Silicon Carbon Rod Series
Shanghai Donghai High-Temperature Silicon Carbon Rods · Core Component for Industrial High-Temp Heating
Product Overview
Carpent New Materials (Shanghai) Co., Ltd. distributes SiC heating elements manufactured by Tokai High Heat, a leading Japanese industrial heating element manufacturer renowned globally for the superior quality and reliable performance of its silicon carbide rods.
Silicon-carbon rods are non-metallic heating elements made primarily from high-purity silicon carbide. They feature uniform heat distribution, strong oxidation resistance, high-temperature tolerance, and long service life, making them essential consumables for industrial high-temperature kilns, heat-treatment furnaces, and laboratory high-temperature equipment.
Key Features
Uniform heat distribution
Uses high-purity SiC material with high density and uniform resistivity to ensure consistent temperature across the heating zone.
High thermal shock resistance
Offers excellent thermal shock resistance, enabling it to withstand rapid temperature fluctuations and minimizing damage caused by thermal stress.
High-temperature resistant
Maximum operating temperature up to 1600°C, meeting the needs of various high-temperature processes.
Long-lasting
Under normal use conditions, the service life can reach 2 to 3 times that of standard heating elements.
Product Model Specifications
Note: The models listed below are representative only; specific specifications can be customized to meet your operating conditions.
SHD/SLD
This series features high-density silicon carbide rods engineered for enhanced corrosion resistance. Building upon the standard SH/SL uniform-diameter design, these units offer upgraded materials to excel in demanding environments while maintaining identical electrical specifications and overall dimensions with SH and SL models. Ideal for use in corrosive media containing chlorine, fluorine, alkalis, lead, halogens, and more. Protective coatings can be selected based on specific operating conditions to further improve oxidation and corrosion resistance. Available Sizes: Ø12–50mm | Total Length ≥3000mm
SG
SG-type silicon carbod rods feature a single-spiral groove design in the heating zone. This structure maintains the energy-saving performance of standard uniform-diameter rods while enabling operation at higher temperatures and delivering superior corrosion resistance under harsh conditions, making it ideal for long-term continuous high-temperature service. Available sizes: Ø14–45 mm | Hot-end length 1000mm | Total length 2000 mm
SUD
The SUD-type silicon carbide heating element consists of two identical, equal-diameter rods. Building on the SU series, it features optimized material performance and a unique structural design for superior energy efficiency, making it ideal for high-temperature industrial heating equipment. Available Sizes: Ø40mm | Hot Zone Length 1500mm | Total Length 1800mm
SW
The SW-type silicon carbide rod consists of three single-phase rods arranged in a W configuration, designed for use with three-phase power supplies. It is primarily used in high-temperature heating equipment such as float glass production lines and large industrial kilns.
SGR
The SGR silicon carbide rod features a dual-spiral groove design, retaining only one cold end for external wiring. This simplifies installation and effectively saves space inside the furnace. With excellent high-temperature and corrosion resistance, the SG and SGR series are ideal for harsh environments and industrial kilns operating above 1400°C. Available sizes: Ø16–45mm | Hot-end length: 1000mm | Total length: 1500mm
