A method and system for monitoring the liquid level of molten glass in a furnace during substrate glass preparation.

This invention discloses a method and system for monitoring the liquid glass level in a furnace during substrate glass preparation, belonging to the field of substrate glass manufacturing technology. It solves the technical problem that existing technologies cannot achieve real-time monitoring and adjustment of the liquid glass level in a substrate glass furnace to ensure its stability. The method involves collecting weighing data of glass powder and substrate glass, and calculating the theoretical height of the liquid glass level in the furnace. Subsequently, a glass volume conversion coefficient is set, and the actual liquid glass level is manually measured. The theoretical and actual liquid glass levels are compared to correct the volume conversion coefficients for melting glass powder and substrate glass. By comparing the difference between the theoretical and target liquid glass levels, the feeding frequency of the feeding system is adjusted, thereby achieving adjustment and stability of the liquid glass level in the substrate glass furnace.
