The heating core of our Compact Leader Electric Heater Furnace Element is a marvel of engineering, composed of U-shaped axially arranged end-welded resistance wires seamlessly integrated with ceramic support frames. This design ensures optimal heat dissipation with no shielding interfering between the inner core and the outer protective sleeve. Impressively, the electric radiant tube has a rated working temperature of 1000 degrees, utilizing high-quality resistance wires made from Cr20Ni80 or 0Cr21AI6Nb, reaching surface temperatures up to 1200 degrees. When crafted from this material, our electric radiation tubes can achieve a remarkable maximum working temperature of 1000 degrees, supported by components made of high alumina ceramics. Encased in a cold-drawn, seamless, thin-walled heat-resistant steel sleeve composed of 1Cr25Ni20Si2 or 1Cr25Ni35Si2, the tube boasts excellent high-temperature oxidation resistance, superior high-temperature creep strength, and notable carburizing resistance. The robust design and carefully curated material selection bestow a high safety factor upon this radiation tube, rated for 1200 degrees, with resistance wire material 0Cr27AI7Mo2 enabling surface temperatures of 1400 degrees. The short-term maximum working temperature can reach an astounding 1250 degrees, further supported by steel jade porcelain frames. The protective outer sleeve, crafted from Fe Ni CrAI Re alloy, offers unparalleled oxidation resistance, tolerating prolonged operation at 1300 degrees Celsius in oxidizing atmospheres and short-term exposure to 1360 degrees Celsius, making it exceptionally suited for high-temperature, low oxygen environments, and conditions containing sulfur compounds.
