An apparatus for refining of an inorganic non-metallic melt and a method for the production of a glass and / or a glass ceramic

摘要

Device for, in particular continuous, refining of an inorganic non-metallic melt, preferably a glass melt, comprising– a refining crucible (3) with an upper side (3c) and an underside (3d), the at least by side walls (10) which, on an inner side (10b) a metallic lining (50, 52) as contact surface is formed, the lining (50, 52) completely the enamel contact surface of the refining crucible (3), and wherein the sequence of the melt in the upper region of the refining crucible (3) is arranged,– at least one heating system (71, 72) to the conductive heating of the lining (50, 52) by means of a current flow in the lining (50, 52), so that the melt by means of the heated lining (50, 52) is capable of being heated, the heating device (71, 72) and the lining (50, 52) via feed lines are connected to one another,– the feed lines the lining (50, 52) via at least one upper connection (60, 61) and at least one lower connection (62, 63) contact in such a way that at least in the lining (50, 52) of the side wall (10), at least in sections, a current flow is generated, which of the upper side (3c) to the underside (3d) or from the bottom (3d) to the upper side (3c) extends.
