Behold the sophistication of our Innovative Ceramic Bobbin Electric Heater for Furnace, meticulously crafted by Leader Brand, hailing from the heart of China. The heating core of this radiant electric heating tube is an engineering marvel, composed of U-shaped, axially aligned, end-welded resistance wires supported by robust ceramic frames. This design ensures that there is no barrier between the inner core and its outer protective sleeve, allowing for superior heat dissipation. Rated to perform optimally at temperatures up to 1000 degrees, this exceptional heating element utilizes resistance wires crafted from Cr20Ni80 or 0Cr21AI6Nb, with a surface working temperature reaching a scorching 1200 degrees. The pinnacle of its functionality sees it operating at an impressive maximum of 1000 degrees, with the support frame composed of high-grade alumina ceramic elements. The outer protective sleeve is a masterpiece of durability and heat resistance, crafted from cold-drawn seamless thin-walled steel pipes made of 1Cr25Ni20Si2 or 1Cr25Ni35Si2. These materials exemplify excellent high-temperature oxidation resistance, formidable high-temperature creep strength, and commendable carburizing resistance. Each element of this radiant tube is designed with safety and performance in mind, boasting a rated working temperature of 1200 degrees, with resistance wires of 0Cr27AI7Mo2, achieving a surface working temperature of 1400 degrees. For short bursts, the tube can withstand up to 1250 degrees, supported by the robust steel jade porcelain frame. The outer protective sleeve, masterfully constructed from Fe Ni CrAI Re alloy, is renowned for its remarkable oxidation resistance, able to endure prolonged exposure of up to 1300 degrees Celsius in oxidizing environments, and can handle short-term oxidation at an impressive 1360 degrees Celsius. This makes it ideal for high-temperature operations in low oxygen partial pressure and SC-rich environments.
