Zusammenfassung:	The present disclosure relates to a method of controlling an electromagnetic stirrer arranged around a submerged entry nozzle, SEN, of a tundish provided with a stopper rod to control throughput of the tundish, the SEN being configured to provide tapping of molten metal from the tundish and the electromagnetic stirrer being configured to generate a rotating magnetic field in the SEN, wherein the method comprises controlling (S1) the electromagnetic stirrer to operate only when a gas flow rate through the stopper rod is in a first range of 1.5 NL/min to 20 NL/min. 本公开内容涉及控制电磁搅拌器的方法，该电磁搅拌器被布置在中间包的浸入式进入喷嘴SEN周围，该中间包设置有塞棒以控制中间包的吞吐量，该SEN被配置成提供熔融金属从中间包的出料，并且该电磁搅拌器被配置成在SEN中生成旋转磁场，其中，该方法包括控制(S1)电磁搅拌器仅在通过塞棒的气体流速在1.5NL/min至20NL/min的第一范围内时进行操作。
