W-Type SiC Heating Elements

W-Type SiC Elements Description

CVSIC W-Type Silicon Carbide (SiC) Heating Element (M-Type) is crafted from high-purity, high-density SiC particles using a dry self-bonding process, shaped in a “W” configuration with three heating units designed for three-phase power applications. The hot zone surface temperature reaches up to 1600℃, with a maximum operating temperature of 1650℃, delivering energy efficiency, a long lifespan, and excellent thermal uniformity, making it perfect for float glass production and other high-temperature industrial kilns.

Installation Instructions

To ensure the performance and safety of W-Type Silicon Carbide Heating Elements, follow these installation steps:

1. Inspect Element: Check for cracks or damage before installation.
2. Installation Position: Cold ends form a right-angle structure with the hot zone, ideal for furnace roof or side installation in space-constrained or single-side wiring furnaces.
3. Fixing Device: Use ceramic clamps or dedicated clamping devices to avoid direct contact with metal.
4. Power Connection: Compatible with 110-480V three-phase power, ensure resistance matching, and use an SCR regulator for precise temperature control.
5. Ventilation: Keep the installation area well-ventilated to prevent localized overheating.
6. Preheating: Gradually increase power during initial use to avoid thermal shock.
7. Regular Maintenance: Inspect wiring and clamping devices to ensure they are secure and free from looseness or corrosion.

Note: Professionals should perform installation; contact us for detailed guidance.

Application Fields

• Excellent Thermal Uniformity: Three heating units enable multi-zone temperature control, improving furnace temperature consistency.
• Global Support: Backed by overseas service centers for fast response and technical guidance.

Design Recommendations

To optimize the performance of W-Type Silicon Carbide Heating Elements, follow these suggestions:

• Hot Zone Length: Match the hot zone length to the furnace chamber width to avoid insertion into the furnace wall, preventing ablation.
• Cold Zone Length: The cold zone length should match the furnace wall thickness plus an extra 50-150mm for connecting accessories.
• Furnace Aperture: The furnace aperture should be 1.4-1.6 times the cold end diameter to allow free expansion and prevent breakage.
• Spacing Design: Keep a distance of ≥3 times the outer diameter between the element and materials or furnace walls and ≥4 times the outer diameter between element centers for optimal heat distribution.
• Multi-Zone Layout: For wide or tall furnaces, arrange W-Type elements along one side with zoned temperature control to improve uniformity.
• Temperature Control System: Pair with a PID controller for precise temperature control, thereby extending the lifespan of the element.
