Description
Technical field
The present invention relates to Mill Technology fields, more particularly, to a kind of rolling mill assembly for preventing foreign matter to be pressed into.
Background technique
Foreign matter indentation is one of hot-rolled product prevailing quality defect now, frequent additionally, due to finishing mill plate form control problem
It will cause, guide and guard wearing plate buildup, problem exposure in recent years is increasingly severe, especially the Automobile Plate of acid-cleaning plate and high quality
Similar quality problems are more prominent.So-called foreign matter indentation is exactly that grease stain, oil leak and the bearing block rotation of roll generation are thrown away
Fall the putty to be formed after the viscous ash of drier oil, generate iron scale in the operation of rolling and be attached on the relevant component of milling train, milling train by
In foreign matters defects caused by falling in red steel surface, being pressed by roll such as the corrosion rust stainings that moisture attacks generate.Before rolling mill assembly
It is equipped with one group of milling train afterwards, the buildup being adhered on wearing plate that red steel and the friction of guide and guard wearing plate generate, milling train cleaning work is again
Thoroughly, it is impossible to avoid also having the indentation of part foreign matter.
Summary of the invention
In view of the shortcomings of the prior art, technical problem to be solved by the invention is to provide a kind of milling trains for preventing foreign matter to be pressed into
Device, water spray wash away the foreign matter that surface of steel plate milling train flows down, and improve surface quality.
In order to solve the above-mentioned technical problem, the technical scheme adopted by the invention is as follows:
The rolling mill assembly for preventing foreign matter to be pressed into, the rack including milling train further includes connected nozzle and water pipe, the spray
Mouth is set on the rack, and the injection direction of nozzle is towards surface of steel plate to be rolled.
Further, the nozzle is flat burner.
The nozzle includes the nozzle I along strip width direction injection setting and the spray along the injection setting of steel band rolling direction
Mouth II.
The nozzle I is located at the rolling mill guiding side of milling train.
The nozzle II is located at before the rolling mill guiding entrance of milling train.
The rack is equipped with collector pipe, and nozzle II is located on collector pipe, and nozzle I is connected by pipeline with collector pipe.
The nozzle I is one group of nozzle, and one group of nozzle is respectively provided at the two sides of rolling mill guiding.
The side of the rolling mill guiding is equipped with mounting hole, and nozzle I is located in mounting hole.
Compared with prior art, the present invention having the advantage that
Nozzle is added in the rolling mill assembly, the foreign matter that surface of steel plate milling train flows down is washed away by nozzle spray, improves table
Face quality, structure is simple, at low cost, and cleaning foreign matter effect is obvious；And nozzle is one group, and position is reasonable, and cleaning is not deposited
In blind area.

Fig. 2 is rolling mill guiding top nozzle schematic diagram two of the present invention.
In figure:
1. rolling mill guiding, 2. nozzle Is, 3. collector pipes, 4. nozzle IIs, 5. pipelines.
Specific embodiment
Below against attached drawing, by the description of the embodiment, making to a specific embodiment of the invention further details of
Explanation.
As depicted in figs. 1 and 2, the rolling mill assembly for preventing foreign matter to be pressed into, rack and connected nozzle including milling train
And water pipe.
Nozzle is set on the rack, and the injection direction of nozzle is towards surface of steel plate to be rolled.It is washed away by the method for water spray
Fall surface of steel plate milling train and leaves sundries and buildup.
Nozzle includes the nozzle I 2 along strip width direction injection setting and the nozzle along the injection setting of steel band rolling direction
Ⅱ4.Nozzle I 2 is located at 1 side of rolling mill guiding of milling train.Nozzle II 4 is located at before 1 entrance of rolling mill guiding of milling train.
Such as the nozzle II 4 that only setting is arranged along the injection of steel band rolling direction.There are blind areas in scale removal process, clear up not thorough
Bottom.
Nozzle is flat burner, it is ensured that injection covering surface, so that it is guaranteed that cleaning effect.
Nozzle angle is adjusted, according to triangle characteristic, as nozzle angle tunes up, injection covering surface will also increase.Spray
Penetrating face maximum angle is β: tan β=210/1580,82 ° of ≈ of β=arctan (210/1580).The length d:d=that can not be covered
210*tan (82 ° -50 °)=210*tan32 ° of ≈ 131 (mm).It sprays overlay length s:s=1580-131=1349 (mm).
Although the overlay length of a nozzle is very big, belt steel surface can not be completely covered.When guide and guard two sides are all pacified
When filling nozzle I, belt steel surface can be completely covered, cleaning effect is good.
Rack is equipped with collector pipe 3, and nozzle II 4 is located on collector pipe, and nozzle I 2 is connected by pipeline 5 with collector pipe.
Nozzle I is one group of nozzle, and one group of nozzle is respectively provided at the two sides of rolling mill guiding.Preferably, the side of rolling mill guiding
It is equipped with mounting hole, nozzle I is located in mounting hole.The setting of nozzle I thoroughly solves blind area, while washing away guide and guard wearing plate side wall
The buildup generated in due course, prevents foreign matter to be pressed into, and improves surface quality.
In order to which superficial oxidation iron sheet to be removed to strip before entering milling train, therefore installation site cannot be from finishing mill working roll
It is too far.It is found through site inspection, nozzle I can choose suitable position between finishing mill inlet guide and working roll, most close
Suitable position is that the guide and guard of entrance two sides drill to increase by four nozzle Is, and two-by-two relatively, the first two main function is to remove foreign matter,
Other two is mainly for removing buildup.It is applied in combination with nozzle II, forms longitudinal and lateral three water curtain jet streams, play envelope
Stifled and souring.
The present invention is exemplarily described above in conjunction with attached drawing, it is clear that the present invention implements not by aforesaid way
Limitation, if use the improvement for the various unsubstantialities that conception and technical scheme of the invention carry out, or it is not improved will
Conception and technical scheme of the invention directly apply to other occasions, within the scope of the present invention.
