ABSTRACT:
In a process and apparatus for forming an ingot having a length at least twice as great as its characteristic sectional dimension, droplets of molten metal are sprayed onto a catching surface of a dummy bar which is rotated about its axis and moved in a removal direction along its axis. Layers of spray built up on the catching surface form an ingot. Boundary surfaces may be provided for shaping one of the surfaces of the formed ingot. In the case of a hollow ingot, the boundary surfaces are in the form of a partially cylindrical mandrel extending axially into a hollow dummy bar.
