The invention provides a continuous casting tundish which comprises a second-rate slab continuous casting tundish, a tundish body, a long nozzle 1, a stopper 2, a flow stabilizer 3 and a double retaining wall flow control device. The long nozzle 1 is fixed on the tundish body. The stopper 2 is fixed on the tundish body. The flow stabilizer is located below the long nozzle 1. The double retaining wall flow control device is located between the long nozzle 1 and the stopper 2 and comprises a lower retaining wall 4 and a small retaining dam 5. The small retaining dam 5 is located on the rear side of the lower retaining wall 4. By the continuous casting tundish, liquid surface fluctuating of an flow injection area can be effectively controlled, dead area proportion on the rear side of the lower retaining wall is reduced, tundish casting stoppage is lowered, and average staying time of steel liquid in the tundish is prolonged.
