ABSTRACT:
For the partial heat treatment of tools which have a work surface and a clamping in region, there is disclosed a furnace, the useful space of which is subdivided into two separate heating spaces by a plate made of heat insulating material whereby the temperature in these heating spaces is lowered by disconnection of the connecting members between the individual heating elements of the all-around heating and the clamping in region of the work tools may be maintained below the conversion temperature of the metal.
