Silicon carbide heating elements are non-metal high-temperature electric heating components manufactured from selected high-quality green silicon carbide. Through advanced processing including blank formation, high-temperature siliconization, and recrystallization, these elements deliver exceptional performance in demanding thermal environments.

• Withstands surface temperatures up to 1500°C
• Available in multiple configurations: Rod, U-shape, W-shape, Single Spiral, and Double Spiral
• Comprehensive size range to meet diverse application requirements
• High heat output per unit surface area for efficient operation
• Exceptional mechanical strength and thermal shock resistance
• Clean, silent operation with no air pollution emissions

These silicon carbide heating elements are engineered for high-temperature electric furnaces and heating systems across multiple industries including magnetic materials, ceramics, metallurgy, glass manufacturing, and mechanical processing applications.

• U-Type: Single-phase configuration with terminals at one end for energy efficiency
• W-Type: Three-phase design optimized for float glass processes
• Spiral Type: Enhanced heat and corrosion resistance with energy-saving terminals
• Double Spiral Type: Superior performance in rigorous conditions with low-resistance cold ends
• GC/GD Type: High-density, high-purity silicon carbide construction for economical operation

• Protect from moisture during storage and installation to maintain performance
• Pre-test resistance values with tolerance not exceeding 10% between elements
• Handle with care during installation and maintenance operations
• Gradually increase voltage during initial furnace operation; avoid immediate full loading
• Replace damaged elements following resistance increase patterns; replace multiple elements if resistance increases significantly
