How to extend the life of ceramic rods
Although the ceramic rod has a great advantage in performance, it is always a product with a service life, and there is no way to use it without restraint. Therefore, if you want to maximize the value of ceramic rod in a limited time, in addition to standardizing the operation of operators, you can also refer to the following aspects to extend its service life.
1. Surface temperature should not be too high
Even the very durable wear-resistant ceramic rod needs to pay attention to the temperature of the use environment, because its service life will be shortened due to the increasing use temperature. When the temperature of ceramic rod in the furnace exceeds the upper limit, its oxidation speed will be accelerated and its service life will be shortened little by little, so the user should try to avoid making its surface temperature too high.
2. Adjust the voltage in time
If the ceramic rod is oxidized in the process of using, the resistance will increase gradually. In order to maintain the normal temperature of the furnace, the voltage should be increased in time. If the voltage is raised to the highest limit of the used transformer and still can not meet the requirements, you can choose to stop the furnace and change the connection mode of the rod before continuing to use. If the new furnace starts to power on, in order to avoid the occurrence of rod breaking, the voltage should be increased in time. The initial voltage should be half of the rated voltage, and it should be increased slowly after it is normal.
3. Avoid overload
Even if the ceramic rod production process is refined, the product quality can not be used overload. If the ceramic rod breaks or heats unevenly for some reason, and its part shows incandescence or dark red phenomenon, it means that the part of the rod body has begun to age, and the resistance of a section has been too different, so the furnace should be stopped in time for maintenance and rod replacement.
The above is the specific method to extend the service life of ceramic rod, including three aspects: the surface temperature should not be too high, the voltage should be adjusted timely, and the overload should be avoided. In addition, in the process of storage, the ceramic rod also needs to pay attention to moisture-proof to keep the rod dry, so that it can be used longer and play its real value and role.
