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′.

Abstract: The invention relates to an apparatus and to a method for separating condensable materials from an exhaust air stream. Known apparatuses of this type typically comprise a flow duct for the correspondingly contaminated exhaust air, wherein a first separator (114) and a second separator are connected in series in the flow duct (110). A fan is typically connected downstream of the two separators and operates as a suction fan in order to draw the exhaust air through said separators and to discharge the exhaust air to the environment after it has passed through both separators. In a rolling mill, order to observe predefined limit values for the proportion of condensable materials in exhaust air streams before such streams are discharged into the ambient air, the present invention provides for the exhaust air to be separated at the rolling mill itself, and, downstream, for the fan to be placed not at the outlet of the separators but upstream of the first separator. In addition, a scrubber is connected between the fan and the first separator, and a cooling device is provided between the first and second separator. Following the last of the separators, the exhaust gas streams A and B are reunited and are exhausted via a stack.
