blooming mill

The ends of the blooming mill and open hearth furnace buildings were crushed in by the force of the flood.

Fifty yards from the base was the blooming-mill, where the metal was being rolled into great oblong shapes called "blooms."

I walked the four hundred yards to the open-hearth, and noticed clearly for the first time the yard of the blooming-mill.

Trainloads of them pass daily out of the pit to the blooming-mill, to catch their first transformation.
