Description

Technical Field

[0001] The utility model relates to the technical field of furnace parts, and in particular to a cooling device for electrodes of a full-electric glass melting furnace. Background Art

[0002] Glass melting is a very important link in glass production. The output, quality, pass rate, production cost, energy consumption and kiln life of glass are closely related to glass melting. Molybdenum electrodes are often used in glass melting. When in use, the molybdenum electrode is penetrated on the furnace wall of the kiln. It has the advantages of high melting point.

[0003] However, the main disadvantage of molybdenum electrodes is that they are easily oxidized under high temperature conditions in the air, and generally begin to oxidize at 400°C. Therefore, electrodes exposed to the air must be protected during production, otherwise it is easy for the molybdenum electrodes to have high-temperature and easy-to-oxidize characteristics. During the heating process, anti-oxidation measures must be taken for the electrodes. In order to ensure the long-term and stable operation of the molybdenum electrodes, the electrodes exposed to the air in the heating components must be cooled.

[0004] Therefore, a cooling device for electrodes of a full electric melting glass furnace is proposed. Utility Model Content
