A method for ejecting solute-enriched liquid metal left in the central region of a continuously cast slab at the final stage of solidification using sequential forging with specified dies is proposed. In the present forging method, not only striking but also squeezing with the dies is applied to attain smooth ejection of the liquid metal. The deformation behavior of the slab in the sequential forging is simulated by the viscoplastic finite element method, and the shape of the interface between the solidified shell and liquid metal in the forged slab is calculated.
