摘要： A method for rinsing an overflow chamber at the bath-side end of a snout of a device for hot-dip coating a metal strip is presented. The snout guides the metal strip in a protective gas atmosphere before the metal strip is coated with a metal melt. A rinsing cycle is carried out in the overflow chamber of the snout by feeding metal melt from the molten bath into the overflow chamber and at the same time, sucking and pumping said melt out of the overflow chamber back into the molten bath. This rinsing cycle can be performed even when the snout has been retracted from the melt by supplying the melt from the molten bath to the overflow chamber with a delivery pump.
