[0001] The present invention relates to a wide-area nozzle unit and an alien substance removing apparatus having the same,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wide-area nozzle unit and a foreign substance removing apparatus including the same. More particularly, the present invention relates to an apparatus for removing foreign matter adhered to a subject such as a strip conveying roll.

In general, a strip steel rolled in a thin plate is supported on a plurality of rolls, and is continuously processed to be subjected to various processes, thereby producing a product meeting the requirements demanded by the customer.

Here, the role of transferring the strip to the various processes is performed by a conveying device composed of a plurality of conveying rolls.

However, since such a transport roll is made of urethane or the like, when a certain period of time has elapsed, a large amount of foreign matter adheres to or adheres to the surface of the transport roll.

Such foreign matter may cause a problem of causing a dent, such as irregularities on the surface of the strip being conveyed, to cause a lag.

Conventionally, in order to solve such a problem, a stationary blade was closely fixed to the surface of a strip conveying roll, and then the conveying roll was rotated to remove foreign substances such as magnesium oxide (MgO) powder on the surface of the conveying roll.

However, when the foreign matter is removed by a conventional method, foreign substances such as magnesium oxide powder can not be completely removed from the surface of the transfer roll.

Further, even in the case of the foreign matters separated from the conveying roll, a part thereof falls on the upper surface of the conveyed strip and comes into contact with the conveying roll again, thereby causing a defect that a groove is formed on the surface of the conveying roll by foreign substances.

Therefore, it is necessary to study a wide-area nozzle unit and a foreign matter removing device for solving the above-mentioned problems.
