Abstract

Procedure for the accelerated cooling of annealed material after an annealing process inside an annealing furnace, especially rolls inside a bell furnace for annealing, in which a refrigerated shielding gas is introduced into the furnace characterized in that after cooling the annealed material to a temperature, which is a fraction of the annealing temperature, inert liquid gas is introduced into the furnace space.
