1. Structural features
Location: The throat is usually set between the melting bath and the working bath of the furnace, which is the necessary route for the flow of glass liquid.
Shape design: The shape of the throat is mostly rectangular, and its width and height are designed according to the specific needs of the furnace and the flow rate of the glass liquid.
2. Functional features
Blocking impurities: The throat can effectively block the scum, foam and unmelted glass liquid in the upper part of the glass liquid, ensuring that only qualified glass liquid enters the next part, thus improving the quality of glass products.
Homogenization of glass liquid: Through the design of throat, the flow path and speed of glass liquid in the furnace can be adjusted to promote the homogenization process of glass liquid and reduce the production of defects such as streaks.
Temperature regulation: After the glass liquid passes through the throat, the temperature will be reduced to a certain extent, which provides more suitable temperature conditions for the subsequent molding process.
3. Material selection
Refractory materials: Throats are usually made of refractory materials with good erosion resistance, such as fused cast AZS blocks, which have excellent resistance to high temperature, scouring and erosion.
4. Design purpose
Improve product quality: By optimizing the structure and material selection of the throat, the impurities and defects in the glass liquid can be reduced, and the overall quality of the glass product can be improved.
Extend the service life of the furnace: Reasonable design of the throat can reduce the erosion of the refractory material by scouring, thus extending the service life of the furnace.
Energy saving and consumption reduction: By adjusting the flow state of glass liquid in the furnace, unnecessary heat loss and energy consumption can be reduced, and the operation efficiency of the furnace can be improved.
