   PATENT CLAIMS:
1. Annealing and hardening furnace, characterized in that the base plates 13, 14, 15 and 17) of the actual hardening space, which is directly coated by combustion gases carried in return, is removed from the insert door (18) or replaced or (for example by inserting bridges ( 19, 20), plate pieces (21, 22), rails (23) and the like) can be raised or inclined to change the direction, cross-section and effect of the fire trains as required.
