Straight (ED type) SiC Heating Elements

CVSIC ED Type SiC Rods Description

CVSIC Straight Silicon Carbide (SiC) Heating Elements (ED/Straight/ROD/RR/GD Types) are crafted from high-purity, high-density green silicon carbide using a high-temperature silicon recrystallization process with a hot zone density of up to 2.8g/cm³ and a maximum operating temperature of 1650℃. The uniform diameter design ensures high mechanical strength, oxidation resistance, and corrosion resistance, making it ideal for high-temperature and harsh environments. Perfect for box furnaces, laboratory furnaces, tunnel furnaces, and more, these elements provide a budget-friendly and high-performance heating solution.

ED Type SiC Heater Connection Method

• Contact Surface Design: The cold end is coated with aluminum for low-resistance contact, ensuring efficient conductivity.
• Electrical Connection: Secured with flat aluminum braid and spring clips, supporting single or double-end connections for stable installation.
• Note: Select the appropriate voltage (110-480V) and connection method (series, parallel, or star/delta) based on furnace power and temperature requirements. Use an SCR voltage regulator (for precise temperature control) to extend lifespan.

ED Type SiC Heater Installation Method

To ensure the performance and safety of Straight Silicon Carbide Heating Elements, follow these steps:

1. Inspect Element: Before installation, ensure the element is free of cracks or damage.
2. Installation Type: Supports vertical or horizontal installation; high-temperature rigidity eliminates the need for additional support.
3. Fixing Device: Use ceramic chucks or dedicated clamping devices to avoid direct metal contact.
4. Power Connection: Hook up to a 110-480V power supply with flat aluminum braid and spring clips to match resistance properly.
5. Ventilation: Maintain good ventilation in the installation area to prevent localized overheating.
6. Preheating: Gradually increase power during first use to avoid thermal shock.
7. Regular Maintenance: Check aluminum coating connections and clamps for looseness or corrosion.

Note: Professionals should perform the installation. Contact us for detailed guidance.

ED Type SiC Heater Design Recommendations

To optimize the performance of Straight Silicon Carbide Heating Elements, follow these suggestions:

• Hot Zone Length: Match the hot zone length to the furnace width to avoid insertion into the furnace wall, preventing ablation.
• Cold Zone Length: Cold zone length should equal furnace wall thickness plus 50-150mm extension for accessory connection.
• Furnace Aperture: The furnace aperture should be 1.4-1.6 times the cold zone diameter to allow free expansion and prevent cracking.
• Spacing Design: Maintain ≥3 times the outer diameter between the element and material/furnace wall and ≥4 times the outer diameter for center-to-center spacing to optimize heat distribution.
• Temperature Control System: Use a PID controller for precise temperature control to extend the element’s lifespan.
• Atmosphere Selection: Adjust the maximum operating temperature according to the atmosphere type (e.g., oxidizing or reducing); consult our technical team for optimal configuration.
