Abstract (en)

[origin: WO2018192903A1] The invention relates to a method for producing foundry ingots (1) from metal, in particular from steel, having a cross-sectional area of more than 0.1 m2, wherein liquid metal (2) is discharged into an ingot mold (15) open at the bottom either directly form a casting ladle (11) or via a tundish (12), and wherein, by means of a drawing piston (28), which is vertically movable in the direction of a longitudinal axis (5) of the foundry ingot (1) and on which the foundry ingot (1) is at least indirectly arranged, the at least partially solidified foundry ingot (1) is drawn from the ingot mold (15) in the direction of the longitudinal axis (5).
