FIELD: metallurgy.
SUBSTANCE: invention relates to metallurgy field and to foundry. For achievement of technical result it is implemented heating of shot up to austenisation temperature and following tempering for one cycle in fluid bed, herewith it is applied bainitic hardening, temperature of which is adjusted in the range of 150-500°C depending on purpose of shot. Additional in cycle of thermal treatment it is excluded tempering process.
EFFECT: simplification of technological cycle for receiving by thermal treatment of cast metallic shot, reduction of thermal treatment time, reduction of power inputs and conditioning of metallic shot.
