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 device for discharging exhaust air from the surroundings of a metal strip. The device has air quantity boosters with an opposing suction device on the other side of the conveying path in the blowing direction in order to suction and discharge the airflow generated by the air quantity boosters together with the exhaust air. In order to reduce costs for the operation of the device, a sensor device is provided in order to detect whether the metal strip is present or not and at which speed the metal strip is being moved. Additionally, a controller is provided in order to adjust the delivery rate of the air quantity boosters and the suction device depending on the measured speed.
