Glass Melting Electrodes & Water Jacket

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.

Material Introduction

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.

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.

Product Specification:

The molybdenum electrode is suitable for all kinds of glass furnace except lead glass, and the highest temperature is 1600℃. ATTL can provide design, installation, transformation of a full set of application technology services to ensure the smooth operation of the customer. We have molybdenum electrode water jacket, 5K alloy, impeller and other accessories for your choice.

Our Advantages:

In China, we took the lead in the research on the success of molybdenum electrode and application technology, used for glass fiber drawing furnace, glass furnace forehearth, to replace expensive platinum electrode. This technique won the 1981 third prize of national invention, and has been popularized and applied in the whole country.

Self-development and production of all electric glass melting furnace molybdenum electrode and corresponding cooling system equipment has prospered and been widely applied in the domestic and foreign well-known glass enterprises and companies. We have got the trust and praise of our customers.
