ル７で帯鋼５表面に付着した酸液４が除去された
後、水洗槽８で水洗され、次工程へ送られる。 The steel strip 5 traveling in the direction of the arrow Z travels through the acid solution 4 into the first tank A of the pickling tank 1, crosses over the partition 2, and enters the second tank opening, and here as well as in the first tank A. The water then passes through the following third tank C and fourth tank D in the same manner. In this way, the oxide film on the surface of the steel strip 5 is removed while passing through the acid solution 4, and after the acid solution 4 adhering to the surface of the steel strip 5 is removed by the Ringer roll 7, it is washed in the washing tank 8. It is washed with water and sent to the next process.

供給管１３から循環供給される。 The acid solution 4 is supplied from the fourth tank d, and after overflowing the partition 2 and flowing sequentially to the third tank c, the second tank b, and the first tank a, it is sent to the acid recovery equipment 10 via the shot tank 14. Here, the deteriorated acid solution is treated and mixed with fresh pickling, and is circulated and supplied from a supply pipe 13 by a supply pump 12.

そのレベル差によつて一気に流れ、シヨートタン
ク１４から槽１外へ流出することになる。 However, in recent years, from the perspective of improving productivity, strip steel 5
As the strip threading speed of the steel strip 5 is becoming faster and faster, the amount of the acid solution 4 that is carried along with the strip 5 and flows back to the next tank increases, and the level of the acid solution in each tank is lower than the running speed of the strip 5. The height increases gradually in the Z direction. As a result, the liquid level in the first tank A becomes low, and the steel strip 5 is not sufficiently soaked into the acid liquid 4, resulting in a decrease in pickling ability. As the operation continues, the amount of liquid in each tank increases due to acid supplied from the supply pipe 13, and when the liquid level in the first tank A reaches the required height, the liquid level in the fourth tank D increases. When the running of the steel strip 5 is stopped, the acid solution 4 flows all at once from the fourth tank 2 side to the first tank 1 side due to the level difference, and flows out from the shot tank 14 to the outside of the tank 1. It turns out.
これを防止するには酸洗槽１の深さを深くすれ
ばよいが、設備がコスト高となると共に、酸洗４
保有量増大に伴うランニングコストが増大すると
いう欠点がある。 To prevent this, it is possible to increase the depth of the pickling tank 1, but this increases the cost of the equipment and increases the depth of the pickling tank 1.
There is a drawback that running costs increase as the amount held increases.
そこで、かかる問題を解消する手段として、図
示のように、各槽の間の仕切２上部の帯鋼支持部
材２′に近接させて液切ロール１５を設置し、該

により酸洗槽１の深さ及び酸液４の全体保有量を
増大させることなく、酸洗を十分に行うことが可
能である。 Therefore, as a means to solve this problem, as shown in the figure, a liquid draining roll 15 is installed close to the steel strip support member 2' on the upper part of the partition 2 between each tank, and the roll 15 and the steel strip support member By appropriately setting the gap H between 2' for each partition 2, the amount of acid solution 4 entrained in the strip steel 5 between each tank A to D can be suppressed, thereby reducing the depth of the pickling tank 1. It is also possible to sufficiently perform pickling without increasing the total amount of acid solution 4 held.

However, in the device according to the above-mentioned earlier proposal, the gap H between each liquid draining roll 15 and the steel strip support member 2' is adjusted depending on the specifications of the steel strip 5 and the operating conditions such as the threading speed. It is necessary to set the optimum value while checking the entrainment situation of the liner 18. Therefore, if the operation is temporarily stopped and the acid solution 4 in the pickling tank 1 is extracted, the liner 18 should be set manually. Adjustments need to be made.
また、運転中に液切ロール１５の摩耗や切損事
故等によりロール１５を交換する必要が生じた場
