Abstract

An arrangement for the continuous manufacture of metal ingots by progressive crystallization below a slag layer in a mold open at the bottom. Below the bottom edge of the mold, there are distributed along the periphery of the mold, several blocking elements moveable in the direction of the ingot surface. The edges and surfaces facing the ingot are adapted to the shape of the ingot cross section, and the blocking elements may be sectors of an annular ring.
