The heating core of the Leader Electric Heater Furnace Element is ingeniously crafted with U-shaped, axially arranged end-welded resistance wires and robust ceramic support frames, ensuring unmatched performance. With no shielding between the core and outer protective sleeve, heat dissipation is optimized for efficiency. The electric radiation tube boasts a rated working temperature of 1000 degrees, using high-quality Cr20Ni80 or 0Cr21AI6Nb resistance wire, with a surface working temperature soaring to 1200 degrees. Designed with precision, the support frame is crafted from high alumina ceramic, while the seamless, thin-walled outer sleeve is made from cold-drawn heat-resistant steel, such as 1Cr25Ni20Si2 or 1Cr25Ni35Si2. These materials offer superior high-temperature oxidation resistance, remarkable creep strength, and carburization resistance. The cutting-edge design ensures a high safety factor, with the electric radiation tube reaching a phenomenal 1200-degree working temperature using 0Cr27AI7Mo2 resistance wire, and a surface temperature of up to 1400 degrees. For short-term applications, temperatures can peak at 1250 degrees, utilizing steel jade porcelain support frames. The outer protective sleeve is a marvel of engineering, made from Fe Ni CrAI Re alloy, offering exceptional oxidation resistance. It operates reliably in extreme conditions, withstanding 1300 degrees Celsius over extended periods and 1360 degrees Celsius in short-term oxidizing atmospheres. This makes it ideal for high-temperature environments with low oxygen and SC-containing atmospheres.
