Core Value

The Custom Straight U W Shape Sic Heating Rods offer ultimate design flexibility for high-temperature industrial electric furnaces, ceramic kilns, glass lehrs, and powder metallurgy equipment. Manufactured from premium high-density recrystallized Green Silicon Carbide (a-SiC) grains via advanced reaction sintering, these versatile elements form an impermeable, self-healing Silicon Dioxide (SiO2) Glass Layer when operating above 900°C. This robust protective shield arrests internal oxidation, enabling stable, continuous thermal performance at temperatures up to 1400°C (2552°F).

By offering a complete portfolio of geometries—from standard Straight Rods (ED/DB) for dual-wall penetration, to U-Shape (2-shank) and W-Shape (4-shank) designs for single-ended roof or sidewall wiring—these heating elements can be tailored to maximize thermal uniformity while minimizing electrical connection complexity. Engineered with low-resistance cold-end terminals seamlessly welded to high-radiance hot zones, they ensure thermal energy is concentrated in the chamber, not lost in the furnace walls. BACKED BY 30+ YEARS MANUFACTURING EXPERIENCE and UNDERGOES MULTIPLE RIGOROUS QUALITY CHECKS to guarantee precise electrical resistance calibration, bridge joint integrity, and exceptional service life across all custom geometries.

✓ 1400°C High-Temperature Durability: Performs continuously up to 1400°C (2552°F) in air and neutral gas atmospheres without structural thermal fatigue.

✓ Versatile Custom Geometries: Available in Straight, U, and W shapes to perfectly match dual-ended or single-ended furnace port configurations.

✓ Self-Healing Anti-Oxidation Coating: Automatically regenerates a dense SiO2 film at high temperatures to protect the internal ceramic matrix.

✓ High Watt Density & Fast Ramp-Up: Accommodates high surface loading (up to 15 W/cm²), enabling rapid kiln heating cycles.

✓ Low-Resistance Cold Terminals: Highly conductive cold-end segments keep terminal clamps cool, preventing electrical arcing and connection burnouts.

✓ Reinforced Bridge Joints: U and W shapes feature specially reinforced hot-welded bridges to eliminate stress fractures during thermal expansion.

HT-Heater vs Standard Market SiC Elements

Shape Configurations & Advantages

• Straight Shape (ED Type): The standard, highly versatile configuration utilized in general high-temperature furnaces. Terminals exit from both ends, making it ideal for symmetrical chamber heating and standard horizontal or vertical installations across the width of the heating chamber.

• U-Shape (DB Type): Features two precisely matched SiC rods connected by a thickened, low-resistance bridge. Both electrical terminals exit from the same side of the furnace. This design dramatically simplifies wiring architecture and minimizes structural heat loss by reducing the required number of cold-end terminal ports on the furnace walls.

• W-Shape: Consists of three integrated SiC heating elements connected at one end, engineered specifically for direct integration with three-phase power supplies. This robust configuration provides highly efficient, uniform thermal distribution across wide-hearth continuous furnaces and large-scale industrial heating spans.

Primary Industrial Applications
