Abstract
Apparatus to control continuous casting, comprising a mold provided with at least one entrance end through which liquid metal is introduced. Furthermore, according to the present invention, the apparatus to control continuous casting comprises at least one electromagnetic brake associated with the mold, configured to induce in the liquid metal recirculation flows, and a control and command unit connected at least to the electromagnetic brake and configured to manage the functioning thereof.

Apparatus to control continuous casting, comprising a mold provided with at least one entrance end through which liquid metal is introduced, at least one electromagnetic brake associated with the mold and configured to induce in said liquid metal recirculation flows, and a control and command unit connected at least to said electromagnetic brake and configured to manage the functioning thereof, wherein the apparatus comprises detection means located, at least in a condition of use, above the entrance end and each configured to detect at least a reciprocal distance with respect to the level of said liquid metal, wherein said control and command unit is also connected to said detection means to acquire the data of each distance from each detection mean, process them in relation to the positioning of said detection means, determining characteristic parameters of the development of the surface profile of said liquid metal, and command the drive at least of said electromagnetic brake based on said characteristic parameters of the development of said surface profile in order to determine predefined recirculation flows of the liquid metal.
Method to control continuous casting which provides to cast a liquid metal by introducing the latter through an entrance end of a mold and wherein, during casting, a control and command unit (18) manages the functioning of an electromagnetic brake associated with the mold, to induce in the liquid metal recirculation flows, wherein the method comprises the detection of data of at least a reciprocal distance with respect to the level of the liquid metal by means of detection means located, at least in a condition of use, above the entrance end, the processing of said data of at least a distance in relation to the positioning of said detection means, determining characteristic parameters of the development of the surface profile, and the driving at least of said electromagnetic brake based on said characteristic parameters of the development of said surface profile in order to determine predefined recirculation flows of the liquid metal.
