Description
Technical field
The utility model relates to a kind of cooling facility for laminar flow, relate in particular to a kind of in the hot rolling cooling process broad-adjustable upper spraying laminar flow cooling device.
Background technology
The hot rolling tandem mill production line of iron and steel enterprise all will use cooling facility for laminar flow, and its major function is exactly the band steel with the finish rolling outlet, cools off fast according to the target temperature that batches setting, to guarantee the properties of product of band steel.
With Baosteel 2050 hot rolling mills is example, and its cooling facility for laminar flow has 76 groups of cooling manifolds (correspondence is a group up and down).Wherein preceding 68 groups is main cold section, and the back is a fine cold-leg for 8 groups.Generally be divided into several cooling zones, each cooling zone all has cold section cooling zone serial connection with fine cold-leg of master separately to form, and the master of cooling zone is made of some groups strong cold collector groups and the some groups of cold collector groups of master again for cold section.The cold model of layer calculate required when opening collector valve group, according to main cold section from front to back, fine cold-leg rule is from back to front set.Therefore,, all need open in each setting, therefore be in normally open basically for back 4 groups of main cold section preceding 4 groups and fine cold-leg to the setting temperature drop of coiling temperature according to finishing temperature; All there are data the position of every group of collector (apart from the last frame of finish rolling) in basic automatization control, basic automatization all needs to follow the tracks of for the position of band steel on the laminar flow roller-way in addition.Its cooling control is as follows:
At first, the process machine calculates by the cold model of layer according to finishing temperature and the coiling temperature set, and that determines main cold section and fine cold-leg cooling manifold opens the group number, and under send instructions and water valve controlled to the finish rolling basic automatization.
Secondly, after the band steel goes out the last frame of finish rolling temperature measurer measures the finishing temperature of band steel reality after by finish rolling, again the group number of opening of cooling manifold is regulated accordingly.
At last, after the batching temperature measurer and measure the actual coiling temperature of band steel after layer is cold, dynamically the laminar flow cooling manifold is opened the group number and regulates according to the desired value of setting of batching, with the coiling temperature that guarantees the band steel in setting range.It is 5 degree that the cooling water inflow of each valve group can be controlled belt steel temperature.

Kawasaki, Japan water island factory just carried out about the laminar flow edge-masking improving the research of plate shape as far back as the eighties in 20th century, Kawasaki Steel Corp. applies for a patent " cooling means of sheet metal strip and device " (open day 1987.12.16 of application in China, patent publication No. CN87100594), its cooling facility for laminar flow adopts the laminar flow jet pipe of being made up of the flat board member of a pair of qualification slit, cooling water flows through this slit and forms a cooling water screen, for regulating the passage area in this jet pipe, the flat board member of this laminar flow jet pipe has at least one can be out of shape on perpendicular to the direction of flow of cooling water, have at least a flat board to respond cooling water pressure preferably, cause that passage area changes, thereby regulate the cooling-water duct zone.The method adopts the method to laminar flow cooling manifold edge-masking, strip edge portion temperature is reduced big problem a solution is provided, but also there is weak point in this method, obviously, the shortcoming of this prior art is: when producing than ribbon steel, a large amount of cooling waters waste, and are unfavorable for the saving of the resources of production.
In addition, prior art improves strip edge portion method of temperature, its principle all is to adopt laminar flow cooling manifold limit portion is carried out blocking of certain width, and strip edge portion temperature is reduced big problem provides a solution, but also there is common weak point in this method:
1. waste resource: when producing than ribbon steel, a large amount of cooling waters that are blocked waste, and are unfavorable for the saving of the resources of production, consume the electricity charge, increase cost of water treatment.
2. influence environment: laminar flow cooling shutter brings adverse effect to the cooling water of both sides shunting to motor and laminar flow roller bed bearing seat, though taked deflector, but still to a certain extent deterioration environment that should the place.
3. fault rate height: during strip running deviation, the both sides edge-masking can not be adjusted synchronously, and when strip running deviation was big, the edge-masking of a side just can't be brought into play the effect of blocking, and can not normally use when causing strip running deviation.
4. mechanism blockage: the laminar flow cooler environment is abominable, and the stuck fault of linkage often takes place.
5. precision is not high: the shutter of this linkage is yielding, and it is undesirable often to cause both sides to block precision.
6. pile the steel rapid wear: when heap steel fault took place the laminar flow cooling section, linkage and shutter easily caused distortion or damage.
7. not having spray down blocks: this linkage can't be applied to down the cooling of spray-up stream, does not have spray-up stream radical occlusion device down, and band steel upper and lower surface inhomogeneous cooling is even, also can cause certain strip edge portion shape wave.
