Abstract
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 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).
Claims8
A method for producing ingots (1) from metal having a cross-sectional area of more than 0.1 m2, liquid metal (2) being discharged either directly from a casting ladle (11) or via a tundish (12) into an ingot mold (15) open at the bottom, the at least partially solidified ingot (1) being withdrawn from the ingot mold (15) in the direction of a longitudinal axis (5) of the ingot (1) using a withdrawing tool (28) which is vertically movable in the direction of the longitudinal axis (5) and on which the ingot (1) is at least indirectly disposed, and the ingot (1) being at least temporarily rotated about its longitudinal axis (5), at least during the casting process,
- wherein
- the rotation of the ingot (1) is realized via a pedestal element (25) or a withdrawing tool (28) on which the ingot (1) stands with its facing side wherein the ingot (1) is rotated in an oscillating manner about the longitudinal axis (5).
