Calculation Method of Graphite Electrode Consumption of ...
Calculation Method of Graphite Electrode Consumption of Electric Arc Furnace Electrode The graphite electrode consumption in electric furnaces is generally considered to be the third largest in the cost of molten steel after scrap steel and electrical energy. In Europe, the consumption range is 3 to 7 kg / t (crude steel).
Graphite electrode for electric arc furnace - Rongxing Group
The steel-making electric arc furnace uses graphite electrodes as conductive materials and transfers heat energy to the charge through arc discharge to melt the charge. An ordinary electric arc furnace has three electrodes, each of which consists of 3 to 4 electrodes connected together with a tapered joint.
OEM graphite electrodes consumption for arc furnaces
The electrodes come with a wide range of sizes, but diameter of 600mm and 700mm high performance. UHP graphite electrode is often used for ultra high power electric arc furnaces (EAF) with current density greater than 25 A/cm2. The length of EAF graphite electrodes can be up to 2900mm. They are usually packed with pre-set graphite nipple, which ...
Factors Affecting the Consumption of Graphite Electrodes in ...
According to relevant data, with the continuous improvement of ultra-high power electric arc furnaces and related technologies, the electrode consumption dropped from 6.5 kg/t to 1.2 kg/t from 1965 to 2000. The power consumption is reduced from 630 kW. h/t to 290 kW. h/t and the tapping time is reduced from 180 min to 40 min.
