method and device for the manufacture of moulded stahlbloecken down with clean surface

摘要

During casting, 7-30 Nem3 of rinsing gas/sec.cm of ingot circumference is passed from the mould foot into the melt in an annular zone whose width corresponds to the peripheral layer of the ingot. Specifically, on the mould panel is an annular box in which a jet tube is embedded with fireproof material. The tube inlet is through the mould wall.
