Abstract: The disclosure relates to a method for operating a cooling chamber in a strand guide device and the strand guide device 10 as such. The strand guide device serves to deflect a freshly cast strand, typically made of metal, into the horizontal. During the deflection, the cast strand passes through a cooling chamber 1 inside the strand guide device 2, in which it is sprayed with a coolant 33, with the formation of steam 5. The steam forms at least a steam-air mixture 5? with sucked-in secondary air, which is sucked out of the cooling chamber by a suction device 20. In particular, in order to reduce the pollutant content of the sucked-in and sucked-off steam-air mixture 5? and its emission into the environment, the present invention provides for pollutants, primarily dust, located in the steam-air mixture 5? by a separator 6, 6? to deplete.

Abstract: A method and device for driving the support rolls of a continuous casting machine for liquid metals, which support rolls form a strand guide for the continuously cast strand. The strand guide includes electrically driven individual support rolls and/or hydraulically adjustable support roll segments. An automatic load balance control system for the drives is used as the sum of the individual forces for casting speed, motor torque, motor speed, and standard correction factors and is provided with individual adjustment of torque and speed of each drive support roll motor. A total driving torque for all drives is determined from the normal force of the driven drive support rolls and proportionately transmitted to each support roll in such a way that a static base setting of the torque distribution is used as the basis for the specific load capacity of each drive support roll.
