A device and a control method for actively controlling the flow direction of molten steel at the outlet of a tundish passage in multiple modes

Abstract

The application provides a device and a control method for actively controlling the flow direction of molten steel at the outlet of a channel of a tundish in a multi-mode, and belongs to the technical field of induction heating of a tundish in continuous casting. The device comprises a channel tundish body, which comprises a pouring chamber, a pouring chamber and at least two heating channels connecting the pouring chamber and the pouring chamber; an induction heating device is arranged on the heating channel and close to one side of the pouring chamber; a multi-mode flow control device is arranged between the induction heating device and the pouring chamber, and a driving force perpendicular to the axis of the heating channel is generated. By adding a multi-mode flow control device at the outlet of the heating channel and combining the control method provided by the application, the molten steel can be precisely temperature-compensated, and the direction of the molten steel flowing out of the heating channel can be actively controlled.
