Gate-type Silicon Carbide Heating Element - Definition
The Gate-Type Silicon Carbide Heating Element creates a stable, uniform transverse radiant heat field at the furnace bottom or sidewalls. It is ideal for high-temperature applications requiring improved heat distribution in lower or lateral furnace zones.
Made from high-purity α-SiC (≥99% SiC) via a high-temperature silicification and recrystallization process, it forms a robust, grain-bonded structure. The heating zone density is approximately 2.65–2.96 g/cm³, with a long-term operating range of 1400–1550 °C and a maximum temperature of 1625 °C.
Due to its structural stability, uniform heating, and flexible installation, this element is commonly found in high-temperature industrial kilns for glass melting, ceramic sintering, and metallurgical heat treatment.

Gate-Type SiC Heating Rod Installation Method
- Inspection: Check for cracks before installation. Ensure no structural issues in the furnace affecting rod placement.
- Installation: Vertical or horizontal installation. Self-supporting at high temp, but furnace must allow free thermal expansion.
- Fixing: Install ceramic chucks/clamps on cold ends, ensure they are outside furnace to prevent overheating.
- Power Connection: Use flat aluminum braid and spring clamps to connect to 110–480V power supply, matching resistance correctly.
- Heating Debugging: Gradually increase to working temp to avoid thermal shock. Enter normal load after stable furnace temp.
- Regular Maintenance: Check aluminum-coated connectors and clamps for looseness or corrosion.
- Note: Installation should be performed by professionals. Contact us for detailed manuals.
Gate-Type Heating Scenario Design Recommendations
Gate-Type SiC Heating Element Configuration & Furnace Matching
- Mounting: Typically installed horizontally via side-wall insertion or suspended mounting.
- Hot Zone Alignment: Ensure the heating zone does not contact furnace walls to prevent ablation.
- Cold Zone Length: Furnace wall thickness + 50–150 mm external connection allowance. This prevents end overheating if too short and avoids an extended non‑heating zone if too long.
- Furnace Port Size: Recommended port diameter is 1.4–1.6 times the cold end diameter. Seal with ceramic fiber gaskets to accommodate thermal expansion and prevent stress damage.
- Spacing Design: Maintain a minimum distance of ≥3× element OD from furnace charge or walls. Center-to-center spacing between adjacent SiC rods should be ≥4× OD. This reduces radiation shielding and improves temperature uniformity.
- Temperature Control System: An intelligent system is recommended for precise regulation, suppressing thermal shock and extending service life.
- Atmosphere: Optimal in oxidizing atmospheres. For reducing, carburizing, or hydrogen-rich conditions, reduce operating temperature or implement protective measures. Contact us for specific application guidance.
