<p><P>PROBLEM TO BE SOLVED: To provide a device for removing foreign matter in a snout capable of manufacturing a high-quality plated steel plate in which surface defect is suppressed by discharging the foreign matter sticking on an inner wall surface of the snout to the outside of the snout. <P>SOLUTION: The device for removing foreign matter in a snout is used for removing the foreign matter in the snout placed in a plating tank for hot-dip-plating a to-be-plated material, and includes a snout elevating and lowering device 6, a foreign matter peeling device 7 and a foreign matter sucking device 8. The snout elevating and lowering device 6 operates the snout 2 to move up and down when cleaning the inside of the snout 2, and positions the elevating/lowering position of the snout 2 at an arbitrary position. The foreign matter peeling device 7 peels the foreign matter sticking on the inner wall surface of the snout 2 when cleaning the inside of the snout 2, to clean the inner wall surface of the snout 2. The foreign matter sucking device 8 sucks the peeled foreign matter and the floating foreign matter on the plating bath surface in the snout 2 when cleaning the inside of the snout 2. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
