FIELD: metallurgy.
SUBSTANCE: invention refers to the method of control of flow speed and delay of non-ferromagnetic conducting fluids and molten metals using magnetic fields during output from metallurgic tanks, such as melting furnaces. The method is characterized by the following: molten metal flow is directed through closed guide element using at least one stationary magnetic field with constant polarity, at least one stationary magnetic field with alternating polarity or multipolar shifting magnetic field. Magnetic field lines in cross direction all across its section generate tensions in magnetic field in molten metal flow. This results in generation of eddy currents in magnetic field in molten metal flow. They are located radially and axially when stationary magnetic field of constant polarity is used, and axially when stationary alternating magnetic field or shifting electromagnetic field is used. Due to interaction of magnetic fields and eddy currents there generated are forces which reduce molten metal flow speed with simultaneous reduction of turbulence.
EFFECT: development of control method of flow speed and delay of non-ferromagnetic molten metals.
