The invention relates to a strip steel degreasing electrolytic cell, which belongs to the technical field of a production facility of hot-galvanized strip steels. The strip steel degreasing electrolytic cell comprises a cell body, a pair of strip steel guide-in rollers which are arranged on one end of the cell body, and a pair of strip steel guide-out rollers which are arranged on the other end of the cell body, and is characterized in that the strip steel degreasing electrolytic cell also comprises a spray system, wherein the spray system is fixed on the cell body and corresponds to the upper part between the pair of strip steel guide-out rollers. The strip steel degreasing electrolytic cell has the advantages that the strip steel degreasing electrolytic cell can implement spraying on strip steels which are discharged from the cell body of the degreasing electrolytic cell, remove oil stain impurities which are adhered to the surfaces of the strip steels and come from the lye surface in the cell body of the degreasing electrolytic cell, and prevent the oil stain impurities from being carried to the next procedure, so that the strip steel degreasing electrolytic cell can guarantee the surface cleaning effect of the strip steels and provide guarantee the water scrubbing effect of the next water scrubbing procedure, and can not generate the plating leakage phenomenon in the hot galvanizing procedure.
