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 chamberinside the strand guide device, in which it is sprayed with a coolant, with the formation of steam. The steam forms at least a steam-air mixture' with sucked-in secondary air, which is sucked out of the cooling chamber by a suction device. In order to reduce the pollutant content of the sucked-in and sucked-off steam-air mixture′ and its emission into the environment, pollutants, primarily dust, located in the steam-air mixture′ are depleted by a separator

A device and method for producing a continuous strip-shaped composite material including a base material of metal, which is unwound in the form of a metal strip by a first coil-unwinding apparatus, and at least one cladding material of metal, which is unwound in the form of a metal strip by a second coil-unwinding apparatus. The metal base and cladding metal strips unwound by the respective coil-unwinding apparatuses are brought together in the hot state of at least 720 degrees Celsius. The unwound base and cladding metal strips brought toward each other and are joined by hot-rolling such that a single continuous strip-shaped composite material is thereby formed by roll cladding such that the composite material includes the base material and the cladding material.
