Glass Electric Boosting Molybdenum Electrodes
What Are Molybdenum Electrodes?
Molybdenum electrodes are created via balancing pressing, forging, rolling, planing, and milling after being sinterized in a medium frequency furnace. It serves as a piece of the glass fiber kiln's electro-heating system.
Molybdenum is the primary material in the molybdenum electrode and is produced using powder metallurgy. To ensure the quality of the glass and the longevity of the electrode, the widely used molybdenum electrode has a density more than 10.15g/cm3 and contains 99.95% of the components. Molybdenum electrodes are frequently employed, and their sizes range from 20 to 152.4 mm in diameter and up to 1500 mm in length. The present molybdenum electrode may effectively minimize environmental pollution by substituting for the original heavy oil and gas energy and improve the quality of glass.
