Abstract

A 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 order to reduce the pollutant content of the sucked-in and sucked-off steam-air mixture 5′ and its emission into the environment, pollutants, primarily dust, located in the steam-air mixture 5′ are depleted by a separator 6, 6′.
