Molybdenum Electrode Water Jacket

Molybdenum electrode has good high temperature performance and corrosion resistance, which can withstand the temperature of 2600 ℃ and is a refractory metal. But its high temperature oxidation resistance is poor, at temperatures above 600 ℃increased significantly oxidation, therefore, in order to protect the molybdenum electrode, to prevent quickly oxidized, resulting in electrode fracture, slowing down glass furnace efficiency, so during the operation the electrode should cover with water jacket, otherwise it will affect the normal operation of the furnace and in serious cases will force the melting furnace shutdown.

The main roles of the molybdenum electrode water jacket are as follows:
1. The electrode reliable and stable installed in the furnace refractories can reduce the loss of refractory materials and electrodes;
2. It can cool the part of electrode which is exposed to air below 400 ℃;
3. To prevent the electrode insert parts of refractory materials temperature too high, prevent refractories local damage.

The electrode cooling water jacket includes indirect water cooling protection sleeve, direct water cooling protection sleeve and rapid water cooling protection sleeve. These electrode cooling water jackets are gradually used in the glass electric melting furnace, and the application range is gradually expanded. In actual use, the cooling water jacket has the following advantages: no adverse effect on the surrounding glass liquid and refractory material, minimum absorption of the glass liquid and refractory material, simple electrode cooling water jacket and its cooling system, infrequence maintenance, easy to quickly advance electrode to the kiln.

In order to ensure the normal work of molybdenum electrode, the required cooling water must be softened and water quality should meet the boiler water standards. In addition, in order to save the amount of cooling water should use recycled water system. At the same time, the end of the electrode is connected by screw, so that the electrode can be easily pushed after consumption.
