Abstract (en)

[origin: CA2191225A1] An apparatus for treating a strip such as a steel sheet. A first object is to provide an electrode switching device of a simple construction. A second object is to uniform the flow of the treating liquid around the electrodes. A third object is to prevent uneven treatment caused by variation in liquid level of the treating liquid between the electrodes. To attain the first object, there is provided a switching device for fixing one of the mutually facing electrodes and moving the other. To attain the second object, flow straightening plates are provided to the electrodes to define liquid staying spaces between the electrodes and the flow straightening plates, and slots for permitting the treating liquid to uniformly flow between the electrodes from the liquid staying spaces are made in a direction perpendicular to the movement of the strip. To attain the third object, bus bars for supporting the electrodes are curved at portions supporting the electrodes, whereby the electrodes are always immersed in the treating liquid.
