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.

A process for forming an ingot having a length at least twice as great as a characteristic sectional dimension thereof, comprising the steps of: spraying droplets of molten metal from spray means and in a first direction; positioning an element having a catching surface in the path of said sprayed droplets; providing a boundary surface adjacent said catching surface; rotating said catching surface about an axis angularly spaced from said first direction by between 90°and 180°, whereby layers of said sprayed droplets are evenly applied to said catching surface to form a continuous agglomerate and, when said catching surface is covered by said agglomerate, said layers are evenly applied to a catching surface of said agglomerate; and continuously moving said agglomerate along said axis as said layers are applied and at a rate such that said catching surface remains at a constant distance from said spray means, whereby a longitudinal ingot surface is formed by said agglomerate layers.
