IMPROVED METHOD AND INSTALLATION FOR THE PRODUCTION OF FLAT GLASS BY A FLOAT GLASS PROCESS
In order to increase the drive speed (V) of the glass ribbon (8) with the same optical quality as the glass obtained during the production of flat glass by means of floating a glass ribbon (8) on a bath of molten metal (7), all or part of the molten metal (7) located under the glass ribbon (8) is su...

| Zusammenfassung: | In order to increase the drive speed (V) of the glass ribbon (8) with the same optical quality as the glass obtained during the production of flat glass by means of floating a glass ribbon (8) on a bath of molten metal (7), all or part of the molten metal (7) located under the glass ribbon (8) is subjected to a static magnetic field perpendicular to the surface of the glass strip (8) by means of a device (10) with electromagnets and/or permanent magnets for braking the movement of the molten metal (7) or substantially stopping it for at least one portion of the length of an area (Z) of the bath for which the glass satisfies the following relationship: 10-3.5 Pa.m3.s |
