<p>The present invention relates to an apparatus for flattening a steel sheet passing through an air knife in a hot dip galvanizing process. According to the present invention, the apparatus comprises: correction units which includes upper and lower correction units including front and rear correction units arranged on front and rear surfaces of a steel sheet and arranged on upper and lower sides of an air knife, wherein each of the front and rear correction units includes a shaft extended from one side of the steel sheet along the entire width of the steel sheet, multiple electrodes mounted on the shaft to be arranged along the width of the steel sheet and facing the surfaces of the steel sheet at a predetermined distance, and wires extended along the shaft to supply power for generating magnetic force to multiple electrodes; a power unit connected with the wires to supply power to the electrodes of the correction units; an input unit receiving information on the strength, thickness, and deformation of the steel sheet; and a control unit controlling the strength of magnetic force generated on each of electrode sheets of the correction units according to information input through the input unit.</p> |
