る。The high-temperature strip 6 unwound from the pay-off reel 7 is continuously introduced into a sensible heat recovery device 1 containing a heat recovery medium such as water or molten salt, and is deheated and guided to a pickling tank. . The heat recovered by the sensible heat recovery device 1 is supplied to the pre-heater tank (warm water) 3 installed on the inlet side of the pickling tank 4 through the heat exchanger 5. The strip passes through a processing line such as a tension bridle roll 8, a looper 10 and a tension bridle roll 9 and enters a preheater tank 3 where it is preheated to a predetermined temperature. That is, efficient pickling can be performed by setting the strip temperature on the pickling layer-entry side to a high temperature state to equalize the temperature.
