Different grades, different performance.

It mainly depends on the power, whether it is ordinary RP, high HP, or ultra-high UHP.

Specifically, it will involve: density, ash, resistivity, flexural strength, elastic modulus, etc.

Classification of graphite electrodes:

1. Ordinary power graphite electrode.

It is permissible to use the current density below.

The 17a cm2 graphite electrode is mainly used in ordinary power electric furnaces for steelmaking, silicon, yellow phosphorus, etc.

2. Anti-oxidation coated graphite electrode.

2 graphite electrodes. It is mainly used in ultra-high power steelmaking electric arc furnaces.

(1) Used in electric arc furnace steelmaking, electric furnace steelmaking is the main user of graphite electrode. China's electric furnace steel production accounts for about 18% of crude steel, and graphite electrodes for steelmaking account for 70% and 80% of the total consumption of graphite electrodes. Electric furnace steelmaking uses graphite electrodes to introduce an electric current into the furnace, and uses a high-temperature heat source generated by the arc between the electrode and the charge for melting.

2) Used in submerged thermal electric furnace. Submerged arc furnaces are mainly used for the production of industrial silicon and yellow phosphorus. It is characterized by the fact that the lower part of the conductive electrode is embedded in the charge, forming an electric arc in the material layer and heating the charge using the thermal energy generated by the charge's own resistance.

Among them, the submerged arc furnace with high current density needs graphite electrodes, such as about 100kg of graphite electrodes for every 1t of silicon produced, and about 40kg of graphite electrodes for every 1t of yellow phosphorus produced. (3) The graphitization furnace, glass melting furnace, and electric furnace for the production of silicon carbide are all resistance furnaces, and the materials in the furnace are both heating resistors and heated objects. Conductive graphite electrodes are usually embedded in the wall of the furnace head at the end of the resistance furnace for intermittent consumption of the graphite electrodes.

4) It is used to prepare special-shaped graphite products. Electrode blanks are also used to process various special-shaped graphite products, such as crucibles, molds, boats, heaters, etc. For example, in the glass industry, for every 1t of melt tube produced, 10t of graphite electrode blank is required; For every 1t of quartz bricks produced, 100kg of graphite electrode blanks are consumed.

Uses and properties of graphite electrodes:

1. It is used in arc steelmaking furnace.

Graphite electrodes for steelmaking account for about 70 80 of the total amount of graphite electrodes.

2) Used in submerged thermal electric furnace.

The graphite electrode ore thermoelectric furnace is mainly used for the production of ferroalloys, pure silicon, yellow phosphorus, matte copper and calcium carbide, etc., which is characterized by the lower part of the conductive electrode buried in the charge, so in addition to the heat generated by the arc between the electric plate and the charge, the heat is also generated by the resistance of the charge when the current passes through the charge. Each ton of silicon needs to consume about 150kg of graphite electrode, and each ton of yellow phosphorus needs to consume about 40kg of graphite electrode.

3. It is used in resistance furnace.

The graphitization furnace used for the production of graphite products, the melting furnace for melting glass and the electric furnace for the production of silicon carbide are all resistance furnaces, and the materials contained in the furnace are not only heating resistance, but also the object of heating. Normally, the graphite electrode for electrical conductivity is inserted into the furnace wall at the end of the hearth, so the conductive electrode is not continuously consumed.

4. For processing.

A large number of graphite electrode blanks are also used to process into various crucibles, graphite boats, hot die casting molds and vacuum electric furnace heating elements and other special-shaped products. It should be noted that there are three kinds of graphite material synthetic materials at high temperature, including graphite electrode, graphite mold and graphite crucible, and the graphite in these three materials is easy to undergo oxidative combustion reaction at high temperature, resulting in an increase in the porosity of the glue carbon layer on the surface of the material and a loose structure, which affects the service life.
