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.
