The innovative heating core of our electric heating radiant tube is engineered for optimal performance. It features U-shaped, axially aligned end-welded resistance wires, supported by robust ceramic frames, ensuring exceptional heat dissipation. Designed without shielding between the core and the protective sleeve, it excels in thermal management. Operating at a rated temperature of 1000 degrees, the resistance wire options include Cr20Ni80 or 0Cr21AI6Nb, with a surface potential reaching 1200 degrees. Crafted with high alumina ceramic, the support frame provides unparalleled durability. The outer protective sleeve, composed of cold-drawn seamless thin-walled heat-resistant steel (1Cr25Ni20Si2 or 1Cr25Ni35Si2), offers superior high-temperature oxidation resistance, creep strength, and carburization resistance. Our design boasts a remarkable safety factor, with a rated working temperature of 1200 degrees. Advanced materials like 0Cr27AI7Mo2 ensure a surface temperature of up to 1400 degrees, and short-term resilience at 1250 degrees. Enveloped in steel jade porcelain, the frame guarantees strength, while the Fe Ni CrAI Re alloy sleeve ensures sustained operation at 1300 degrees Celsius in oxidizing environments, with short-term endurance up to 1360 degrees. Perfect for high-temperature, low-oxygen, and sulfur-containing settings.
