Method and apparatus for filling a continuous casting mould when casting on a strand

摘要

For the automatic filling of a continuous casting mould, the melt is, during the casting-on operation, passed portion-by-portion into the mould by intermittent opening of the bottom outlet of a launder or a tundish. In order to be able to flush away a blockage of the bottom outlet opening quickly, it is proposed to increase the opening set point of the bottom outlet opening for one casting portion (II) relative to the opening set point (K1) of the preceding casting portion (I) unless the increase in the molten metal level (Hactual) due to the preceding casting portion (I) reaches a specifiable value. <IMAGE>
