Heat treatment equipment - RESISTANCE

DIN EN 10052 provides information on the term of the heat treatment.

It is a series of steps in which the work piece is wholly or partially subjected time-temperature sequences, to change the mechanical properties or the structure. Many steels, for example the heat-resistant steels which are used in power plants, engineering and pipe constructions, receive after welding or deformation the required mechanical properties and quality values only by a following heat treatment.

According to the place of application of the heat treatment a distinction is made between stationary and transportable heat treatment devices. Stationary heat treatment devices are used in workshop production: in an annealing furnace the entire component is heat treated. Transportable heat treatment devices are mostly used in the assembly of prefabricated parts on site. Here are local or partial heat treatment carried out: the heat treatment facilities are adapted to the component in dimension and performance.

For the execution of heat treatment procedure, there are national and international regulations, for example in Germany: FDBR, VdTÜV, DIN, AD, and TRD, in France: CODAP, in Great Britain: BS, in The Netherlands: Stoomwezen and in the United States: ASME and ANSI. The increased requirements for quality and safety increasingly demand exact mathematical calculation of the heat treatment in form of a "thermal finite element analysis", and their graphical computer analysis.
