Molybdenum Rod Electrode

Molybdenum rod electrode includes horizontal rod electrode and vertical rod electrode. The horizontal rod electrode usually used in the electric furnace and intallated and the electrodes are arranged on the two sides of the cell wall, so as to take care of the need of the melting process and the distance of the vertical electrode. The resistance is also much larger, which improves the low-voltage and high-current in a certain extent Operating status. Horizontal bar electrode diameter is generally between 30 ~ 50mm, the insertion depth of about 500 ~ 700mm, can be inserted in the furnace after the start (that is, thermal installation).

The advantages of the vertical electrode are: the conductive length, the successful operation of the electrode almost no maintenance, the use of high efficiency. The electrode in the furnace of the rational allocation and power matching, can greatly improve the melting quality and the expected amount of material. Large-scale furnace and high-resistance glass has a good adaptability, the electrode can be added once the fracture. The main disadvantage of the vertical installation of the electrode is: when the oxidation prevention measures are not, the electrode is easy to damage and replace the electrode is very difficult. If the bottom of the erosion is serious, there will be leakage through the risk of leakage, should strengthen the protective measures.

The main disadvantage of the vertical installation of the electrode is: when the oxidation prevention measures are not, the electrode is easy to damage and replace the electrode is very difficult. If the bottom of the erosion is serious, there will be leakage through the risk of leakage, should strengthen the protective measures. Because of this, vertical installation electrodes are not used on all-electric melting furnaces, and are widely used in electric kilns since the latter is close to the bottom of the tank and the heat is concentrated in the depth of the glass bath.

Vertical electrode use should pay attention to:
1.The level of holes on the electrode hole and the vertical hole electrode hole has strict requirements;
2.On the water jacket and the relative position of the brick must be taken into account to determine the temperature of the furnace after the expansion;
3.Metal fixture strength and processing accuracy and insulation requirements are higher;
4.To take the risk of leakage of the bottom of the furnace.
