A method of cooling a strand cast in an oscillating mold during continuous casting, wherein the strand during passage through the mold is indirectly cooled in a first zone and guided at all sides and in a final or terminal zone is guided by substantially strip-shaped support surfaces extending essentially in the direction of travel of the strand as well as directly cooled by water guided in a substantially strip-shaped configuration along the strand. The strand, following such indirect cooling and prior to the strip-shaped direct cooling, is directly cooled in an intermediate zone by the application of sprayed water. The mold arrangement used for the performance of the method comprises a first cooling device composed of cooled walls bounding the mold compartment or cavity and a terminal cooling device composed of strip-shaped arranged support surfaces disposed approximately parallel to the lengthwise axis of the strand and strip-shaped cooling water channels located between the support surfaces. The cooling water channels are equipped with water infeed means. Between the first and the terminal cooling devices there are arranged spray nozzles constituting an additional cooling device, the spray pattern of such spray nozzles impinging the hollow mold compartment which is open at all sides between the first cooling device and the last or terminal cooling device.
A method of cooling a strand in an oscillating continuous casting mold during the continuous casting of metals, especially steel, comprising the steps of:
A mold arrangement for continuous casting of metals, comprising a mold, means for oscillating said mold, said mold being composed of a first cooling device formed of cooled walls bounding a hollow mold compartment of the mold through which travels a cast strand in a predetermined direction of travel, a last cooling device formed of substantially strip-shaped arranged support surfaces disposed approximately parallel to the lengthwise axis of the cast strand and equipped with intermediately situated strip-shaped cooling water channels, water infeed means provided for said cooling water channels, and an additional cooling device equipped with spray nozzles arranged between the first cooling device and the last cooling device, said hollow mold compartment being open at all sides at a location between the first cooling device and the last cooling device, said spray nozzles producing a spray pattern which impinges the hollow mold compartment which is open at all sides between the first cooling device and the last cooling device.
A mold arrangement for continuous strand casting of metals, comprising a curved mold composed of a first cooling device formed of cooled walls bounding a curved hollow mold compartment of the mold, a last cooling device formed of substantially strip-shaped arranged support surfaces disposed approximately parallel to the lengthwise axis of the cast strand and equipped with intermediately situated substantially strip-shaped cooling water channels, water infeed means provided for said cooling water channels, an additional cooling device equipped with spray nozzles arranged between the first cooling device and the last cooling device, said spray nozzles producing a spray pattern which impinges the hollow mold compartment which is open at all sides at a location intermediate the first cooling device and the last cooling device, the last cooling device being equipped with plate members associated with both straight sides of the strand, said plate members having cooling water channels which follow the curved arc of the mold and which diverge in the direction of strand movement.
