Specific embodiment
The supply of coolant liquid when Fig. 1 is in the cold-rolling equipment of previous endless form using mixed rolling technology
The figure that system is illustrated.Steel plate 1 is rolled into defined plate thickness by work roll 2.At this point, low concentration coolant liquid is by jet pump 8
It sprays from spray head 3 to surface of steel plate, while improving the lubricity between steel plate 1 and work roll 2, work roll 2 is carried out
It is cooling.It is recovered to after spraying to surface of steel plate and the low concentration coolant liquid that is used from oil sump 11 and is set to returning for oil depot
Tank 4 is flowed, cleaning tank 7 is returned to via the filter 6 for being located at ground by reflux pump 5, and is recycled.At this point, from spray head 3 to
Low concentration coolant liquid onboard hydrops 10 of the surface towards upstream side formation length X of surface of steel plate injection.
On the other hand, high concentration coolant liquid is modulated in high concentration coolant bottle 12, using jet pump 13 from spray head 9 to
Surface of steel plate injection.The high concentration coolant liquid used by injection is recycled by above-mentioned oil sump 11, mixed with low concentration coolant liquid
It closes, is recycled as low concentration coolant liquid.In addition, the spray head 9 of high concentration coolant liquid is in order to substantially ensure that oil is attached to
The time of plate face and improve plate-out, so the eject position being set to than low concentration coolant liquid rolls on the upstream side and from work
The position of roller separating distance L to the upstream side.Here, 14 in figure are to be attached to surface of steel plate in the rolling with base before removing
Coolant liquid function water removal roll.
The low concentration coolant liquid that Fig. 2 schematically shows mill speed V and formed in the plate face of work roll approaching side
Hydrops length X between relationship.The amount for being imported into the ROLLING OIL of roll gauge changes because of mill speed V, therefore hydrops
Length X is longer when mill speed is lower, shorter when mill speed is higher.
In addition, the hydrops length X for the low concentration coolant liquid that Fig. 3 schematically shows mill speed V when reducing with from work
Make roll separating distance L and the relationship between the spray head setting position of the high concentration coolant liquid that is arranged to the upstream side, in rolling speed
When degree V is lower, there are the settings that the hydrops length X of low concentration coolant liquid is longer than the spray head 9 of work roll 2 and high concentration coolant liquid
The distance between position L, to the case where reaching the position for removing water roll 14.
In addition, Fig. 4 schematically show low concentration coolant liquid the amount of injection Q and low concentration coolant liquid hydrops length X it
Between relationship.The length X of hydrops changes because of the amount of injection Q of low concentration coolant liquid, if the amount of injection Q becomes smaller, the length X of hydrops
Shorter, if the amount of injection Q increases, the length X of hydrops increases.
Therefore, in the present invention, when mill speed V is reduced, the amount of injection Q of low concentration coolant liquid is reduced, low concentration is made
The hydrops length X of coolant liquid is shorter than the distance between the setting position of spray head 9 of work roll 2 and high concentration coolant liquid L, i.e., long-pending
The upstream side front end of liquid does not reach the setting position of the spray head of high concentration coolant liquid, thus, it is possible to by high concentration coolant liquid always to
Surface of steel plate is directly sprayed.That is, the present invention has following feature：Accordingly with mill speed V, low concentration coolant liquid is adjusted
The amount of injection Q, be achieved in the superior cold rolling of plate-out.
Fig. 5 indicates the cooling that the cold-rolling equipment of the invention of low concentration coolant liquid the amount of injection is accordingly adjusted with mill speed
One example of liquid supply system figure.Flow control valve 17 is set in the feed system of low concentration coolant liquid, based on from work
The mill speed of the drive motor 16 of roll instructs, and utilizes distributed monitoring control system (Distributed Control
System) 15 are shorter than the distance L until the eject position of high concentration coolant liquid to calculate the hydrops length X of low concentration coolant liquid
Its result is given and is set to the flow control valve 17 of the cooling liquid supply system of low concentration and makees by the amount of injection Q of low concentration coolant liquid
For opening degree instruction.
However, if by high concentration coolant liquid when mill speed reduces also with mill speed it is higher when identical amount into
Row injection, then the ROLLING OIL sprayed to surface of steel plate increases, therefore lubricity improves.But if lubricity is excessively high, becomes and draw
Act the reason rollings exception such as slide, tremble.Therefore, if also accordingly adjusting the injection of high concentration coolant liquid with mill speed
Amount, then can supply optimal oil needed for cold rolling, therefore can steadily carry out cold rolling.
In order to accordingly adjust the amount of injection of high concentration coolant liquid with mill speed, with low concentration coolant liquid the case where is identical
Ground is arranged flow control valve in the feed system of high concentration coolant liquid, is instructed based on mill speed by the spray of high concentration coolant liquid
The amount of penetrating controls in extent of amendment.
In general, rolling load is higher if mill speed increases, it is therefore desirable to increase the amount of injection of the ROLLING OIL of supply,
It, can be according to rolling speed but in the case where accordingly adjusting the amount of injection of high concentration coolant liquid with mill speed as described above
Degree sprays optimal rolling oil mass.
Embodiment
Fig. 6 is indicated in actual roll mill, makes mill speed with 200m/min, 400m/min and 1000m/min this 3
When stage is changed, low concentration coolant liquid the amount of injection Q and the hydrops of the low concentration coolant liquid formed in plate face
Relationship between length X.
Here, the A point in figure indicates mill speed V=1000mpm, the amount of injection of low concentration coolant liquid is set as maximum
QmaxHydrops length X when being rolled.At the A point, mill speed is higher, and interior processing calorific value is more per unit time,
Therefore by the injection flow of low concentration coolant liquid with maximum QmaxIt is sprayed, work roll is cooled down, but be imported into and roll
The amount of low concentration coolant liquid between roll gap is also more, therefore the length X of hydrops is shorter than work roll and high concentration coolant liquid is sprayed
The distance between head setting position L.
Here, in the case where mill speed has been slowed down because of certain reasons such as rolling stock existing defects, such as Fig. 2 institute
Show, the length of hydrops increases.For example, if mill speed V is decelerated to 400mpm from 1000mpm, the length X of hydrops is from A point
Mobile to B point, hydrops length is longer than the distance between work roll and high concentration coolant liquid spray head setting position L.
Therefore, if by the amount of injection of low concentration coolant liquid from QmaxDrop to Q1, then hydrops length X is mobile to C point, thus
Hydrops length X is shorter than the distance between work roll and high concentration coolant liquid spray head setting position L.At this point, roll cooling capacity
It is reduced because of the reduction of the amount of injection of low concentration coolant liquid, but relies on the reduction of mill speed, per unit time interior processing hair
Heat also becomes smaller, therefore does not lead to the problem of.
Even if in addition, mill speed V is further decelerated to 200mpm from 400mpm because exporting lateral coil segmentation etc.
In the case where, if the flow that low concentration coolant liquid is sprayed is contracted to Q2, then the length X of hydrops moves to D point, therefore product from C point
The length X of liquid is shorter than the distance between work roll and high concentration coolant liquid spray head setting position L.
