てなつており、鋼ストリツプ３はこれら槽１およ
び槽２を矢印の方向に通過する間に酸洗される。
The pickling tank for steel strip coils, as shown in a schematic cross-sectional view in FIG. 5, consists of a tank 1 containing hot water and a plurality of tanks 2 containing pickling liquid arranged in series. The steel strip 3 is pickled while passing through these baths 1 and 2 in the direction of the arrow.
互いに隣り合う槽１および槽２の上面には、槽
１および槽２間を通過する鋼ストリツプ３を案内

の原因となるため、この点からも頻繁な取替えが
必要となる。 The thickness a' of the dam cap 4 cannot be increased, and is approximately 60 mm or less, from the viewpoint of ensuring mechanical quality in consideration of cracking damage caused by impact loads and wear resistance, and from the viewpoint of firing manufacturing. Therefore, cracking damage occurs due to the impact load (strike) of the steel strip 3 passing over the top surface of the dam cap 4 at high speed. In this way, if cracking damage occurs on the top surface of the dam cap 4, scratches will occur on the steel strip 3.
Replacement is required. In addition, the thickness of the steel strip 3 decreases due to sliding wear, which causes the above-mentioned cracking damage, and from this point of view as well, frequent replacement is required.
上述した割れ損傷の減少と耐磨耗性の向上のた
めに、機械的強度の大きい硬質の耐酸磁器を使用
することも考えられる。しかしながらダムキヤツ
プの硬度を高くすると、逆に高速で移動する鋼ス
トリツプ３に擦り傷が発生する。 In order to reduce the above-mentioned cracking damage and improve wear resistance, it is also possible to use hard acid-resistant porcelain with high mechanical strength. However, if the hardness of the dam cap is increased, scratches will occur on the steel strip 3 moving at high speed.
従つて、ダムキヤツプは適度の軟かさを有して
いることが必要であり、このために、ダムキヤツ
プの取替え頻度は多い。 Therefore, the dam cap needs to have appropriate flexibility, and for this reason, the dam cap is frequently replaced.

ストリツプに擦り傷の発生する危険度は大きく、
また、ラインスピードを高めることができない原
因にもなつていた。 However, inspection and replacement of the dam cap cannot be carried out without stopping the line, so there are limits to inspection and replacement, and the risk of scratches on the steel strip is high.
This also caused the inability to increase line speed.

Therefore, the purpose of this invention is to prevent cracking damage caused by impact loads on steel strips moving at high speed,
To provide a dam cap for a pickling tank that does not cause scratches on steel strips, reduces the number of line stops for dam cap replacement, and can increase line speed.
