Abstract

PURPOSE: To evenly pickle the upper and under surfaces of a strip and to equalize metal losses of the strip at the upper and lower surfaces by making the space between spray nozzles in the longitudinal direction of the strip at the under surface side of the strip smaller than that at the upper surface side so that a larger amount of an acid soln. is sprayed at the under surface side.
CONSTITUTION: A strip S is introduced into a spray pickling apparatus, where it is pickled by spraying an acid soln. from nozzle headers 2. At this time, the space between nozzles in the longitudinal direction of the strip S at the under surface side of the strip S is made smaller than that at the upper surface side to arrange a larger number of nozzles at the under surface side. Thus, a larger amount of an acid soln. is sprayed on the strip S at the under surface side, and metal losses of the strip S can be equalized at the upper and under surface sides.
