Description

technical field [0001] The present disclosure relates to the technical field of substrate glass production, and in particular, to a method, device and storage medium for obtaining the temperature of molten glass. Background technique [0002] In the production process of the substrate glass, the batch material of the substrate glass can be put into the pool furnace, and the batch material is melted at high temperature to form molten glass. Since there are bubbles and inhomogeneous bodies in the formed molten glass, in this way, the molten glass can flow into the In the channel, the glass liquid can be clarified, homogenized, etc. [0003] In the process of processing the molten glass in the channel, in order to ensure the stability of the substrate glass in the production process and the safety of the equipment, an electric heating system can be installed in the channel, so that the electric heating system can flow from the pool furnace according to the glass liquid. The te...

Problems solved by technology

[0003] In the process of processing the molten glass in the channel, in order to ensure the stability of the substrate glass in the production process and the safety of the equipment, an electric heating system can be installed in the channel, so that the electric heating system can flow from the pool furnace according to the glass liquid. The temperature when it flows into the channel makes temperature compensation for each section of the channel. Since the thermocouple can quickly measure the temperature, at present, the thermocouple can be used to detect the temperature of the molten glass flowing into the channel from the pool furnace, so as to realize the temperature compensation of the electric heating system. However, Since the thermocouple wire of the thermocouple is volatile at high temperature, after long-term operation (such as the operation time is greater than or equal to one month), the temperature detected by the thermocouple is lower than the actual temperature when the glass liquid flows into the channel from the pool furnace.
