ABSTRACT:
A low-flexure molten metal distribution launder comprises an elongated structural beam which extends over a plurality of casting stations. A plurality of metal level sensors extend downward from the elongated structural beam to measure molten metal levels in underlying metal casting stations. A plurality of spaced U-shaped refractory hangers are supported within the structural beam to form a refractory channel. Refractory liners are received within the refractory hangers to form a molten metal trough within the structural beam. The hangers are spaced from each other and supported from the structural beam in such a way as to allow them to expand and contract relative to the structural beam without subjecting the structural beam to expansion and contraction. The walls of the refractory hangers are air-cooled to reduce heat transfer from the refractory hangers to the structural beam.
