<p><P>PROBLEM TO BE SOLVED: To provide a cleaning device capable of rapidly evacuating a dross pump on the occasion of strip meandering. <P>SOLUTION: A steel strip A guided to a sink roll P2 installed in molten metal in a hot dipping bath is introduced diagonally from the upper side to the lower side while being surrounded by a snout, and then guided upwardly. A pair of a discharge port 1 and a suction port 2 are provided at the liquid level within the snout so as to generate a liquid flow in the vicinity of the steel strip along its width direction, and a discharge pump 5 and a suction pump 6 are provided, as dross pumps, respectively on the ports through a discharge conduit 3 and a suction conduit 4. In a horizontal section of the snout surrounding the steel strip, an inlet sidewall facing an outlet sidewall close to a part in which the steel strip A rises and goes out of the bath P1 is raised substantially vertically from the lower end to about the molten metal level in the whole width extending from the discharge conduit to the suction conduit side. The device includes a detection means for steel strip meandering, and a moving means capable of rapidly evacuating, in response to a signal therefrom, the dross pumps. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
