Modern Techniques in the Direction of the Global Heat Treatments Applied to Largest Devices

The paper includes aspects specific to the design and the direction of the global heat treatments (GHT) applied to the largest static devices. There are studied the combustion processes specific to the GHT in the variant of heating with flame inside the largest structure. The elaborated calculus algorithm is finalized under the form of combustion diagram and is the base of the recommendations concerning the correct combustion leading, specific to the periods of heating and maintenance of the device to the temperature of heat treatment. Also, there are presented the principles, the conditions and the working algorithms of which application assure optimal conditions from the technological and economic point of view for the direction of the stress relaxation heat treatment applied to a largest device in welded structure.
