The mold comprises two crawler chains rotating in opposite directions and having facing chain strands, the chain strands comprising chain elements having complementary shells defining an ingot mold cavity of round cross-section therebetween. The complementary shells have intermeshing longitudinal edges movable transversely to the direction of rotation relative to each other, and the complementary shells are guided to reduce the round cross-section of successive ones of the mold cavities while being subjected to a compressive stress.
