Do you know why soft breakage accidents occur during the use of electrode paste? Follow Saxin’s insights to understand the reasons behind this issue.
Excessive Volatiles in Electrode Paste: High volatile content in the electrode paste can lead to various issues that contribute to soft breakage during usage.
Improper Thickness of Electrode Shell:
- Too Thin: A thin iron shell is susceptible to breaking under significant external forces, causing folding or leakage of the electrode paste, leading to breakage.
- Too Thick: A thick shell may not fit tightly with the electrode core, resulting in a loose core, which can also cause soft breakage.
Poor Electrode Shell Fabrication or Welding Quality: Defects in the manufacturing or welding of the electrode shell can lead to cracks, causing paste leakage or soft breakage.
Insufficient Load Reduction When Lowering Electrodes: Failing to sufficiently reduce the furnace load when lowering electrodes, or allowing the load to increase too quickly after lowering, can result in soft breakage. This is less of an issue in larger furnaces.
Too Frequent Electrode Lowering: Short intervals between electrode lowering operations or overly long electrodes after lowering can cause soft breakage.
Untimely Addition of Electrode Paste: Adding electrode paste either too early or too late, or at incorrect positions, can also lead to soft breakage.
Oversized Electrode Paste Blocks: Large blocks of electrode paste, if not handled carefully, can get caught on rib plates and remain suspended, potentially causing soft breakage.
Non-standard Operation: Excessive current intensity beyond the electrode’s capacity can lead to soft breakage.
By addressing these issues, the incidence of soft breakage in electrode paste usage can be significantly reduced.
