Method and device for continuous thin strip casting

A tundish for continuous thin strip casting, wherein the tundish comprises a tundish inlet, a weir, a first dam, a retaining wall separating the tundish into two chambers, a tundish outlet, and a nozzle disposed proximate to the tundish outlet;

• wherein the retaining wall is provided inside the tundish with a channel which impenetrates two chambers;
• wherein the channel is surrounded by a first induction heater, the first induction heater comprising an iron core, a coil, a refractory material and a tube;
• and
• wherein a second induction heater is disposed outside of the nozzle;
• wherein the tundish is further configured such that,
• molten steel flows below the weir located at a first side of the tundish;
• the molten steel passes the first dam and enters the channel, where the first induction heater induction heats the molten steel, wherein further, a temperature of the molten steel after the induction heating by the first induction heater is 30˜50° C. higher than that of the molten steel provided into the tundish;
• and
• the induction heated molten steel flows out from the tundish outlet at a second side opposite the first side of the tundish to the nozzle for casting the induction heated molten steel.
