Abstract (en)

[origin: EP2656945A1] The refractory casting tube (2) comprises a tubular top part (3) and an immersible, flattened bottom part (5) dipped into a molten metal in an inner mould space (6) during the casting. A refractory deflection element is integrated in a funnel-shaped or similarly shaped inlet (4) of the top part, and is shaped such that a fluid-dynamic dissipation is generated on the molten metal during casting in the inlet. The casting tube is directly supported to a mold (1) in its top part. The inlet is formed in a form of a cone, a pot or other shape. The space of the inlet is totally or partly flattened. The refractory casting tube (2) comprises a tubular top part (3) and an immersible, flattened bottom part (5) dipped into a molten metal in an inner mould space (6) during the casting. A refractory deflection element is integrated in a funnel-shaped or similarly shaped inlet (4) of the top part, and is shaped such that a fluid-dynamic dissipation is generated on the molten metal during casting in the inlet. The casting tube is directly supported to a mold in its top part. The inlet is formed in a shape of a cone, a pot or other shape. The inner space of the inlet is totally or partly flattened. The inlet includes an insert body with a support flange and a closed-end projection having an outlet. The bottom part of the tube has a length that is 1/3 of mold length, is continuously formed in a tubular shape, and comprises side longitudinal slots in its bottom portion. An independent claim is included for a refractory cover plate.
