Raw materials and process

RP 250mm graphite electrode is made of low ash raw material through a series of preparation processes and then machined by high temperature above 3000℃ after graphitization. The product has the characteristics of low resistivity, good electrical conductivity, low ash content, dense and uniform structure, good oxidation resistance and high mechanical strength.

Product classification

1. Ordinary power graphite electrode

This graphite electrode can adapt to very low current density, and is mainly used in ordinary electric furnaces such as steelmaking, silicon smelting, and yellow phosphorus smelting.

2. Oxidation resistant coated graphite electrode

It has an anti-oxidative coating that is both conductive and resistant to high temperature oxidation, thereby reducing electrode consumption during steelmaking.

3. High power graphite electrode

It is mainly used in high-power electric furnaces for steelmaking because it can connect a current density of 18-25a/cm2.

4. Ultra high power graphite electrode

It is mainly used in ultra-high-voltage arc furnaces and can adapt to current densities greater than 25A/cm2.

Main purpose

RP 250mm graphite electrodes are often used in some industrial projects, such as electric arc furnaces, etc., while the demand in other industries is small.

Product inspection

The quality inspection of the electrode shall be carried out by the quality inspection department of Tengrui carbon, and the customer can carry out the acceptance according to the provisions of the standard.

PPackaging
