SPARK Ceramic Bundle Rod Radiant Tube Heating Core | Industrial Furnace Heating Element
As a core heating component for electric radiant tubes, the SPARK ceramic bundle rod radiant tube heating core is engineered for high-performance indirect heating in industrial thermal processing. Manufactured by Beijing Shougang Gitane New Materials Corporation with 70 years of expertise in special electric heating alloys, this heating core integrates self-produced premium FeCrAl and NiCr resistance wires with high-purity ceramic insulators, delivering stable, uniform and long-lasting heating for various industrial furnaces. It serves as a reliable import-replacement solution for global heat treatment manufacturers seeking consistent quality and cost efficiency.
Built with a modular ceramic-supported structure, each radiant tube heating core features carefully arranged heating alloy coils fixed by segmented ceramic spacers. This design ensures excellent electrical insulation, outstanding thermal shock resistance and robust structural stability even under long-term high-temperature operation, effectively reducing element deformation and short-circuit risks under frequent thermal cycling.
All heating elements adopt SPARK brand electric heating alloys produced in-house by Gitane. Customers can select from FeCrAl grades including 0Cr25Al5, HRE, SGHYZ and SGHT as well as NiCr grades such as Cr20Ni80 and Cr30Ni70, based on working temperature and furnace atmosphere requirements. Our strict material quality control guarantees high electrical resistivity, excellent electro-thermal conversion efficiency and superior high-temperature oxidation resistance, which directly extends the service cycle of the heating core and reduces unplanned furnace downtime.
Key Performance Advantages
Ⅰ. Uniform Radiant Heating Output
The evenly distributed alloy coils and ceramic supporting structure generate consistent radiant heat along the full tube length, minimizing temperature difference inside the furnace chamber and improving workpiece processing uniformity. It is especially suitable for precision heat treatment processes with strict temperature control requirements.
Ⅱ、Excellent High-Temperature Durability
With optimized alloy composition and rare earth modification technology, SPARK heating alloys form a dense protective oxide film at elevated temperatures, effectively resisting oxidation, carburization and corrosion in controlled atmosphere environments. The heating core maintains stable performance during long-term operation up to 1425℃, matching the performance of imported premium-grade radiant tube heating cores.
Ⅲ、Low Maintenance & Reduced Total Cost
The robust ceramic support structure and high-grade alloy wire significantly extend service life compared with ordinary heating cores, lowering replacement frequency and cutting overall maintenance, labor and production costs for industrial furnace operators.
Wide Industrial Applications
SPARK ceramic bundle rod radiant tube heating cores are widely applied in various industrial heating equipment, including atmosphere-controlled heat treatment furnaces, metal annealing furnaces, powder metallurgy sintering furnaces, brazing furnaces, hardening furnaces, ceramic firing lines and glass processing furnaces. They serve key industries such as automobile manufacturing, building materials, electronic components, solar power and new energy materials, covering most demanding industrial thermal processing scenarios.
