There is a problem with the charge ratio, low carbon content, and low slag basicity
1. Section status: The working end of the electrode is severely corroded and bifurcated, and the electrode becomes thinner obviously from top to bottom.
2. Other phenomena: the electrode paste test is normal, the temperature of the electric furnace is low, the output is low, and the electrode is inserted too deep.
3. Reason analysis: the furnace charge lacks carbon, the molten material corrodes the electrode seriously, the overall strength of the thinned electrode is reduced, and it is easy to break when it is impacted by a large external force.
