The heart of our electric heating radiant tube is ingeniously crafted with U-shaped, axially aligned end-welded resistance wires and robust ceramic support frames, ensuring no barriers between the core and the protective sleeve, leading to excellent heat dissipation. This marvel operates at a rated temperature of 1000 degrees, with resistance wires forged from Cr20Ni80 or 0Cr21AI6Nb. The surface temperature glows at an impressive 1200 degrees. Constructed to reach a peak temperature of 1000 degrees, the support frame incorporates high alumina ceramic elements. Encased within a cold-drawn, seamless, thin-walled, heat-resistant steel pipe of 1Cr25Ni20Si2 or 1Cr25Ni35Si2, this material excels in high-temperature oxidation resistance, outstanding creep strength, and carburizing resistance. Our thoughtfully designed radiation tube prioritizes safety, achieving a rated operational temperature of 1200 degrees. The resistance wire, 0Cr27AI7Mo2, radiates a surface warmth of 1400 degrees, with the electric radiation tube enduring short-term peaks at 1250 degrees. The frame, crafted from steel jade porcelain, is shielded by a cold-drawn seamless thin-walled pipe of Fe Ni CrAI Re alloy, boasting exceptional oxidation resistance. Capable of sustained operation at 1300 degrees in oxidizing atmospheres, it resists short-term oxidation up to 1360 degrees, perfect for high-temperature, low-oxygen, and SC-laden environments.
