaning processes mainly through Physical and chemical method, and wherein, chemical method is eliminated rust by pickling line, and rust cleaning speed is fast, rust cleaning thoroughly, and is subject to the welcome of strip steel calendering processing industry。Pickling can wash the defects such as the iron scale on raw material surface, rust staining off, makes smooth surface clean, both can avoid the accident such as broken belt, steel bonding occur when rolling, it is possible to so that finished surface is smooth, it does not have black speck rusty stain。
But the operation of existing acid pickling and rust removing there is also certain deficiency, such as, owing to sour with exposed metal function generates hydrogen, and hydrogen penetrates in the crystal lattice of metal from acid solution, and make it deform, make hydrogen more to metal internal diffusion after deformation, make metal creates the internal stress causing hydrogen embrittlement so that metal surface forms the little bubbling in strip, in black minute crack after breaking, after rolling, bubble crack can extend expansion, causes the impact flexibility of product to reduce。
Utility model content
This utility model is mainly solving the technical problems that provide the dehydrogenation system of a kind of strip steel descaling bath, the probability reducing the little bubbling that metal surface forms strip can be imitated, can in strip pickling process, the hydrogen removing part hydrogen atom molecularization in time and formed, is effectively improved the yield rate of strip steel。
For solving above-mentioned technical problem, the technical scheme that this utility model adopts is: provide the dehydrogenation system of a kind of strip steel descaling bath, it is characterized in that, including: descaling bath, described descaling bath is connected to a discharge duct, described discharge duct is connected to a hydrogen reaction groove, and described hydrogen reaction groove is connected to recovery reservoir by Drainage pipe。
In one preferred embodiment of this utility model, the junction of described discharge duct and descaling bath is provided with air-introduced machine。
In one preferred embodiment of this utility model, in described hydrogen reaction groove, it is marked with lead dichloride solution。
In one preferred embodiment of this utility model, described discharge duct, hydrogen reaction groove and reclaim reservoir and be sealed attachment structure。
The beneficial effects of the utility model are: the dehydrogenation system of strip steel descaling bath provided by the utility model, can effectively reduce the probability that metal surface forms the little bubbling of strip, can in strip pickling process, the hydrogen removing part hydrogen atom molecularization in time and formed, it is effectively improved the yield rate of strip steel, avoid, because hydrogen molecule penetrates into, metal forms the defect such as pickling bubble, black crack, simple in construction, safe and reliable。
Accompanying drawing explanation
In order to be illustrated more clearly that the technical scheme in this utility model embodiment, below the accompanying drawing used required during embodiment is described is briefly described, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the premise not paying creative work, it is also possible to obtain other accompanying drawing according to these accompanying drawings, wherein:
Fig. 1 is the structural representation of dehydrogenation system one preferred embodiment of a kind of strip steel descaling bath of this utility model；
In accompanying drawing, the labelling of each parts is as follows: 1-descaling bath, 2-discharge duct, 3-hydrogen reaction groove, 4-Drainage pipe, 5-reclaim reservoir, 6-air-introduced machine。
Detailed description of the invention
Technical scheme in this utility model embodiment will be clearly and completely described below, it is clear that described embodiment is only a part of embodiment of the present utility model, rather than whole embodiments。Based on the embodiment in this utility model, all other embodiments that those of ordinary skill in the art obtain under not making creative work premise, broadly fall into the scope of this utility model protection。
Referring to Fig. 1, this utility model embodiment includes:
A kind of dehydrogenation system of strip steel descaling bath, it is characterized in that, including: descaling bath 1, described descaling bath 1 is connected to a discharge duct 2, described discharge duct 2 is connected to a hydrogen reaction groove 3, and described hydrogen reaction groove 3 is connected to recovery reservoir 5 by Drainage pipe 4。
Described discharge duct 2 and the junction of descaling bath 1 are provided with air-introduced machine 6, accelerate the mass rate of emission of surplus hydrogen in descaling bath。
Being marked with lead dichloride solution in described hydrogen reaction groove 3, hydrogen and lead dichloride solution react and generate hydrochloric acid solution and precipitation, and hydrochloric acid solution enters in recovery reservoir 5 and carries out recycling。
Described discharge duct 2, hydrogen reaction groove 3 and reclaim reservoir 5 and be sealed attachment structure。
Utility model works principle: the hydrogen of effusion from acid solution is sucked discharge duct 2 by air-introduced machine 6, passes in hydrogen reaction groove 3, generates hydrochloric acid solution with lead dichloride solution reaction, then is entered by hydrochloric acid solution in recovery reservoir 5 and recycle。
The dehydrogenation system of strip steel descaling bath provided by the utility model, can effectively reduce the probability that metal surface forms the little bubbling of strip, can in strip pickling process, the hydrogen removing part hydrogen atom molecularization in time and formed, it is effectively improved the yield rate of strip steel, avoid, because hydrogen molecule penetrates into, metal forms the defect such as pickling bubble, black crack, simple in construction, safe and reliable。
The foregoing is only embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every equivalent structure utilizing this utility model description to make or equivalence flow process conversion; or directly or indirectly it is used in other relevant technical field, all in like manner include in scope of patent protection of the present utility model。
