I. Pay attention to conducting inspections before use

Generally, before installation and use, it is necessary to test the resistance values of the entire batch of silicon carbide rods and categorize them neatly. This ensures that each silicon carbide rod can operate under ideal conditions. At the same time, the current and voltage conditions should also be checked. If abnormalities are detected in the silicon carbide rods during testing, the cause should be identified and resolved promptly. For example, if the current is too low or too high, it may be due to the resistance value being too small or too large.

II. Handle with care and take protective measures

Silicon carbide rods have stable performance in various aspects, but they are also very fragile and prone to breakage. Therefore, during installation or use, handle them gently and avoid rough actions. During installation, avoid applying force on one side to prevent breakage. If necessary, take protective measures, such as using heat-resistant steel tubes to sleeve the silicon carbide rods. After installation, cover them with thick steel tubes and secure them with protective sleeves.

III. Adjust the voltage as needed

As the resistance value of silicon carbide rods increases after a period of use, it is necessary to raise the voltage to compensate for the loss caused by the increased resistance and ensure stable current. Therefore, the transformer used should have voltage regulation functionality to achieve增壓調節(jié) (voltage boost adjustment). For silicon carbide rods, this can also extend their service life. The above are the main aspects to consider when using silicon carbide rods. Additionally, efforts should be made to reduce the impact of temperature on them to prolong their usability.
