TECHNOLOGY  OF  ELECTROHYDROPULSE  MELT  TREATMENT 
IN  A  LADLE  AT A  PREPOURING   STAGE
THIS  TECHNOLOGY  PROVIDES  FOR:
ESSENCE
Pressure pulses of a wide frequency range (0.1 - 100,000 Hz) are supplied to the ladle with the melt by a special-purpose waveguide from the electrodischarge generator of elastic oscillations. This essentially accelerates heat-, mass-transfer, and physicochemical processes at the macro- and micro- levels rendering favorable conditions for its efficient crystallization.

ADVANTAGES

EFFICIENCY

IMPLEMENTATION
At shipbuilding and machine-building enterprises of Ukraine and the CIS for melt treatment in ladles with capacity up to 50 t. Equipment for 350 t ladles is developed.
