To provide a carrying device for molten dregs capable of preventing fusion of a carrying conveyor to prolong its life, improving peeling performance of dregs, and extraordinarily improving yield of recovered dregs.

This carrying device is provided with a mold conveyor 10 to carry dregs 34 including molten slag 32 or molten metal 33 discharged from a melting furnace. It is provided with a sorting means 16 to sort the dregs 13 cooled and solidified on the mold conveyor 10, and a return line 17 to return small diameter dregs 20 of about 40 mm or less among the solidified dregs sorted by the sorting means 16 to molds before receiving the molten dregs 34. A layer of small diameter dregs is formed of the small diameter dregs 20 returned on a bottom part of the mold, and molten dregs are dropped over the layer of the small diameter dregs.
