An installation for the dry transformation of a material microstructure of semi-finished products, especially for dry bainitization, includes a quenching chamber and a microstructure transformation chamber situated downstream from it in the processing flow, in each case the inner space of the two chambers having applied to it excess gas pressure, at least during the respective method step, for the transformation of the material microstructure. Device(s) are provided for maintaining a minimum excess gas pressure acting on the semi-finished product, during the moving of the semi-finished product from the quenching chamber into the microstructure transformation chamber.

A charging frame for accommodating a batch of parts to be quenched, e.g., metal workpieces, has a circumferentially closed peripheral wall which surrounds the batch and thereby forms a flow channel which prevents bypass flows. The charging frame is a part of a quenching device.

Charging frame and quenching device having a charging frame

An installation for the dry transformation of a material structure of semifinished products, particularly for dry bainitization, includes a quenching chamber and heating and/or cooling mechanism for setting the temperature prevailing on the inside of the quenching chamber, wherein the heating and/or cooling mechanism is developed as heating or cooling mechanism of a wall that borders on an inner chamber of the quenching chamber.
