Description
Technical field
The utility model relates to field of metallurgical machine, particularly relates to a kind of concentration of emulsion used control device that can prevent emulsion channeling between frame.
Background technology
The emulsion circulatory system of cold continuous rolling is used for the lubricated and cooling of roll and band steel, thus improve the band steel surface quality, improve plate shape, obtain qualified cold-rolled products.Different milling trains, roll material, rolling object and technology are also different to the requirement of concentration of emulsion used.Emulsion circulatory system control has two kinds of patterns usually: pattern 1:5# frame is used smooth roll, and S1 (S2) case is for 1#～5# frame, and promptly 1#～5# frame is with same emulsion casing, and concentration of emulsion used is all 3～4%; Pattern 2:5# frame is used the hair roller, S1 (S2) case is for 1#～4# frame, the S3 case is for the 5# frame, be 1#～4# frame with a casing, concentration of emulsion used is all 3～4%, and with a casing, concentration is 0.5～1% to the 5# frame separately, handle as smooth, cleaning machine frame, the concentration value between casing differs 3%.Pattern 1 time, finally all get back to the original casing from the emulsion that casing is gone out, therefore do not relate to the problem that concentration of emulsion used changes.And adopt pattern 2 in most applications, because the concentration of emulsion used that 4# frame and 5# frame are used differs greatly,, will cause 5# frame concentration of emulsion used to substantially exceed setting value in case emulsion channeling takes place between 4# frame and the 5# frame.And the cleaning of working roll, intermediate calender rolls and the backing roll of 4# frame cooling simultaneously all is arranged in the outlet of 4# frame, only depend at ordinary times that conventional baffle plate prevents channelling between frame, so 4# frame emulsion is often fled to the 5# frame during ordinary production, the concentration of 5# frame emulsion often surpasses setting value, has a strong impact on to roll the back strip surface quality.The cold-rolling mill that has is provided with S3 to the frequent operation of falling the case of S1 (S2), alleviate 5# frame concentration of emulsion used and continue the influence that rising brings, but this operation not only takes time and effort, and DeGrain, the concentration of emulsion used of 5# frame still raises because of channelling, the still difficult stable control that reaches low concentration of S3 case and 5# frame.
The utility model content
For solving the problem of above-mentioned existence, the purpose of this utility model is: a kind of emulsion channeling device between frame that prevents is provided, and described device can stop the channelling of emulsion between different frames, remains on setting value to guarantee the concentration of emulsion used that frame is used.
The purpose of this utility model is achieved in that a kind of emulsion channeling device between frame that prevents, comprise frame and the emulsion feeder that is positioned at its below, wherein, the emulsion reflux is set between two frames, described emulsion reflux is with the stepped arrangement of dividing plate, is provided with the emulsion backflash below described dividing plate; Above the band steel between the described frame, be provided with nozzle.
Be preferably, the number of described dividing plate is the 3-5 piece.
Wherein, described emulsion feeder is positioned at the below of described emulsion reflux.
Wherein, described nozzle is used to spray compressed air.
Wherein, the injection direction of described nozzle is for to spray to the high side of concentration from the low side frame of concentration of emulsion used.
Further, the number of described nozzle is 20-30.
The utlity model has following advantage:
The emulsion that the utility model can make being used on each frame cool off and lubricate all is back to the emulsion feeder of this frame, the emulsion channeling that has prevented 4# frame higher concentration especially is to the 5# frame, solved the problem of emulsion channeling between frame from the source, guaranteed the stable control of low concentration of S3 case and 5# frame emulsion, satisfy technological requirement, guaranteed to roll the back strip surface quality.With the S3 case to S1 (S2) case frequently the operation of falling the case compare, the utility model is easy to operate, has simplified operating process.
Description of drawings
Fig. 1 is the overall structure schematic diagram of the utility model device.Wherein, the 1-nozzle, the 2-dividing plate, 3-emulsion backflash, 4-emulsion feeder, 5-is with steel, 6-4# frame, 7-5# frame.
Fig. 2 is that the A of emulsion reflux among Fig. 1 is to partial view.The flow direction of arrow 11 and 12 expression dividing plates, 2 below emulsions, arrow 13 expression emulsions are along the flow direction of emulsion backflash.The traffic direction of band steel is opposite with the direction of arrow 13.
The specific embodiment
Below in conjunction with accompanying drawing and the specific embodiment the utility model is done and to be described in further detail:
Embodiment 1
As Fig. 1, nozzle 1 assembly that band steel 5 tops are set up between the emulsion reflux unit that the utility model device is provided with by passage below between frame (being made of 3 dividing plates 2 of centre and the emulsion backflash 3 of both sides) and 4# frame 6 and the 5# frame 7 is formed.Dividing plate 2 stepped arrangements.
On Baosteel five cold rolling mills, most products adopt pattern 2 rolling, and this moment, S1 (S2) case supplied 1#～4# frame, and concentration of emulsion used is 2.5～4.0%, and the S3 case is for the 5# frame, and concentration of emulsion used is 0.5～1.5%.Nozzle 1 is installed on the calibrator protection framework; number of nozzle is 30; when rolling, the emulsion of S1 (S2) case is fed on 1#～4# frame by pipeline, and the emulsion that 4# frame outlet band steel 5 surfaces are taken out of blows back the 4# frame by compressed-air actuated purging in the nozzle 1.After emulsion falls from band steel 5 tops, because stopping of the stepped dividing plate 2 in the emulsion reflux unit, emulsion can only be along arrow among Fig. 2 11 and 12 directions to 2 liang of side flow of dividing plate, finally flow back to the emulsion feeder 4 of 4# frame along emulsion backflash 3, stopped the phenomenon of the emulsion channeling of 4# frame to the 5# frame by the direction of arrow 13.
Embodiment 2
Except the dividing plate number is 5, number of nozzle is that other are with embodiment 1 beyond 26.
Except the dividing plate number is 4, number of nozzle is that other are with embodiment 1 beyond 20.
To sum up, device of the present utility model can effectively prevent the channelling of 4# frame high-concentration emulsified liquid, thereby the concentration that has guaranteed 5# frame S3 case emulsion is controlled at 0.5～1.5%, has guaranteed to roll the back strip surface quality.The utility model device is easy to operate, uses on the cold rolling milling train of Baosteel five, and is respond well.
