The quality of electrode slurry sintering can depend on visual observation. How to determine if the electrode sintering is normal? If the surface of the electrode is found to be gray white or dark but not red, then the roasting is good. If it turns red, it is too dry; if it turns black or smokes heavily, it is too soft.
In order to maintain a certain length of the electrode, the electrode paste must balance the sintering speed and consumption speed during the sintering process. If sintering is slow and consumption is fast, insufficient working length of the electrode will result in excessive softness. If sintering is fast and consumption is slow, the electrode will be too dry and prone to hard breakage.
To ensure high-quality electrode sintering, the following requirements must be met:
1. Electrode paste that meets quality standards and block size requirements should be filled at a certain height.
2. The production and welding of electrodes must meet the requirements, and the cooling conditions of the conductive jaw plate and the contact between the electrodes must be good.
3. Try to avoid and shorten the frequency and time of electric furnace power outages as much as possible.
4. Pay attention to the quality of electrode sintering and adjust the cooling conditions of the electrode in a timely manner.
