The heart of the Leader Electric Heater Furnace Element lies in its sophisticated heating core. This electric heating radiant tube features a meticulously crafted U-shaped axially arranged end welded resistance wire design, supported by resilient ceramic frames. The absence of shielding between the inner core and the outer protective sleeve ensures excellent heat dissipation. Designed for demanding applications, the electric radiation tube's rated working temperature is an impressive 1000 degrees Celsius, with resistance wires crafted from robust materials such as Cr20Ni80 or 0Cr21AI6Nb. These wires enable a surface working temperature soaring up to 1200 degrees Celsius. When fabricated from such premium materials, the tube can achieve a maximum working threshold of 1000 degrees, supported by high alumina ceramic components. Encased in a cold drawn seamless thin-walled heat-resistant steel pipe made from 1Cr25Ni20Si2 or 1Cr25Ni35Si2, the outer protective sleeve boasts exceptional high-temperature oxidation resistance, remarkable creep strength, and offers resistance to carburizing. This thoughtfully designed radiation tube showcases a high safety factor in material selection, with some configurations reaching a rated working temperature of 1200 degrees and a surface temperature potential of 1400 degrees, crafted from 0Cr27AI7Mo2 resistance wire. Achieving a maximum short-term working temperature of 1250 degrees, supported by steel jade porcelain frames, the outer protective sleeve, made from Fe Ni CrAI Re alloy, excels in oxidation resistance. It is adept at enduring long-term operation in oxidizing atmospheres up to 1300 degrees Celsius, withstanding short-term conditions up to 1360 degrees. Perfectly engineered for high-temperature, low oxygen, and SC environments, this tube represents the epitome of reliability and technological advancement.
