い位置に設置し、上記戻り配管口からの戻り配管
途中に酸洗槽より低いレベルに密封容器であるス
ラジ分離タンクを設け、前記スラジ分離タンクか
ら戻り配管を酸洗槽の液面と同一レベルまで上げ
て配置するとともに酸洗槽の液面と同一レベルか
ら下降させて循環タンクへ接続し、酸洗槽と前記
循環タンクの間で酸液を循環させることを特徴と
する熱延鋼帯の酸洗槽におけるスラジ除去装置。 The return piping port for the acid solution is installed at a position lower than the liquid level of the pickling tank, and a sludge separation tank, which is a sealed container, is installed at a level lower than the pickling tank in the middle of the return piping from the return piping port, and the sludge separation tank is installed at a level lower than the pickling tank. The return piping from the separation tank is raised to the same level as the liquid level in the pickling tank, and connected to the circulation tank by being lowered from the same level as the liquid level in the pickling tank, and between the pickling tank and the circulation tank. A sludge removal device in a hot-rolled steel strip pickling tank, characterized by circulating an acid solution.
