Introducing our innovative Ceramic Bobbin Heating Electric Heater for Furnace - crafted with precision and engineered for excellence. The core of this electric heating radiant tube is designed with U-shaped, axially arranged resistance wires, expertly welded, and supported by high-grade ceramic frames. Uninterrupted by shielding, it ensures optimal heat dissipation. This radiant tube boasts a remarkable rated working temperature of 1000 degrees Celsius, utilizing Cr20Ni80 or 0Cr21AI6Nb resistance wire, with surface temperatures reaching up to 1200 degrees. For enhanced performance, the maximum working temperature can achieve 1000 degrees, supported by high alumina ceramic frames. The protective sleeve is crafted from cold-drawn seamless thin-walled heat-resistant steel, specifically 1Cr25Ni20Si2 or 1Cr25Ni35Si2, offering excellent high-temperature oxidation resistance, impressive high-temperature creep strength, and significant carburizing resistance. The comprehensive design and superior material selection ensure a high safety factor, with the rated working temperature elevated to 1200 degrees and the resistance wire material upgraded to 0Cr27AI7Mo2, achieving surface temperatures of 1400 degrees. The maximum short-term operation reaches 1250 degrees, supported by durable steel jade porcelain frames. The outer protective sleeve is refined with a Fe Ni CrAI Re alloy, offering superior oxidation resistance. This robust radiation tube is capable of continuous operation at 1300 degrees Celsius in oxidizing atmospheres and withstands short-term oxidation at 1360 degrees, making it ideal for high-temperature, low oxygen, and sulfur-containing environments.
