Abstract

"Method for heat treatment of metals", especially a strip metal coil, which includes the operations of supporting the coil in a closed furnace chamber, applying heat to one end of the coil by direct radiation from an adjacent heat source at said end of the coil, displacing the atmosphere of the furnace on said heat source and said end of the coil, whereby said atmosphere is heated and, preventing overheating of said heat source and said end of the coil, conduct the atmosphere thus heated through the other end of the coil, whereby heat is transferred thereto, return said atmosphere to said heat source, and continue such circulation of said atmosphere until the coil is hot to the desired degree, largely by axially inward heat conduction from the said ends of the coil.
