The heating core of the exceptional Leader Electric Heater Furnace Element is ingeniously constructed with U-shaped, axially arranged, end-welded resistance wires supported by robust ceramic frames. Ingeniously designed without shielding between the core and its protective sleeve, it ensures superior heat dissipation. This remarkable electric radiation tube boasts a rated working temperature of 1000 degrees Celsius, featuring resistance wires crafted from Cr20Ni80 or 0Cr21AI6Nb materials. The surface working temperature impressively reaches up to 1200 degrees. Constructed using high alumina ceramic components, the support frame is coupled with an outer sleeve of cold drawn seamless thin-walled heat-resistant steel pipe, fashioned from 1Cr25Ni20Si2 or 1Cr25Ni35Si2, ensuring excellent high-temperature oxidation resistance and formidable strength against carburizing. The design and material choice reflect an exceptional safety factor. Further enhancing its capabilities, the rated working temperature rises to 1200 degrees for tubes made with 0Cr27AI7Mo2 resistance wire, reaching a surface temperature of 1400 degrees. The highest short-term operational capacity of 1250 degrees is achieved with steel jade porcelain support frames and an outer protective sleeve composed of Fe Ni CrAI Re alloy, ensuring consistent performance even in harsh, high-temperature, low-oxygen, and SC-containing environments.
