Introducing the cutting-edge core of our electric heating radiant tube, featuring a meticulously constructed heating element composed of U-shaped, axially aligned end-welded resistance wires and durable ceramic support frames. Uniquely designed without any shielding between the core and its protective sleeve, it ensures optimal heat dissipation. Engineered to operate at a rated temperature of 1000 degrees, the resistance wire is crafted from materials such as Cr20Ni80 or 0Cr21AI6Nb, with the surface temperature capable of reaching a remarkable 1200 degrees. This superior material composition allows the electric radiation tube to sustain a maximum working temperature of 1000 degrees. The robust support frame made of high-quality alumina ceramic parts and an outer protective sleeve of cold-drawn seamless thin-walled heat-resistant steel, specifically 1Cr25Ni20Si2 or 1Cr25Ni35Si2, provides excellent high-temperature oxidation resistance and impressive resistance to carburization, ensuring durability and safety. The rated working temperature is elevated to 1200 degrees with resistance wire made of 0Cr27AI7Mo2, reaching surface temperatures of up to 1400 degrees. For short-term conditions, it withstands temperatures up to 1250 degrees with steel jade porcelain support, while the Fe Ni CrAI Re alloy protective sleeve offers robust oxidation resistance, maintaining performance at 1300 degrees Celsius in oxidizing atmospheres and enduring short-term exposure to 1360 degrees. Perfectly engineered for environments demanding high temperature, low oxygen partial pressure, and SC containment.
