    Abstract: The study deals with a new method for heat preparation of machinery for the load acceptance by
volumetric heating of units using coolant flow with a temperature lowered to 1500°C which is regulated by
means of a guide device and a steam generator. The interaction of the coolant flow with the heated object is
described mathematically, thermal and physical properties of the coolant and the design features of the devices
that form the intensity of its heating are revealed. It is substantiated that in order to ensure minimum heat
treatment time for the units with a low-temperature coolant, it is necessary to optimize the flow velocity in the
gap clearance “guide device-unit wall” and the water flow for the formation of a mixed-type coolant.
