Extending of the glass-making sand base using low-charges technology

Even minor fluctuations (tenths of a percent) in the molten glass of such components as iron and aluminum oxides lead to serious changes in the rheological properties of the melt, heat transfer conditions in the furnace and in the molding units. Non-capital-intensive technologies for enrichment of raw materials are proposed, contributing to the improvement of the quality of glass products. Tab. 1, ill. 1, bibliography: 6 titles.
