As a key heating element, the performance and application of molybdenum electrodes in glass furnaces have a profound impact on glass production.
Material characteristics: Molybdenum electrodes are made of high-purity molybdenum materials with a silver-grey metallic luster. Molybdenum has excellent high temperature resistance, oxidation resistance, high conductivity and good corrosion resistance. These characteristics enable molybdenum electrodes to work stably in high temperature environments and extend their service life.
Working principle: In the glass furnace, the molybdenum electrode is used as the negative electrode, oxygen is used as the positive electrode, and the aqueous solution of sodium hydroxide or potassium hydroxide is used as the electrolyte. During the discharge of the battery, molybdenum reacts chemically with oxygen to form molybdenum oxide, which releases energy to heat the glass raw materials.
Application fields: Molybdenum electrodes are widely used in daily glass, optical glass, thermal insulation materials, glass fiber and rare earth industries. Its high high temperature strength and good oxidation resistance enable molybdenum electrodes to withstand high temperatures and maintain a stable heating effect during the glass melting process, thereby improving the production efficiency and quality of the glass.
Layout: In glass kilns, the layout of molybdenum electrodes has an important impact on their performance. The traditional “flat insertion” and “bottom insertion” methods have certain limitations, while the “top insertion” method provides an ideal temperature field for the furnace by adjusting the installation position and electrode shape, improves heating efficiency, and facilitates replacement and maintenance.
Quality assessment: The quality of molybdenum electrodes directly affects the production quality of glass. The uniformity of impurity content and forging density in the electrode are key indicators. Molybdenum electrodes with fewer impurities can reduce glass coloring and transparency problems and improve glass quality.
In summary, molybdenum electrodes in glass kilns play an important role in glass production with their unique material properties and excellent working performance. With the continuous advancement of technology and process optimization, the application of molybdenum electrodes will be more extensive, providing strong support for the development of the glass industry.
