Molybdenum Electrode

Molybdenum electrode made by powder metallurgy technology with pure molybdenum
powder has high melting point, high temperature strength and hardness, good
thermal shock resistance, good electrical conductivity, thermal conductivity
and corrosion resistance. Molybdenum also has a good process suitablility, easy
to carry out pressure processing and mechanical processing. Molybdenum is
resistant to high temperature, corrosion of molten glass, and the corrosion
products do not pollute the glass, so it has been widely used in the glass
melting furnace.

Molybdenum Electrode Types
MoZrO2 Electrode
The electrode may deform due to gravity and glass liquid erosion at high
temperature. We can provide a special electrode enhanced scheme for this case.
A small amount of ZrO2 adding to the molybdenum can greatly enhance the
electrode sag resistance and creep resistance at high temperature.

Coated Electrode
A special kind of silicon material is coated on the surface of the molybdenum
electrode, which can cut off the contact between the air and the electrode,
thereby increasing the service life of the electrode in the oxidizing
atmosphere.

Molybdenum Electrode Specification
The molybdenum electrode is suitable for all kinds of glass furnace except lead
glass, and the highest temperature is 1600℃. We have molybdenum electrode
water jacket, 5K alloy, impeller and other accessories for your choice.

Molybdenum Electrode Application
Glass furnaces are divided into flame heating furnaces and electric melting
furnaces. Electric melting furnaces are mainly divided into all electric-
melting furnaces, forehearth electric boosters and complex furnaces. With the
further improvement of the national energy saving and environmental protection
requirements, the electric melting furnace has began to replace the flame
heating furnace.

Domestically, there are two major systems as follow for the molybdenum
electrode electric melting furnace according to the categories of molten
glassware: soda-lime glass and borosilicate glass. Various specifications of
the plate and rod electrode can meet the requirements for various electric
melting furnace. The electrode has the advantages of less investment, high
energy saving and high yield, corrosion resistance of the glass liquid, uniform
electric load and current density, uniform temperature in the furnace, stable
operation, etc.

There are many titanium rod manufacturers, but we are one of the best choices
for you.
