The core of the electric heating radiant tube is ingeniously crafted with precision. It features U-shaped, axially arranged end-welded resistance wires paired with ceramic support frames, all contributing to exceptional heat dissipation. With no intermediary shielding, the inner core seamlessly interacts with the outer protective sleeve, ensuring optimal performance. Rated to operate at a working temperature of 1000 degrees, this sophisticated system relies on high-quality resistance wires made from Cr20Ni80 or 0Cr21AI6Nb. The surface temperature prowess reaches an impressive 1200 degrees. The pinnacle of performance for this electric radiation tube, crafted from premium materials, achieves a remarkable 1000-degree threshold. The support structure is meticulously constructed from high alumina ceramic parts, while the outer protective sleeve, a marvel of engineering, is a cold-drawn seamless thin-walled steel pipe made from 1Cr25Ni20Si2 or 1Cr25Ni35Si2. This material excels in high-temperature oxidation resistance, offers significant high-temperature creep strength, and provides reliable resistance to carburizing. The design and material composition of this radiation tube exemplify unparalleled safety standards, with the rated temperature soaring to 1200 degrees using resistance wires of 0Cr27AI7Mo2. Surface temperatures ascend to a remarkable 1400 degrees, with short-term peaks reaching 1250 degrees. The support frame is crafted from robust steel jade porcelain, and the protective sleeve is manufactured from a cold-drawn seamless thin-walled Fe Ni CrAI Re alloy steel pipe, renowned for its exceptional oxidation resistance. It operates seamlessly in environments with challenging conditions like high temperatures, low oxygen partial pressure, and the presence of SC-containing atmospheres, withstanding temperatures up to 1360 degrees Celsius in oxidizing settings.
