FIELD: technological processes.
SUBSTANCE: in conventional methods of cleaning the surface of workpieces using steam or hot water during automated production, the temperature of the workpieces can be varied such that due to thermal expansion dimensions exceed tolerances, and subsequent assembly or processing is possible only after stage of bringing to a certain temperature. In compliance with this invention, it is proposed to move steam or hot water jet for cleaning to be scanned over billet surface and to perform this method under reduced pressure, that residues of condensed steam or water available on surface are evaporated, at least partially, and at that heat is again extracted from workpiece, supplied by means of steam or hot water. Preferably, the cleaned surface is simultaneously dried.
EFFECT: method and device for cleaning metal billets are proposed.
