Abstract: 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 includes controlling 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.

CPC classification number: B22D11/115
Abstract: The present invention provides a tundish for continuous casting, the tundish having an inner volume including an inlet portion including an inlet for receiving molten metal, an outlet portion including at least one outlet for discharging molten metal, and a flow separator. The tundish further includes an EMS stirrer for electromagnetic stirring, wherein, the flow separator is positioned between the inlet portion and the outlet portion, the EMS stirrer is disposed outside of the tundish, at a vertical position below the top of the inner volume of the tundish and above the bottom of the inner volume of the tundish, the EMS stirrer is disposed to make the molten metal in the outlet portion flow in a horizontal direction, and the flow which is directly induced by the EMS stirrer flows away from the inlet.
