In the past, the strip cleaning operation was performed by using the nozzle injection method 103 of the nozzle injection method fixed in a predetermined direction and a predetermined position, the conventional injection device 103 such a degree when the width of the strip changes or meandering occurs. According to the characteristics of the line where continuous operation is not possible, and nozzle clogging due to the characteristics of the line where continuous work is performed, there are time constraints and difficulty in penetrating the blocked nozzle, and there is a high risk of safety accident. I have a problem.

In addition, as a method for removing a specific foreign material 101 on the surface of the strip 102, a method of increasing or decreasing the roll driving speed or increasing the supply amount of the cleaning liquid is used. The method increases the load of the line, and the method of increasing the supply amount of the cleaning solution causes an increase in the amount of the cleaning solution used, resulting in a cost increase and environmental pollution. Furthermore, the width of the material to be worked on is changed from time to time, and the work is performed. Since the nozzles of the injector are sprayed at fixed positions by width, the cleaning liquid is continuously sprayed from the nozzle to the empty space even when the width of the material is reduced. It causes waste, and fixed nozzles each spray only a predetermined position, so that the entire surface of the strip is not evenly cleaned.

Accordingly, the present invention is to solve the conventional problems as described above, it is possible to cleanly remove and remove the foreign matter on the surface of the steel sheet strip rolling in the rolling process requiring continuous operation without affecting the ongoing strip of the strip In the case of width change or meandering, it is possible to perform the optimal cleaning operation in each case and also to provide a multi-functional spraying device with improved strip surface cleaning ability to perform more uniform cleaning of the strip surface to be worked on.
