Products of a cylindrical shape of dark gray or black color made of artificial graphite with a specific electrical resistance value of not more than 5.5 μΩm * m. The main basic element of graphite electrodes is carbon.
The starting materials for the production of graphite electrodes are petroleum coke, coal tar pitch and other carbonaceous materials.
The graphite electrode serves as a source for introducing an electric arc into the furnace space for melting the charge metal charge and heating liquid steel to a temperature of no more than 1750 °C.
In terms of appearance and surface parameters, the electrodes must meet the following requirements:
When shipped, the electrodes are formed into transport packages, the packaging is developed by the manufacturer of the products and must ensure the safety of the cargo during transportation.
The electrodes must be supplied complete with nipples (one nipple per electrode). During storage, the electrodes must be in conditions that exclude moisture and loose materials from getting on it. Do not store electrodes without packaging.
