Product Series
Molybdenum Electrode and Water Jacket
Product Introduction
Molybdenum electrodes are prepared by powder metallurgy using high-purity molybdenum powder, and are characterized by their high purity (≥ 99.97%), high melting point, high temperature strength and hardness, high thermal shock resistance, excellent electrical conductivity, thermal conductivity and corrosion resistance, and by their corrosion products not polluting the glass.

Molybdenum zirconium electrodes: To solve the issue of electrode deformation caused by gravity and glass liquid erosion at high temperatures, we can provide a special electrode reinforcement design, which greatly enhances the strength and creep resistance of the electrode at high temperatures by adding a small amount of zirconia to the molybdenum. A further advantage of molybdenum-zirconium electrodes is that they are resistant to corrosion by molten glass, improving the service life of the electrode.
Coated electrode: A special material coated on the surface of the molybdenum electrode, which isolates the contact between the air and the electrode to improve its service life in an oxidizing atmosphere.
Cooling water jacket: The water jacket is essential for installing the molybdenum electrode, and prevents the oxidation and fracture of the electrode in the kiln. ATTL can customize cooling water jackets of various specifications based on your specific requirements. Depending the installation method, the jackets can be divided into double-arm bottom-insert water jackets and single-arm flat-insert water jackets.
ATTL can also customize and produce molybdenum protection plates, nozzles, stirring paddles, GH5K superalloys and other supporting products for kilns to fully meet your production needs.
Product Application
The molybdenum electrodes and cooling water jackets produced by ATTL have been widely used in full electric melting or electric assisted melting furnaces for such products as glass fiber, soda-lime glass, borosilicate glass, medicinal glass, opal glass, foam glass, glass-ceramics, rock wool, and ceramic fibers.
