Why  Should You Select Appropriate Graphite Electrodes For Acr Furnaces

importance of graphite electrodes selection

Because it’s very important to your acr furnaces and even affect the life of the arc furnaces.

Electrode oxidation, sublimation, dissolution, spalling and breaking are all related to the cost of EAF steelmaking.

Proper graphite electrode selection, use and maintenance can effectively reduce electrode consumption.
