Due to the unique materials and manufacturing processes used in silicon carbide rods, they possess numerous advantages and do not deform even under extreme temperatures. Given their excellent quality, they can be employed as electric heating elements. However, when using silicon carbide rods, the following aspects should be noted to fully leverage their intended functions.

1. Ensure Proper Inspection Before Use

Before installation and use, it is essential to test the resistance values of the entire batch of silicon carbide rods and categorize them accordingly. This ensures that each rod operates under optimal conditions. Additionally, the current and voltage should be checked. If any abnormalities are detected during testing, the cause should be identified and resolved promptly. For instance, excessively low or high current may indicate resistance values that are too small or too large.

2. Handle with Care and Implement Protective Measures

Although silicon carbide rods exhibit stable performance in various aspects, they are also very fragile and prone to breakage. Therefore, during installation or use, handle them gently and avoid applying excessive force. Avoid unilateral stress during installation to prevent fractures. If necessary, protective measures such as using heat-resistant steel tubes to encase the silicon carbide rods can be implemented. After installation, secure the coarse steel tube and fix it with a protective sleeve.

3. Adjust Voltage as Needed

Over time, the resistance value of silicon carbide rods increases. To maintain a stable current,;it is necessary to raise the voltage to compensate for the loss caused by the increased resistance. Therefore, the transformer used should have voltage regulation functionality to enable增壓調(diào)節(jié) (voltage boosting adjustment). For silicon carbide rods, this also helps extend their service life. The above are the key aspects to consider when using silicon carbide rods. Additionally, efforts should be made to minimize the impact of temperature to prolong their usability.
