5. FAQS

1. Thermal Shock Resistance
Q: How resistant are your elements to rapid temperature changes or thermal shock?
A: They have good thermal shock resistance, but rapid quenching or cooling with forced air should be avoided. Always follow recommended heating and cooling rates to maximize lifespan.

2. Cleaning and Maintenance
Q: Can damaged or oxidized rods be cleaned or repaired for further use?
A: No, they cannot be repaired or effectively cleaned. Once the material is oxidized or degraded, the process is irreversible. The element must be replaced to restore furnace performance.

3. Comparison to Molybdenum Disilicide
Q: What are the key advantages of silicon carbide rods over molybdenum disilicide (MoSi2) elements?
A: Key advantages include higher mechanical strength at room temperature, better resistance to thermal shock, and often a lower initial cost for applications within their temperature range.

4. Effect of Surface Load Density
Q: What is surface load density, and why is it important?
A: It's the power dissipated per unit of surface area (W/cm²). Exceeding the recommended load will overstress the element, leading to localized overheating and drastically reduced life.

5. Warranty Coverage
Q: Does your product warranty cover normal resistance increase over time?
A: Our warranty covers manufacturing defects but does not cover the normal and expected gradual increase in electrical resistance that occurs as part of the element's natural aging process.
