How to Install Different Shapes of Molybdenum Glass Melting Electrodes?

Molybdenum glass melting electrodes are used to deliver electrical current into glass melts as they can resist to corrosion and oxidation at high temperature. Made of high-purity molybdenum powder and after sintered and forged, electrodes can be formed into different shapes, such as rod and plate. 

The installations of different shapes can be various, and represent their own advantages and disadvantages. 

1.Molybdenum threaded rod

The electrode can be installed from the bottom, broadside, top of the furnace. In the all-electric melting furnace, different combinations are used according to different glass types and furnace types. Commonly used are multiple sets of flat inserts, flat inserts + bottom inserts, bottom inserts + inclined inserts, top inserts + horizontal inserts, top inserts + bottom inserts.

Flat insert: it is the most widely used installation as it is very simple to operate. However, the electrode is easy to become thin and bent, and be corroded by glass melts. 

Vertical installation (bottom insert and inclined insert): it is often used for borosilicate glass. With this installation, the electrode will not be adjusted frequently and the furnace will obtain longer service life. Its advantage is that furnace structure is complicated. In that case, it will be strict for installation. 

Top installation: it is mostly used in glass and various furnace structures, without contact with the lining material, which can increase the service life of the furnace. But it requires high operation accuracy and needs regular inspection.

2. Molybdenum electrode plate

The plate-shaped electrode can be used in melting tank or picking tank. When used for melting, the glass flow is stable and the melting is uniform, which is shallower than the melting pool using rod electrodes. When used in the picking tank, the current density is low and will not cause secondary bubbles. 

Chinatungsten is a professional manufacturer of molybdenum for more than two decades, and molybdenum electrode is one of most outstanding products.
