The heart of our Reliable Ceramic Bobbin Electric Heater is ingeniously crafted with U-shaped axially aligned resistance wires seamlessly welded at the ends and supported by robust ceramic frames. Unhindered by any internal shielding, this innovative design ensures superior heat dissipation. Crafted for excellence, the electric radiation tube operates at a commendable rated temperature of 1000 degrees Celsius, using premium resistance wire materials like Cr20Ni80 or 0Cr21AI6Nb, with the surface temperature capability soaring to an impressive 1200 degrees. Boasting an exceptional safety factor, it triumphs in delivering unparalleled performance. The high-alumina ceramic parts meticulously construct the support frame, while the outer sleeve, a marvel of engineering, is composed of cold-drawn seamless heat-resistant steel – 1Cr25Ni20Si2 or 1Cr25Ni35Si2. Engineered for resilience, this material exhibits remarkable high-temperature oxidation resistance, formidable creep strength, and notable carburizing resistance. At its pinnacle, the electric radiation tube achieves a rated working temperature of 1200 degrees. The resistance wire material 0Cr27AI7Mo2 elevates the surface working temperature to a staggering 1400 degrees, with short-term capacities reaching 1250 degrees. Steel jade porcelain forms the core of the support frame, while the outer protective sleeve, forged from Fe Ni CrAI Re alloy, resists oxidation at extraordinary temperatures of up to 1360 degrees Celsius. Designed for extreme conditions, it excels in high-temperature, low-oxygen, and sulfur-carbide environments.
