What’s Really Behind the Electrode Hard Breakage in Submerged Arc Furnace?

As a leading manufacturer of electrode paste, we understand that maintaining electrode stability is critical for furnace operations. Based on extensive industry experience and technical research, the primary causes of electrode hard breakage include:
 
High Ash Content & Poor Storage Conditions – Excessive impurities due to improper storage, combined with low volatile content, can lead to premature sintering or poor sintering, resulting in hard breakage.
 
Frequent Power Outages & Unscheduled Stops – Irregular operations without proper measures during power failures contribute to electrode cracking and sintering delamination.
 
Dust Accumulation Inside Electrode Shells – Prolonged power outages cause thick dust buildup inside the electrode casing. Failure to clean before restarting promotes sintering delamination and hard breakage.
 
Severe Oxidation Due to Prolonged Downtime – If the working section is exposed to air and not buried in charge material, oxidation leads to structural weakening and breakage.
 
Excessive Electrode Length & Overloading – Excessively long electrodes increase tensile stress, while high current density accelerates drying and cracking.
 
Insufficient Cooling – Low air supply in the holding barrel or inadequate water cooling in conductive jaws causes excessive melting of the paste, leading to carbon particle sedimentation and weak sintering.
 
Improper Operation & Overcurrent Conditions – Exceeding the electrode’s current-carrying capacity due to operational errors directly strains its structural integrity.
 
Understanding these factors helps in identifying and mitigating risks in electrode performance. For further technical consultation or high-quality electrode paste solutions, contact our expert team.
