# H-Type SiC Heating Elements

## H-Type SiC Heater Description

H-type silicon carbide heating element (also called SiC rod) is a non-metal electric heating element made from high-purity green hexagonal silicon carbide, sintered at 2200℃ through high-temperature silicification and recrystallization, built for high-temp furnaces and industrial heating. 

Its H-type design, paired with aluminum braids and H-type clamps (M-type clips), ensures solid conductivity and secure fixation, making it ideal for oxidizing atmospheres that reach up to 1625°C (2957°F) with a 2000-hour continuous lifespan.

It offers resistance to extreme heat, oxidation, and corrosion, heats up quickly, retains its shape, and is easy to install and maintain, making it a go-to choice for ceramics, semiconductors, glass, metallurgy, and various research applications. Paired with an automated power supply, it delivers precise, constant temperature control or automatically adjusts according to process curves.

## H Type SiC Rods Ordering Information

When ordering H-type silicon carbide heating elements, please provide the following parameters:

- **Diameter**: Cold end/hot end diameter (8-65mm)

- **Length**: Hot zone (HZ), cold zone (CZ), total length

- **Resistance**: As per circuit design

- **Example**: H-type SiC rod, diameter 14/25mm, hot zone length 400mm, cold zone length 250mm, resistance 8Ω

*Note*: Custom specs are available to ensure perfect compatibility with furnace designs.

## H Type SiC Rods Connection Method

- **Installation Position**: The H-type clamp (M-type clip) with aluminum braid is fixed to the SiC rod’s cold end at its outermost point, ensuring tight contact with the aluminum coating.

- **Connection Method**:

Place the aluminum braid on the SiC rod’s cold-end aluminum coating.

- Secure the aluminum braid around the cold end with the H-type stainless steel clamp (M-type clip) using screws.

- Verify that the clamp’s diameter marking (8-65mm) matches the diameter of the SiC rod.

- Connect to the power source, ensuring connection end voltage <0.01V for solid electrical contact.

- After 2-3 hours of furnace operation, re-tighten screws to address thermal relaxation.

- *Note*:

- Avoid over-compression during installation to prevent damage to the SiC rod.

- Keep cold end temperature <300℃ to avoid overheating and connection failure.

- Use an SCR voltage regulator (for precise current control) to extend the element’s lifespan.

## H Type SiC Heater Installation Method

To ensure the performance and safety of H-type silicon carbide heating elements, follow these steps:

- **Inspect Components**: Check that the SiC rod, H-type clamp (M-type clip), and aluminum braid are undamaged, and verify that the diameter markings match the element.

- **Secure Cold End**: Place the aluminum braid on the aluminum coating of the cold end, using the H-type clamp to secure it with screws.

- **Vertical/Horizontal Installation**: Install the SiC rod vertically or horizontally per furnace design, ensuring no mechanical stress and keeping clearance (≥3 times hot end diameter) from furnace walls.

- **Power Connection**: Connect the power source via the aluminum braid, ensuring good contact and connection end voltage <0.01V.

- **Initial Operation**: After 2-3 hours of furnace operation, re-tighten clamp screws to address thermal relaxation.

- **Maintenance Check**: Regularly check clamp and screw tightness to prevent loosening or damage from overheating.

- *Note*: Installation must be performed by professionals, avoiding striking or over-compressing the SiC rod to prevent damage. For detailed guidance, please get in touch with us.

## H Type SiC Elements Design Recommendations

- **Diameter Matching**: Choose an H-type clamp matching the cold end diameter (8-65mm), verifying marked numbers.

- **Cold End Length**: Design cold end length (Le) based on furnace depth, keeping cold end temperature <300℃.

- **Resistance Matching**: Select appropriate resistance based on circuit design to avoid overloading or underloading.

- **Installation Space**: Keep clearance (≥3 times hot end diameter) from furnace walls/bottom to prevent localized overheating.

- **Temperature Control**: Use an SCR voltage regulator (for precise current control) to extend the element’s lifespan.

- **Regular Maintenance**: Check clamp and screw tightness after 2-3 hours of initial operation to prevent loosening or corrosion that may affect performance.
