"Method and device for the continuous casting of Sohellguß ^ir

The invention relates to continuous casting, (strand * ■ let) of metals in general, especially steels, _ at high speed, by pulling the mold or eökille one special periodic movement is grantedj it relates both on the method of driving the mold with this be * special periodic motion, as well as those for their visualization certain devices »

During continuous casting, the liquid metal, or in particular the liquid steel, is poured into a casting mold that is open on both indices and cooled by water circulation! this has the task of the metal fully or partially solidify z \ x blank which is cast on a find and a continuous solid or partially solidified at the other end in the form, ^block: is removed.

The increase in the casting speed leads to the metal remaining in the casting mold, so the solidified skin surrounding the block in deai H & k in, da
