CONSTITUTION: Rinse circulating water through a circulating water cooling unit rinses a strip(2) through a spray head(60a) and a nozzle(60b) in a salt rinse tank(60). Herein, horizontal mobile bars(92a,92b) does not move right and left in a state that a rod of cylinders(61,63), and an air solenoid valve(102) is closed. In this state, the rinse circulating water gathered in a collection tub(82) is supplied along with a supply line(86) by pumping a pump(85) connected to an absorptive line(83). Herein, a rinse circulating water supply shut off valve(87) is opened by non-sensing of a sensor(72) while a sludge removal valve(88) is closed. Thus, the rinse circulation water is sprayed to the strip through each spray head and nozzle so that the salt solution is rinsed.
