Along with the proposition of " controlled rolling and controlled cooling " technology, temperature controls in rolling process, seem particularly important, and current most of producer is obviously not enough in interstand cooling ability, so just causes temperature and controls difficulty, cannot meet required product quality assurance.Wherein, finishing temperature is the important parameter realizing hot strip rolling controlled rolling, the pressure that can increase next process section cooling when finishing temperature is too high, causes band steel to realize rapid drawdown within short time and short distance, reach coiling temperature requirement, like this will influence zone steel physical property.And finishing temperature is too high, certain reason is that between finishing stand, cooling capacity deficiency causes, although be provided with inverse water spray between finishing stand to control, but the product that can only be used in compared with Thin Specs, when rolling specs brings up to more than 10mm, the inverse water spray water yield is just not enough, requirement is not reached to strip temperature control, influence zone product made from steel performance, even there will be band steel nose phenomenon, production development accident.Between finishing stand, cooling water inflow is not enough, and also can restrict variety steel exploitation, have a strong impact on variety steel quality, some variety steels high to temperature requirement even cannot be produced.
Utility model content
The technical problems to be solved in the utility model is to provide between a kind of finishing stand and is with steel cooling device, and this device can increase finish rolling region cooling effect, realizes controlling finishing temperature, cancellation band steel nose phenomenon, reduces production accident, improves strip quality.
For solving the problems of the technologies described above, the utility model adopts following technical scheme:
Steel cooling device is with between a kind of finishing stand, comprise water distribution pipe, the upper cooling water pipe be communicated with water distribution pipe, lower cooling water pipe, between the upper pressure roller that upper cooling water pipe, lower cooling water pipe are separately positioned on finishing stand conveyer belt steel, between lower compression roller, upper cooling water pipe, lower cooling water pipe setting direction are vertical with the direction of conveyer belt steel, and upper cooling water pipe, lower cooling water pipe are all interval with nozzle.
Adopt this practicality of technique scheme new, compared with prior art its beneficial effect is:
Between the upper pressure roller of finishing stand conveyer belt steel, between lower compression roller, cooling water pipe, lower cooling water pipe are set respectively, and upper cooling water pipe, lower cooling water pipe setting direction is vertical with the direction of conveyer belt steel, cooling water pipe, lower cooling water pipe are all interval with in utilization nozzle to cool in the mode of spraying being with the upper surface of steel, lower surface simultaneously, ensure that the Homogeneous cooling in belt steel rolling process, eliminate band steel nose phenomenon, can the above specification of rolling 10mm, increase product specification, widen market, and improve strip quality, rate 10% of reducing the number of rejects and seconds.
As preferably, the utility model further technical scheme is:
Upper cooling water pipe, lower cooling water pipe all regulate the position of vertical direction to be fixed by Water pipe bracket.By arranging Water pipe bracket, conveniently can regulate cooling water pipe, distance between lower cooling water pipe and conveyer belt steel, so that the spread of spray of upper cooling water pipe, lower cooling water pipe is by all standing of conveyer belt steel, make this device can for production line produce different-thickness belt steel product regulate be suitable for more convenient.
One end of water distribution pipe is communicated with filter, and the other end of water distribution pipe is communicated with upper cooling water pipe, lower cooling water pipe, and filter is communicated with by conveyance conduit with cistern, and the bottom of filter and cistern is respectively equipped with filter sewage draining exit, cistern sewage draining exit.Cistern sewage draining exit and filter sewage draining exit carry out periodic exhaustion to the mud deposited in container, foreign material, prevent in nozzle operation process blocked, improve the atomization quality of nozzle.
Upper cooling water pipe, lower cooling water pipe are equipped with 2-3 and arrange nozzle, 2-3 is set and arranges nozzle, the intensity of nozzle spray can be increased, improve misting cooling effect.
Upper cooling water pipe, lower cooling water pipe are equipped with 2 row's nozzles, the angle of two row's nozzles is 40 °, and the angle between two row's nozzles and band steel place plane is respectively 80 °, 60 °.The angle of two row's nozzles is 40 °, and object is nozzle is that narrow angle sector sprays, and produces comparatively high impact forces, cooling water is formed at belt steel surface and is uniformly distributed, and improves band steel cooling effect; The mode that nozzle is 80 °, 60 ° angles with band steel is arranged, and is sprayed on band steel and easily forms flowing, increase cooling effect.
