Abstract:
A method for equalizing temperature differences in molten glass in at least one temperature equalization zone that is in the form of side walls, a bottom wall, and a roof that define a channel to transport a glass melt, wherein the equalization zone is located upstream from a tap-off point at which the glass is topped into a mold in a forming machine or the like, said method comprising the steps of: providing resistor heating elements within the interior of each of the temperature equalization zone side walls, bottom wall, and roof, measuring the temperatures of surfaces within the interior of the respective side walls, bottom wall, and roof that are contacted by the resistor heating elements; and controlling the resistor heating elements by an electric controller so that the temperatures of said wall surfaces within the interior of the respective walls are substantially equal to a predetermined tapping temperature of the glass melt.
