Introducing the remarkable High-Quality Ceramic Bobbin Heating Electric Heater for Furnace by the acclaimed Leader Brand, meticulously engineered by Jiangsu Leader Special Steel Products Co., Ltd. This innovative electric heating radiant tube features a sophisticated heating core composed of U-shaped, axially aligned end-welded resistance wires harmoniously integrated with ceramic support frames. Ingeniously designed for optimum heat dissipation, it ensures an unhindered thermal flow between the inner core and its protective sleeve. Expertly crafted with resistance wire materials such as Cr20Ni80 or 0Cr21AI6Nb, this tube operates efficiently at a rated working temperature of 1000 degrees, reaching surface temperatures up to 1200 degrees. Boasting high alumina ceramic parts for the support frame and cold-drawn seamless thin-walled heat-resistant steel pipes made from 1Cr25Ni20Si2 or 1Cr25Ni35Si2 for the outer protective sleeve, this tube epitomizes high-temperature oxidation resistance, superior creep strength, and carburizing resistance. Designed with an exceptional safety factor, the electric radiation tube has a rated working temperature of 1200 degrees and can reach a surface temperature of 1400 degrees with its 0Cr27AI7Mo2 resistance wire. The pinnacle of short-term working temperatures is a formidable 1250 degrees. Constructed with steel jade porcelain support frames and encased in a heat-resistant Fe Ni CrAI Re alloy pipe, it stands resilient against oxidation, enduring long-term exposure at 1300 degrees in oxidizing atmospheres, and short-term resistance at 1360 degrees, making it ideal for high-temperature, low-oxygen, and SC-environment operations.
