ABSTRACT:
A method of controlling relative movement between an ingot and a mold consists of monitoring the level of the metal pool in the mold by measuring the voltage between the ingot and a mold section disposed above the metal pool, in contact with the bath of molten slag and insulated electrically from the ingot and from the ingot-forming mold section; comparing an instantaneous value of said voltage with a predetermined value and varying the relative speed of the ingot and the mold depending on a signal proportional to the difference between the instantaneous and the predetermined values of said voltage so that the predetermined level of the metal pool is restored.
