Sectioning strands comprises reducing the strand in its height before sectioning, sectioning the strand within the height reduced area, moving the strand with a casting speed and performing height reduction in an outflow area

摘要

The method for sectioning strands, comprises: reducing the strand before the sectioning in an area of a posterior section (3) locally in its height, the strand transversely and longitudinally to a transport direction in the height, the strand at a surface temperature of 700-1000[deg] C and a core temperature of 350-550[deg] C, the strand with an individual reduction resulting after each other by a stamp in the height, the strand from above or below in the height, the strand before the stamp, which follows the strand in the transport direction into the height.

The strand reduced in the height at a position has a width of 50-100 mm. An independent claim is included for a device for sectioning strands.
