FREMGANGSMAATE FOR JUSTERING TIL NIVAAET AV KONTAKTLINJEN MELLOM DEN FRIE OVERFLATEN AV METALLET OG STOEPEFORMEN VED DEN VERTIKALE STOEPING AV PRODUKTER AV ET HVILKET SOM HELST TVERRSNITT.

摘要

The invention relates to a method for regulating the level of the line of contact of the free surface of the metal with the vertical coulee ingot in a continuous products of any cross-section, in which there is applied to the liquid metal during solidification, by means of an electrical circuit, surrounding the ingot, a magnetic field of variable intensity and direction substantially parallel to the axis of the ingot and the field as a function of the level desired). / p & & p & it is characterized in that one module to the field applied to at least a fraction of the periphery of the metal or by modifying the distance circuit - ingot, either by changing the height position of the circuit, or by varying the shape of the profile of the circuit. / p & & p & the invention relates to the circuit can also make it possible to apply the invention. / p & & p & this makes it possible to reduce the thickness of the cortical layer, to refine the grain and regularize the skin of the products cowls.
