Launder Segments

Drache manufactures a wide range of launder segments, ranging from small segments for continuous casting, to segments for billet and rolling ingot casting, through to large segments for transfer launders. The choice of the launder cross section is made on the basis of the casting speed of the system to ensure an optimal combination of the turbulence-free flow of metal in the launder and minimised heat loss.

All launder segments are distinguished by their excellent erosion resistance, excellent thermal shock resistance and non-wettability. This means that outstanding endurance can be achieved, combined with minimised maintenance costs and excellent economic efficiency – given the appropriate care and maintenance.

The proven Drache Fused Silica is generally used for casting launders. For transfer launders, we also use SiC-based materials.
