Choose a proper electrode grade and electrode diameter according
• Please choose a proper electrode grade and electrode diameter according to the capacity of the electric furnace and the transformer, please refer to Table 1:

Table 1 is the allowed current load of the AC electric furnaces, and as for DC electric furnaces, comsteel furnaces or refinery furnaces, the current load can be properly increased.
• You should consider the following operating factors before choosing the grade and the size of the electrode:
Charging Type
Charging Way
Length of Electrode Pole below Clamp
Distance between Furnace Wall and Electrode
Ratio of Melting Time to Total Heating Time and Tap-Tap Time
Type of Waste Gas Emission System
Oxygen Blast Way and Oxygen Blast Amount
Steel Grade, Flow, Period and Balance of Working Procedures, etc.
