Zusammenfassung:PROBLEM TO BE SOLVED: To provide an acid cleaning apparatus in which a discharge amount of an acid cleaning liquid can be reduced.SOLUTION: An acid cleaning apparatus 1 passes a steel strip 10 through the inside of an acid cleaning tank 30 to immerse the steel strip 10 in an acid cleaning liquid W inside the acid cleaning tank 30. The acid cleaning apparatus 1 includes: a liquid draining roll 43; and a blockage plate 50. The liquid draining roll 43 is made to rotatably contact to a top face of the steel strip 10 in the acid cleaning tank 30. The blockage plate 50 is disposed to a lower part of the liquid draining roll 43 in the acid cleaning tank 30. The blockage plate 50 blocks a flow of the acid cleaning liquid W in a lower surface side of the steel strip 10. 【課題】 酸洗液の排出量を低減することができる酸洗設備を提供する。【解決手段】 酸洗設備1は、鋼帯10を酸洗槽30内に通板し、鋼帯10を酸洗槽30内の酸洗液Wに浸漬させる。酸洗設備1は、液切りロール43と、遮断板50とを含んで構成される。液切りロール43は、酸洗槽30内において鋼帯10の上面に回転可能に当接される。遮断板50は、酸洗槽30内における液切りロール43の下部に配置される。遮断板50は、鋼帯10の下面側における酸洗液Wの流れを遮断する。【選択図】 図1
