Abstract:
To prevent over-pickling of a steel strip during pickling pause, and shorten the time required to switch between pickling operation and pickling pause, a pickling device includes: a pickling tank for storing acid solution and for pickling a steel strip by allowing the steel strip to travel therethrough while the steel strip is immersed in the acid solution; a heat exchanger for heating the acid solution in the pickling tank; a circulation tank for storing the acid solution, provided separately from the pickling tank; an acid-solution circulation unit configured to circulate the acid solution between the pickling tank and the acid-solution storage tank; and a control device configured to control the acid-solution circulation device to maintain a liquid level of the acid solution in the pickling tank at a level below a traveling height of the steel strip.

Claim (Index 5):
The pickling device according to  claim 2 ,\n wherein the liquid-level adjustment unit includes a liquid-level measurement unit for measuring a liquid level of the acid solution, and is configured to control opening and closing of the opening-and-closing valve and operation of the pump on the basis of the liquid level of the acid solution measured by the liquid-level measurement unit.
