The match between the glass compositions and the overflow refractory is crucial for glass fusing draw processes. Static experiments and interface analysis were carried out to study the erosion influence of different components of lithium aluminosilicate glass on zircon overflow refractory. The experimental results show that the influence of sodium oxide content on the erosion of zircon overflow refractory is most significant. The higher the sodium oxide content, the lower the zircon breakdown temperature. As the same glass composition, the higher the temperature, the worse the erosion.
The corrosion of high lithium glass on fused cast zirconia corundum bricks were studied through static and dynamic erosion experiments. The surface composition of cast zirconia corundum bricks after corrosion by high-lithium glass liquid in actual production was tested. So as to correctly find the reasons of the corrosion of high-lithium glass on fused cast zirconia corundum bricks in actual production. The research results show that the lithium element in the raw material seriously erodes the fused cast zirconia corundum brick, which is due to the small lithium ionic radius, low valence, and large diffusion coefficient, which makes it easier to react with the acid oxide SiO2 and amphoteric oxide A12O3 in the fused cast zirconia corundum brick, thus causing erosion.
Feeder is a high temperature-running equipment used to cut off molten glass. Therefore,it is necessary to use cooling water and cooling wind to cool the equipment. At the same time, compressed air is required to drive and run feeder. The application history of the feeder was reviewed and the usage of cooling water, cooling air, and compressed air were discussed. It has a reference value for relevant enterprises.

The packaging quality of photoelectric displays glass substrates is crucial for the smooth use of the product on the client side. Poor packaging may cause problems such as fragments, adhesive tapes, and film detachment. This article explores the factors affecting the variation in corner thickness during the packaging process and proposes control measures to mitigate this issue. These measures include replacing rubber with low-friction coefficient polypropylene (PP), utilizing ultrasonic thickness measurement, and incorporating slotting on the baseboard. The implementing methods can enhance the packaging quality of glass substrates, improve customer satisfaction, and enhance market competitiveness.
