uhp 600mm graphite electrode with low resistivity for lf furnace

Ulanqab graphite electrode is very important in our current life. The emergence of uhp 600mm graphite electrode with low resistivity for lf furnace has brought great convenience to our lives, so we are using Ulanqab graphite electrode What are the precautions for life?

1. The greater the amount of current applied to the graphite electrode, the higher the surface temperature of the graphite electrode. It is recommended to use the smallest possible surface load density (power). Please note that the values recorded at the cold end of the uhp 600mm graphite electrode with low resistivity for lf furnace are the current and voltage at 1000°C in the air, which are inconsistent with practical applications. Under normal conditions, the apparent power of the graphite electrode is obtained from the relationship between the furnace temperature and the surface temperature of the graphite electrode. It is recommended to use the uhp 600mm graphite electrode with low resistivity for lf furnace and the apparent power of 1/2-1/3 of the density limit. (W/ cm2), high temperature resistant graphite electrode.

2. The graphite electrodes can be connected in parallel as much as possible. If the resistance values of the graphite electrodes are different, the load of the uhp 600mm graphite electrode with low resistivity for lf furnace with high resistance in series is concentrated, which will cause the resistance of a certain graphite electrode to increase rapidly, and the life will be shortened.

3. After the graphite electrode is heated in the air, a dense silicon oxide film is formed on the surface, which forms an anti-oxidation maintenance film, which has the effect of extending the life. In recent years, various coatings have been developed to prevent the graphite electrode from cracking and used in furnaces with various gases. Lubricate uhp 600mm graphite electrode with low resistivity for lf furnace.

4. The temperature distribution characteristics of the graphite electrode. The reflection specification at the time of new shipment is that the useful fever length is within Δ60℃. Of course, the temperature distribution will become larger as it ages and can reach 200℃. The detailed temperature distribution changes are also different due to differences in furnace atmosphere and operating conditions.

5. When continuing to use the graphite electrode, I hope to add resistance slowly to maintain a long life.

6. The higher the operating temperature, the shorter the life of uhp 600mm graphite electrode with low resistivity for lf furnace. Therefore, when the furnace temperature exceeds 1400℃, the oxidation rate will accelerate and the life will be shortened. Please be careful not to let uhp 600mm graphite electrode with low during use. The surface temperature of the resistivity for lf furnace is too high.
