ABSTRACT:
The invention relates to a device for the detection with measuring techniques of the temperature course of a metal or metal alloy melt in a container (39) which is influenceable by a heating device (22 to 24) and a cooling device (33). The temperature course is herein detected via a thermal camera (49) which is directed toward the region of the solidification front (48) of the melt. The data supplied by the thermal camera (49) are used for the purpose of determining the thermal gradient along on a coordinate of the container (39) and to control the heating device (22 to 24) according to the thermal gradient. Moreover, the data supplied by the thermal camera (49) are used for the determination of the solidification velocity of the melt to regulate the cooling device (33) in accordance with this solidification velocity.
