Description
Technical field
The utility model relates to belt steel rolling technical fields, more particularly to a kind of dress of improvement planisher foreign matter indentation
It sets.
Background technique
Product does not conform to caused by high speed continuous acid-washing wet jetting piles line in the prior art is pressed into because of foreign matter, influences client's use,
It is serious to restrict normal production.
Strip temperature after air drier is about 100 DEG C, and the pass line roller before planisher is entered after 20m, is made
Pass line roller, crease-resistant roller are in the condition of high temperature, planisher is wet jetting piles, after leveling precision is stained with pass line roller, crease-resistant roller, high temperature
Agglutination generates a large amount of sticking foreign matters.
A large amount of black foreign matters will be accumulated on pass line roller before planisher every 4 hours, black foreign matter can be adhered to band
Steel surface can generate indentation or planisher roll marks after planisher.The foreign matter indentation about 0.3% monthly therefore generated.Every time
It is cleared up it was found that foreign matter can all be shut down about 10 minutes, daily about shutdown 60min, monthly about 30 hours.
Increase water pipe in front of pass line roller in the prior art, pass line roller is rinsed with water pipe, since water has
Limit, though pass line roller temperature is declined, roll surface still has the agglutination of part foreign matter, and pass line roller edge contacts mill with steel edge portion
The region agglutination of damage is more obvious, and good using system leveling precision cleaning effect, the small cooling effect of water is poor, though overall effect
There is significant change, but is not thorough.
Pass line roller Superficial Foreign Body is aggregated before how eliminating planisher, and improving plate face foreign matter indentation defect is the utility model
Technical problems to be solved.
Summary of the invention
The utility model provides a kind of device of improvement planisher foreign matter indentation aiming at above-mentioned defect.This
Device can be to the foreign matter thorough cleaning of belt steel rolling line roller surface and the crease-resistant roller surface agglutination of planisher entrance, after cleaning is smooth
Plate face guarantees that belt steel surface is clean, and the device cost design is cheap, and maintenance cost is low, easy to operate, is hardly damaged, and increases flat
The service life of complete machine roll and the squeeze roller at rear, withdrawal straightening machine roller.
A kind of device technique scheme of improvement planisher foreign matter indentation of the utility model is, including spray beam, spray beam setting
The upper and lower surface of strip is exported in planisher pass line roller front side top, crease-resistant roller front side lower section, planisher, sprays beam away from roll line
Roller or crease-resistant roller or vertical range with steel plate surface are 150mm ~ 200mm, spray and are provided with nozzle on beam, nozzle is defeated with desalted water
Pipeline is sent to connect.Spraying the water that the nozzle on beam sprays is fan-shaped surface, and phase mutual is interlocked.
Spraying setting on beam, there are three with top nozzle.
100-300mm, preferably 200mm are divided between nozzle.
Nozzle positioned at planisher pass line roller front side top is 30 ° ~ 60 ° with vertical direction angle towards pass line roller；
The nozzle of lower section is 30 ° ~ 60 ° with vertical direction angle towards crease-resistant roller on front side of the crease-resistant roller of planisher；Planisher exports band
The nozzle of the upper and lower surface of steel is 30 ° ~ 50 ° with vertical direction angle towards strip approach axis.
Nozzle injection pressure is 150 ~ 500Kpa.
Spray beam above pass line roller largely rinses pass line roller with desalted water, by roller cool to room temperature and with
Under, adherency of the roller to foreign matter is reduced, a large amount of pressure water clears up roller surfaces, while the foreign matter under cleaning being taken away
Plate face.
Spray beam below crease-resistant roller is cooled down and is cleared up to roller with desalted water, and foreign matter and water are left automatically by gravity
Roll surface.
The spray beam of planisher outlet strip upper and lower surface to plate face blowing mainly by achieving the purpose that reduce foreign matter.
The utility model has the following beneficial effects:
1, the foreign matter thorough cleaning that the present apparatus can be aggregated belt steel rolling line roller surface before planisher, guarantees belt steel surface
Completely.
2, the crease-resistant roller surface foreign matter agglutination of planisher entrance is eliminated, plate face foreign matter defect is eliminated.
3, smooth rear plate face is cleaned, plate face foreign matter is reduced, reduces surface defects, can ensure the life of all specifications, steel grade
Production can meet strip surface quality requirement.
4, the device cost design is cheap, and maintenance cost is low, easy to operate, is hardly damaged.5, increase temper mill roller and
The service life of the squeeze roller at rear, withdrawal straightening machine roller.
After improvement, therefore defect caused by the foreign matter indentation generated reduces 0.3%, and foreign matter ratio of defects is made to be reduced to 0.1%
Below.
It is calculated according to 1,200,000 tons of annual output, the foreign matter indentation defect year reduction 1200000*0.3% generated by planisher=
It 3600 tons, is calculated according to 300 yuan of price difference of qualified product after degradation and substandard products, Nian Xiaoyi=3600*300=1,080,000 yuan.
The device makes pass line roller surface no longer generate foreign matter, to reduce downtime, guarantees more productions
Time reduces the calculating of shutdowns in 12 hours with every monthly average, and 1 ton of steel of every production can make a profit 300 yuan, December * 100 tons of * 12 hours/
* 300 yuan/ton=4,320,000 yuan of hour.
About 5,400,000 yuan/year of total benefit.
