Abstract
A kind of cold rolling abbreviated system, including following operation: with uncoiler to coil of strip uncoiling.With straightener coil of strip carried out straightening processing end to end.Defective band is cut off with hydraulic shear.Weld end to end with what band was sheared by welding machine.Band, through entry loop, enters anacidity dephosphorization unit.Band after dephosphorization enters Continuous mill train continuous rolling by inlet of rolling mill jockey pulley.Band passes sequentially through cleaning, drying unit after Continuous mill train shuts out and enters outlet looping with milling train outlet jockey pulley.This continuous cold rolling process, owing to hot rolling raw material strip dephosphorization uses anacidity dephosphorization technique, the rolling of band uses strength to depress greatly milling train, such as eighteen-high mill, make a rolling process use the drafts that normal four-roller or six-high cluster mill need 4 to 6 frame continuous rolling to complete, 2 to 3 frames complete.This continuous rolling process floor space is little, invests little, and environmental protection and energy saving are pollution-free.
Description
Technical field
The invention belongs to band steel continuous cold rolling production technology.Can be by shorter technological process, more
Few equipment composition produces cold-strip.
Background technology
Traditional coupled pickling and tandem mill, its pickling section uses hydrochloric acid shallow slot turbulence acid dip technology, rolls
Machine section is owing to being limited by each frame ability, for meeting the drafts required for a rolling process,
Generally use 4 to 6 frame tandem forms.
Pickling dephosphorization technique is a kind of chemical dephosphorization technology, and this method is in pickling by band
Groove carries out the method that chemical reaction removes strip surface oxide skin.In order to ensure enough reactions
Time, often band to be also performed to drift through multiple descaling baths from descaling bath band out
Wash, the technical process such as drying, band enters after milling train again by 4-6 frame continuous rolling.
Whole sour rolling mill technological process is longer, and unit floor space is wide.Simultaneously because use acidity to be situated between
Matter carries out dephosphorization, and environmental pollution is bigger.
Steel surface anacidity dephosphorization technique uses mechanical system to remove the iron scale on coiled sheet surface,
And without the ground space needed for existing pickling unit, without using acid harmful chemicals thing
Matter.It is mainly by spraying dephosphorization medium to the upper and lower surface of hot-rolled sheet coil, i.e. liquid and
The mixture slurry of grain, thus remove the iron scale of strip surface.
Summary of the invention
For protecting environment, and with shorter technological process, less equipment composition produces cold rolling
Band, the present invention proposes following technical scheme: a kind of cold rolling abbreviated system, including following work
Sequence: with uncoiler to coil of strip uncoiling.With straightener coil of strip carried out straightening processing end to end.With
Hydraulic shear cuts off defective band.Weld end to end with what band was sheared by welding machine.Band warp
Entry loop, enters anacidity dephosphorization unit.Band after dephosphorization passes through inlet of rolling mill tension force
Roller enters Continuous mill train continuous rolling.Band passes sequentially through cleaning, drying after Continuous mill train shuts out
Unit enters outlet looping with milling train outlet jockey pulley.Band from outlet looping out after pass through again
Outlet is cut and is cut, and exports jockey pulley, enters coiling machine.Coiling machine, strip coil rolling, works as volume
When footpath reaches required size, it is cut cutting the place of cutting by band.A kind of cold rolling short stream
Journey technique unit, including following sequence connect equipment: uncoiler, straightener, hydraulic shear,
Welding machine, entry loop, Continuous mill train, outlet looping, cut cut, coiling machine, its feature
It is: be linked in sequence between entry loop and Continuous mill train and add dephosphorization unit and open with inlet of rolling mill
Power roller, is linked in sequence between Continuous mill train and outlet looping and adds cleaning, drying unit and milling train
Outlet jockey pulley.Dephosphorization equipment used is anacidity dephosphorization unit.Described Continuous mill train is ten
Eight roller Continuous mill train.
This continuous cold rolling process, owing to hot rolling raw material strip dephosphorization uses above-mentioned anacidity dephosphorization skill
Art, the rolling of band uses strength to depress greatly milling train, such as eighteen-high mill, makes a rolling process
Use the drafts that normal four-roller or six-high cluster mill need 4 to 6 frame continuous rolling to complete,
Completed by 2 to 3 frames.This continuous rolling process floor space is little, invests little, and environmental protection is without dirt
Dye.

Detailed description of the invention steel surface anacidity dephosphorization technique uses mechanical system to remove coiled sheet surface
Iron scale, and without the ground space needed for existing pickling unit, without using acidity
Harmful chemical.It is mainly by spraying dephosphorization Jie to the upper and lower surface of hot-rolled sheet coil
The mixture slurry of matter, i.e. liquid and particle, thus remove the iron scale of strip surface.
The invention will be further described below in conjunction with the accompanying drawings.
Hot rolling raw material coil of strip is carried out uncoiling by uncoiler 1, band end to end at straightener 2
After carrying out straightening processing, hydraulic shear 3 cut off defective band, then by welding machine 4
Band is welded end to end, to realize producing continuously.Band after welding is lived by entrance
Anacidity dephosphorization unit 6 is entered after set 5.Band after dephosphorization passes through inlet of rolling mill tension force
Roller 7 enters the 18 roller Continuous mill train 8 continuous rolling through 2 to 3 frames, is rolled into institute
Need the cold-strip of thickness.In order to ensure the pressure ability of Continuous mill train 8 and avoid roller system to beat
Sliding problem, is respectively equipped with inlet of rolling mill jockey pulley 7 and exports with milling train before and after Continuous mill train 8
10 two tension roll assembly of jockey pulley are to guarantee the hightension of Continuous mill train entrance and outlet.With
Time have emulsion residue due to band exit surface, in order to avoid milling train exports jockey pulley 10
Skid, between Continuous mill train 8 and outlet looping 11, also add cleaning, drying unit 9.
Band passes sequentially through cleaning, drying unit 9, milling train outlet tension force the most afterwards from Continuous mill train 8
Roller 10 enters outlet looping 11.Band from outlet looping 11 out after again by outlet
Power roller 12, outlet is cut and is cut 13, enters coiling machine 14.14 bands of coiling machine are rolled into
Volume, when coil diameter reaches required size, band is cut at 13 cutting cutting.
Band after cutting is unloaded coiling machine by coil stripping car.
The above, the only preferably detailed description of the invention of the present invention, but the guarantor of the present invention
The scope of protecting is not limited thereto, and those skilled in the art is in method scope disclosed by the invention
In, the design of the method according to the invention scheme and the present invention thereof in addition equivalent all should be contained
Cover within protection scope of the present invention.
