At the heart of the Leader Ceramic Heating Radiant Tube Electric Heater is an ingeniously designed heating core. Crafted with U-shaped, axially arranged end-welded resistance wires and ceramic support frames, this core ensures optimal heat dissipation with no shielding between the inner core and the outer protective sleeve. The electric radiation tube boasts a remarkable rated working temperature of 1000 degrees Celsius, with surface temperatures soaring up to 1200 degrees, thanks to resistance wires made from either Cr20Ni80 or 0Cr21AI6Nb. The high-alumina ceramic parts of the support frame further enhance durability. Encased in a cold-drawn, seamless thin-walled heat-resistant steel pipe made from 1Cr25Ni20Si2 or 1Cr25Ni35Si2, the heater exhibits superior high-temperature oxidation resistance, impressive high-temperature creep strength, and resistance to carburizing. The thoughtfully designed radiation tube guarantees a high safety factor, with a rated working temperature reaching 1200 degrees. The resistance wire, composed of 0Cr27AI7Mo2, elevates the surface working temperature to an astounding 1400 degrees. It can endure short-term temperatures up to 1250 degrees, with the support frame crafted from steel jade porcelain. The outer protective sleeve, made from Fe Ni CrAI Re alloy, withstands continuous operation at 1300 degrees Celsius in oxidizing environments and short-term exposure up to 1360 degrees Celsius, perfect for high temperature and low oxygen settings.
