Abstract:
A method for arranging jet cleaning nozzles comprising: arranging multiple rows of nozzles in a parallel and uniform manner along a lengthwise direction of a metal plate strip; arranging the nozzles in each row at an equal interval; arraying adjacent rows of nozzles in a staggered manner along the widthwise direction of the metal plate strip so as to form a nozzle matrix; wherein each nozzle is perpendicular to a moving direction of the metal plate strip, and the perpendicular distance of each nozzle to a surface of the metal plate strip is the same. Through the method for arranging jet cleaning nozzles, nozzles can be flexibly controlled based on the change of the geometric relationship between nozzles, in order to implement efficient and continuous descaling on the surfaces of a metal plate strip with different width specifications and different requirements on the descaling speed. In this way, waste of energy and water resources occurred when changing specifications is avoided, and the phenomenon that upper and lower nozzles spray to each other is also avoided, thereby achieving flexible and efficient control over the arrangement mode of jet cleaning nozzles for descaling.

Claim (Index 6):
The method for arranging jet cleaning nozzles according to  claim 1 , wherein when a width of the metal plate strip in a production line changes and produces a metal plate strip of a certain target width in a width range of cleaning, in order to assure that all nozzles can conduct efficient descaling to the plate, the nozzles comprises following adjustment:\n in a vertical direction of the surface of the metal plate strip, that is namely a Z direction, setting a moving distance as \u0394c; setting a direction moving close to the metal plate strip as a negative movement, wherein a value of \u0394c is a negative value; setting a direction moving away from the surface of the metal plate strip as a positive movement, a value of \u0394c is a positive value; wherein the following formula is satisfied:\n \u0394 c ={[( L 1 \u2212L 0 )\u00d7 ctg\u03b1]/n }\u00b7(1+ K ) \n wherein: L 0 \u2014a basic width value of the metal plate strip, mm; L 1 \u2014an adjusting target width value of the metal plate strip, mm; \u03b1\u2014a unilateral divergence angle of jet flow symmetric section of the nozzle, which is determined by the property of a nozzle , degree; n\u2014the number of nozzles of two adjacent rows; K\u2014a compensation coefficient of a jet flow characteristic of nozzles \u22120.5\u02dc0; in the widthwise direction of the metal plate strip i.e. the X direction, each row of the nozzles has a central line of the plate width as a symmetry center, and when the nozzles move close to the center line of the plate width, a distance between adjacent two nozzles in each row changes with a variation 2\u0394a, which is satisfied by:\n \u0394 a =( L 1 \u2212L 0 )/( n \u22121).
