The installation including a mold (2) with cooled walls and a top melt receiver (5) has an annular chamber (9) which surrounds the pouring pipe (81) from the melt receiver, and can be supplied with gas at a variable pressure. The gas pressure in the annular chamber (9) is controlled in such a way that the annular free melt surface (12) is maintained at a constant level. |
