Abstract
Abstract A method of influencing the distribution of different constituents in an electrically conductive liquid, especially a molten metal, wherein an electrical current is conducted through the electrically conductive liquid and at the same time there is formed a magnetic field approximately perpendicular to the direction of flow of the electric current, in order to reduce or increase the effect of the differences in the density of the constituents.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
62 words
A method of influencing the distribution of different constituents in an electrically conductive liquid metal, comprising the steps of: conducting an electric current through the liquid and at the same time forming a magnetic field approximately perpendicular to the direction of flow of the electric current, in order to increase the force of gravity of the constituents of the electrically conductive liquid.
Claim 2
Independent Claim
62 words
A method of influencing the distribution of different constituents in an electrically conductive liquid metal, comprising the steps of: conducting an electric current through the liquid and at the same time forming a magnetic field approximately perpendicular to the direction of flow of the electric current, in order to increase the force of gravity of the constituents of the electrically conductive liquid.
Claim 3
Dependent Claim
33 words
The method as defined in claim 1, wherein: the electric current and the magnetic field are employed for at least doubling the force of gravity of two constituents of the electrically conductive liquid.
Claim 4
Dependent Claim
96 words
The method as defined in claim 1, further including the steps of: producing the electric current by means of an alternating current and the magnetic field by means of a magnetic alternating field; and maintaining the conditions ##EQU6## wherein d represents the largest diagonal of the cross-sectional area disposed essentially perpendicular to the direction of current flow and is in the range of 1 m to 0.1 m, f represents the frequency, μ the permeability of 0.4π10 -6 Vs/Am, and H the electrical conductivity, and is in the range of 0.72 to 2.1 mΩmm 2 .
