Optionally, when controlling cleaning equipment stopping cleaning, if it is determined that going out to reach cleaning standard to damper 2, then exist Hot rolling four-high mill 1 redefines the first difference when rolling to next stocking, and executes the step similar with S21, if sentencing It makes and cleaning standard is not reached to damper 2, when hot rolling four-high mill 1 completes the rolling to next stocking, repetition is held The content of row S23 to S25.

In the embodiment of the present application, control damper 2 is moved to control shown in initial position and S23 from setting position The mode that damper 2 is moved to setting position from initial position is similar, therefore does not illustrate more herein.

It optionally, can also be according to the target after control damper 2 is moved to initial position from setting position Image generates cleaning examining report for technical staff's access, wherein record the clear of damper 2 in cleaning examining report Situation is washed, for example, whether each region for recording damper 2 in cleaning examining report reaches the record of cleaning standard, such as This, enables to technical staff to be optimized and improved based on control logic of the record to dust pelletizing system 100.

It is appreciated that can be rolled in the case where hot rolling four-high mill 1 is in running order using to two by the above method Moveable damper 2 is cleaned in the gap that material is rolled, in this way, stop cleaning is avoided, to avoid influencing The rolling mill practice time.Further, it is cleaned using cleaning equipment, effectively reduces human cost, also ensure technology people The safety of member, avoids the generation of production accident.Further, since damper 2 is removable, it can be realized and flue is kept off The comprehensive cleaning of plate 2, improves the efficiency of cleaning.Further, available target image in the process of cleaning, and according to Target image determines whether to reach cleanliness standard, not only realizes the visualization of cleaning process, additionally it is possible to accurate control cleaning knot Fruit.

On the basis of the above, as shown in fig. 7, the embodiment of the invention provides a kind of dust-extraction unit 200, including dust concentration It is worth acquisition module 201, damper control module 202, cleaning equipment control module 203, cleaning determination module 204 and detection report Accuse generation module 205.

Dust concentration value acquisition module 201, for obtaining when the hot rolling four-high mill rolls current stocking The of first dust concentration value of first dust concentration detection meter acquisition and second dust concentration detection meter acquisition Two dust concentration value

Damper control module 202, for judging the of the first dust concentration value and second dust concentration Whether one difference reaches given threshold, if first difference reaches the given threshold, determines that the hot rolling four-high mill is Rolling of the no completion to current stocking before the hot rolling four-high mill rolls next stocking, controls institute if completing It states damper and is moved to setting position from initial position.

Cleaning equipment control module 203 is moved to target position for controlling cleaning equipment, controls the cleaning equipment pair The damper is cleaned, and obtains the target image after the damper completes cleaning by the cleaning equipment.

Determination module 204 is cleaned, for determining whether the damper reaches cleaning mark according to the target image Standard controls the damper from the setting position and is moved to the initial position if reaching.

Examining report generation module 205, for generating cleaning examining report according to the target image.

To sum up, a kind of dust removal method and device based on hot-rolled process provided in an embodiment of the present invention, due to damper Be relative to hot rolling four-high mill it is transportable, therefore, when the first difference reaches given threshold, can use hot rolling four-roller Gap when milling train rolls stocking, control damper are moved and control cleaning equipment and carried out clearly to damper Wash, in this way, without hot rolling four-high mill shut down when just damper is cleaned, further, since damper relative to Hot rolling four-high mill is removable, therefore in cleaning, comprehensive cleaning can be carried out to damper, to improve cleaning matter Amount, and then improve efficiency of dust collection.Further, available target image in the process of cleaning, and determined according to target image Whether reach cleanliness standard, not only realizes the visualization of cleaning process, additionally it is possible to accurately control wash result
