99.95% Molybdenum Threaded Bar electrode for glass melting
In the demanding environment of electric glass melting, electrode reliability is paramount. Our Molybdenum Threaded Bar is precision-engineered to serve as a critical conductive component (electrode holder or electrode itself) in your glass boosting system. Manufactured from high-purity Molybdenum, these threaded rods maintain structural integrity and electrical conductivity at extreme temperatures exceeding 1600°C (2912°F) in a molten glass environment. They are designed to minimize thermal stress and prevent contamination of the glass melt.
1. Key Features & Advantages
-
High-Temperature Stability: Exceptional resistance to thermal shock and creep at high operating temperatures ensures a longer service life and reduced downtime.
-
Excellent Conductivity: Pure Molybdenum provides superior electrical conductivity, ensuring efficient energy transfer for uniform glass melting.
-
Corrosion Resistance: Specifically formulated to withstand the corrosive nature of molten glass, maintaining dimensional stability.
-
Precision Threading: Our threaded bars are machined with tight tolerances (e.g., UNC, UNF, Metric) for secure connections and easy installation with other electrode components.
-
Custom Manufacturing: Available in various diameters (from 10mm to 100mm+) and custom lengths. We also offer Lanthanated Molybdenum (MLa) options for even better recrystallization temperature and creep strength.
