The innovative Leader Electric Heater's core embodies engineering excellence with its U-shaped axially arranged end-welded resistance wires, supported by durable ceramic frames. This design ensures superior heat dissipation, unhindered by shielding between the core and the outer protective sleeve. Achieving a remarkable rated working temperature of 1000 degrees Celsius, the resistance wires are crafted from top-grade materials such as Cr20Ni80 or 0Cr21AI6Nb, providing the surface with a working temperature capability of up to 1200 degrees. The exceptional material composition allows the electric radiation tube to achieve a maximum working temperature of 1000 degrees, supported by high alumina ceramic components. Encased in a meticulously designed cold-drawn, seamless thin-walled steel tube made from 1Cr25Ni20Si2 or 1Cr25Ni35Si2, this protective sleeve boasts exceptional high-temperature oxidation resistance, enhanced creep strength, and carburizing resistance. The thoughtfully selected materials and design principles ensure a high safety factor for this radiant tube. For even more demanding applications, the tube's rated working temperature extends to an impressive 1200 degrees with resistance wires made of 0Cr27AI7Mo2, presenting a surface working temperature reach of 1400 degrees. The electric radiation tube, designed for short-term operation at 1250 degrees, features a robust steel jade porcelain support frame. Its outer sleeve, a feat of cold-drawn engineering, is made from a Fe Ni CrAI Re alloy, furnishing it with high oxidation resistance, capable of enduring long-term service at 1300 degrees Celsius and short-term conditions at 1360 degrees Celsius. Tailored to thrive in challenging environments, including high temperatures, low oxygen partial pressures, and sulfur-containing atmospheres, this radiant tube is the epitome of resilience.
