NOZZLE FOR A HOT-DIP COATING SYSTEM AND METHOD FOR OPERATING SAME

The invention relates to a nozzle (9) for a hot-dip coating system for a flat product (11), said nozzle extending from the outlet of a continuous furnace (10) into a melt (13) below the coating bath level (12) and isolating the flat product (11) from the surroundings. At least one suction unit (3) and a blowing unit (1) are provided, and the at least one suction unit (3) is arranged between the atleast one blowing unit (1) and the coating bath level (12). The invention is characterized in that a pressure equalizing unit (7) is arranged between the blowing unit (1) and the outlet of the continuous furnace (10), and a first pressure sensor (14.1) is provided at the outlet of the continuous furnace (10) and a second pressure sensor (14.2) is provided between the coating bath level (12) and the pressure equalizing unit (7). 本发明涉及用于扁平产品(11)的热浸镀层设备的风口支管(9)，该风口支管从连续炉(10)的出口延伸到镀层浴液面(12)下方的熔体(13)中，并使扁平产品(11)与周围环境隔离，其中设置有至少一个抽吸单元(3)和一个吹入单元(1)，并且该至少一个的抽吸单元(3)设置在该至少一个的吹入单元(1)和镀层浴液面(12)之间，其特征在于，在吹入单元(1)和连续炉(10)的出口之间布置有压力补
