Whether the part of the throat is made of chrome corundum brick.
Whether chrome corundum bricks are used in the throat, depends mainly on the specific working environment, temperature conditions, and required refractory properties and stability of the throat, as well as on the different types of glass produced by the glass manufacturers.
1.Characteristics of chrome corundum bricks
Chromium corundum brick is a kind of corundum refractory products containing Cr2O3. At high temperature, Cr2O3 and Al2O3 form a continuous solid solution, which makes the high temperature performance of chromium corundum products better than pure corundum products. Chromium corundum bricks have high abrasion resistance, high temperature resistance and stability, and are suitable for high temperature and aggressive environments.
2.Working conditions of the fluid hole
Throat is an important structure in glass pool furnace and other high temperature equipment, and its working environment is usually characterised by high temperature, high flow rate and high erosiveness. Because of the high flow rate and high temperature of the glass liquid in the throat, the erosive effect on the material is serious, so it is necessary to choose high-quality refractory materials to masonry fluid cavern to ensure its long-term stable operation.
3.Applications
According to industry experience and relevant literature, chrome corundum bricks are often used as refractory materials for high-temperature parts such as throat due to their excellent high-temperature performance and stability. Especially at the entrance of the throat, where erosion is more serious, high-performance refractory materials such as zirconium corundum bricks or chromium corundum bricks are usually chosen to build cover bricks in order to extend their service life.
4.The situation of glass production types
Chrome corundum bricks are not suitable for the production of pharmaceutical glass, optical glass or daily glass, as the colour of chrome corundum will be carried into the glass melt, which contains toxic and harmful elements and is not suitable for the more sensitive types of glass production.
5.Conclusion
In summary, it is indeed possible to use chrome corundum bricks in the flow-through portion of the throat, especially if the working environment of the cavern has high refractory material requirements. However, the specific use of chrome corundum bricks should also be determined according to the specific working conditions and design requirements of the throat, as well as the type of glass to be produced. In practice, different combinations of refractory materials may be selected according to the specific conditions of the equipment in order to achieve optimal use.
