Recommended current load of electrode

A range of current load in the table is only for the ac arc furnace. When used for dc arc furnace and refining furnace, electric current can be appropriately increased.

Remarks:

 1:When actual use , should be based on specific furnace condition to choose the specifications and grades of graphite electrode. The primary factor is the maximum current intensity, but also considers other factors, such as the characteristics of the electric furnace itself, the type of furnace charge, smelting time, oxygen blowing and mechanical requirements and steelmaking process system, and so on.

  2:Usually, most grades of graphite electrodes physical and chemical indicators have been standardized. But in use process, sometimes also need to consider the impact of temperature on some indicators. 

The matters needing attention when using graphite electrode:

    1: According to the electric furnace transformer capacity and load, choose appropriate grade and diameter of the electrode

   2: Electric furnace charging, large burden should be placed in the bottom of the furnace, so as not to burden fall fractured electrode. In the process of smelting, should avoid a lot of lime and other non-conductive objects gathered just below the electrode, otherwise it will affect the electrode electricity, even lead electrodes break.

   3: Pay attention to the position of furnace cover. If the furnaces cover deviation, the electrode will touch the furnace cover if the furnace cover in lifting, and cause electrode damage

   4: When connecting the electrodes, if there is joint bolt defect and should be replaced before connecting filled
   5: after connected the graphite electrode, you should to  check the attach surface, if find gap, you must to find out the cause. And You can use it until the gap disappeared.

   6: The electrode must be vertical use , It is forbidden to tilt

   7: Electrode holder should be sandwiched between the up and down of the top electrode parts between two lines. Do not clip in line (joint hole) and in the middle of the electrode, electrode column break easily otherwise.
   8:Because of different manufacturers of raw materials and production processes may differ, their physical and chemical properties of the electrodes also have some differences, it is recommended that not to swop use joints and electrodes of different manufacturers
