Refractory Launder Runners and Troughs are used to transport molten material from furnaces to ladles or casting machines. They are the water "pipe" equivalent for molten metals.

Add challenge. The fire-resistant washing sink has defects. permanent heat flow is unreasonable.

It could be range limited? LIke 10-40 tiles only and no pump to use to make it longer. Also, instead of a "water pump" pumping molten lave into the foundry...it would be an "entry-section runner" being placed at the edge of the lava lake and then you continue with a few trough-sections leading to a foundry entry point.
