Built from high-purity silicon carbide, these elements leverage the principle of electric resistance heating. When electric current flows through the SiC material, it generates intense heat. What makes them indispensable is their ability to operate at temperatures up to 1,625°C (2,927°F) while maintaining structural integrity and performance.
Unlike combustion-based heating, which can result in energy loss, inconsistent temperatures, and environmental concerns, electric heating solutions powered by Globar® silicon carbide (SiC) heating elements offer:
- Unmatched heat resistance: Functioning at temperatures as high as 1,625°C (2,927°F).
- Long operational life: Designed to withstand oxidation, corrosion, and thermal stress.
- Higher energy utilization: Direct conversion of electrical energy into heat minimizes waste and maximizes efficiency.
- Precision and uniformity: Globar® elements provide stable, controlled heating that eliminates fluctuations common in gas-fired systems.
- Cleaner operations: The removal of combustion-based heating reduces CO₂ emissions, completely removes NOx and Sox, aligns with environmental regulations, and creates safer working conditions.
- Scalability and adaptability: Globar® elements are designed to integrate into existing systems, allowing for seamless transitions to electric heating across various industries.
Globar® grades tailored to every need
Kanthal offers a comprehensive portfolio of Globar® heating element grades to meet the specific demands of various industries:
Steel – Globar® AS
- Applications: Steel slab reheating, heat treatment of specialty steels.
- Why it works: Steel slab reheating processes involve high thermal loads and demand consistent temperature distribution to prevent defects and ensure structural integrity. Globar® AS heating elements excel in providing reliable, even heating across slabs, improving rolling outcomes while minimizing energy loss and process downtime.
Glass – Globar® SG
- Applications: Container glass forehearths, glass melting.
- Why it works: To produce glass, maintaining precise forehearth temperatures is essential to control viscosity and achieve flawless clarity. Globar® SG elements deliver consistent heat output, resisting the corrosive effects of molten glass environments and ensuring uninterrupted, high-quality production.
Lithium-ion batteries – Globar® SD and AS
- Applications: Calcination of cathode materials, thermal processing of anode materials.
- Why it works: In producing lithium-ion batteries, cathode calcination, and anode processing require controlled heating to stabilize materials and improve electrochemical performance. Globar® SD and AS provide the high-temperature uniformity necessary for optimizing material consistency and energy density, ensuring batteries meet the stringent demands of modern energy storage systems.
Universal solutions across industries
From ceramics sintering to electronics manufacturing, Globar® grades (HD Max, SD, AS, SG) deliver tailored solutions that meet the rigorous demands of diverse industrial processes.
