Distribution of fresh melted glassmelt in glass ribbon

The conditions for the distribution of the indicator - yttrium oxide, introduced with the charge, over the width and thickness of the glass ribbon during its production on the metal melt are considered. It is shown that in the thickness of the strip, the marked newly welded molten glass is located in the form of luminescent layers, the number of which increases with time up to a uniform distribution of the indicator in the strip. It was found that the decisive role in the distribution of the labeled molten glass in the glass ribbon is played by the transverse convection of the molten glass. Tab. 2, bibliography: 6 titles.
