The issues of glass production by the float method are considered. The possibilities of reducing the duration of the transition from one type of glass to another when working on one line, increasing the optical performance of float glass, etc. The developed methods allow improving the quality of glass, increasing the output of marketable products and expanding its range.
The optimal mode of drying the silicophosphate gel for the production of glass has been selected. The kinetics of its drying was investigated. Il. 2, bibliography: 6 titles.
The influence of the processes of pouring and spreading of glass melt in a molten bath on the optical performance of float glass is considered. The existing design and technological solutions for leveling temperature gradients in the flow of molten glass, which are one of the main causes of optical distortions, are presented. Bibliography: 7 titles.
The effect of heat treatment on the phase composition, microstructure, and properties of glass-crystalline materials has been investigated. The possibility of obtaining, on the basis of iron-containing glass, glass-crystalline materials of practically the same composition with a wide range of electromagnetic characteristics is shown. Tab. 1, ill. 3, bibliography: 5 titles.
The state and prospects of development of glass container production in Russia are analyzed. Tab. 1.
The possibility of using pyroxene skarns of the Koytash ore field for the production of glass-crystalline materials has been investigated, and the features of crystallization of their melts have been evaluated. The material of the given monomineral pyroxene composition was obtained. Sintered sitalls made on its basis have high acid resistance (99.3%) and bending strength equal to 82 MPa. Il. 4, bibliography: 8 titles.
The analysis of compositions and structural criteria of glasses for microspheres is carried out. A system of equations for modeling the compositions of microspheres is obtained, the limits of applicability of the model are established. A technique for designing glasses for microspheres with low hydrogen permeability and resistant to atmospheric corrosion is proposed. Tab. 3, ill. 3, bibliography: 9 titles.
Work has been carried out to optimize the distribution of the heat load over the burners and to develop a mode that ensures the melting of the charge no further than the second pair of burners in a glass-making furnace. Modes have been worked out that ensure complete combustion of fuel with an optimal amount of excess air. Recommendations for the rational organization of natural gas combustion for this type of furnace are given. Tab. 2, bibliography: 8 titles.
A method is considered, the use of which makes it possible to reduce tin oxides in the low-temperature part of the molten bath, where they are predominantly formed. On the basis of experimental data, a linear multiple regression equation is obtained that describes the effect of a protective gas medium on the reduction potential of the melt bath. Bibliography: 5 titles.
A new program for calculating the recipe for a glass batch has been developed, which makes it possible to accelerate and improve the calculation process, to simulate the change in the composition of glass depending on changes in the chemical composition and the ratio of raw materials, and to quickly recalculate various options many times. Il. 1, bibliography: 3 titles.
