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

Method and strand guide device for operating a cooling chamber

A method and strand guide for supporting, guiding and cooling casting strands () made of steel, especially preliminary sections () for girders, which are cooled by injected water () and are drawn, serve to prevent cracks, especially surface cracks, from appearing in the microstructure by adapting the cooling conditions of the surface of the strand in the region of the secondary cooling, and serve to prevent undercooling of the strand shell, wherein in order to avoid an undesirable solidification structure on the upper flange edges or in other cross-sectional areas, the cooling and support of the beam blank format are so adapted to the solidification range that cooling and support are provided exclusively where a crater is formed. To this end, the casting strand () is cooled, by guiding the temperature in a specific manner in upper supporting segments (), by means of spray-water jets the width of which at least matches the length of the supporting rollers on longitudinal and transversal sides () of the cross section () of the casting strand, and is decreasingly supported in an analogous manner with respect to the length of the casting path and the cooling state in core areas () of the cross section () of the casting strand on the transversal sides () of said casting strand cross-section () so that cooling occurs exclusively by means of water jets () which are oriented towards said core areas ().

The invention relates to a device for the continuous casting of metals, especially steel, by means of a continuous casting mold () which is mounted in an oscillating frame (). Said oscillating frame can be driven so that it oscillates in the direction of casting (), the course of the oscillation movement and/or the frequency being adjustable. The oscillating frame () is mounted with spring assemblies () arranged symmetrically on both sides of the strand, for guiding and weight compensation. The device is used on a continuous casting mold () with a shaped casting cross-section (), which is mounted in the oscillating frame (). The leaf-spring-mounted oscillating frame () can be operated with the continuous casting mold () in a resonance oscillation method in order to give the preliminary section a better surface.

Device for the continuous casting of metals, especially steel

A method and an installation for producing slabs in a continuous casting plant which includes a strand guiding unit arranged following the casting mold and divided into segments. Each segment is composed of a two-part segment frame whose frame parts are braced together by hydraulic cylinders. Rollers for supporting and conveying the solidifying cast strand are mounted in pairs opposite each other, wherein at least one of these rollers, i.e., the drive roller, is pressed with a defined adjusting force against the cast strand for transmitting the strand conveying forces.
