UHP grade graphite electrode

Short Description:

The graphite electrodes are components of the roof structure of the furnaces and are bring together into columns and attached to the roof. Depending on the manufacturer, the electrodes can be as small as 3 inches in diameter, or as large as 30 inches. This will also be dependent on the size of the furnace and the volume of material requiring melting. Graphite electrode supplier provides best quality Graphite Electrodes.  Quality of Graphite Electrode:  Electric low resistivity Good electrica...

The graphite electrodes are components of the roof structure of the furnaces and are bring together into columns and attached to the roof. Depending on the manufacturer, the electrodes can be as small as 3 inches in diameter, or as large as 30 inches. This will also be dependent on the size of the furnace and the volume of material requiring melting. Graphite electrode supplier provides best quality Graphite Electrodes. 

Quality of Graphite Electrode: 

  • Electric low resistivity
  • Good electrical and thermal conductivity
  • High oxidation resistance
  • Higher thermal resistance and mechanical shock
  • High mechanical strength
  • High precision machining

Application :

Graphite electrodes are used primarily in electric arc furnace steel manufacturing. Graphite electrode can provide high levels of electrical conductivity and capability of sustaining the extremely high levels of generated heat Graphite electrodes are also used in the refinement of steel and similar melting process.

Carbon. graphite electrodes are also used in gouging operations such as in the forming of a bevel or groove removing defects in castings or weldments by an arc or gas process,arc gouging removes material by melting it with the heat of an arc struck between a carbon. Graphite electrode and the base metal. Compressed air or nitrogen simultaneously blows the molten metal away.
