The heart of the Ceramic Bobbin Heating Electric Heater for Furnace - Leader Brand, China Origin, is ingeniously crafted with U-shaped axially arranged end-welded resistance wires set within robust ceramic support frames. Unshackled by any shielding between its inner core and outer protective sleeve, this design ensures optimal heat dissipation. This radiant tube boasts a rated working temperature of 1000 degrees, featuring resistance wires made from Cr20Ni80 or 0Cr21AI6Nb, while its surface can endure up to 1200 degrees. Crafted to withstand high temperatures, the heater's core material permits a maximum working temperature of 1000 degrees, with support frames made from high alumina ceramics. The outer shell is a precisely engineered cold-drawn seamless thin-walled heat-resistant steel tube, composed of either 1Cr25Ni20Si2 or 1Cr25Ni35Si2, offering superb high-temperature oxidation resistance, impressive high-temperature creep strength, and notable carburizing resistance. With a meticulous safety-oriented design and material choice, this radiant tube’s superior construction with resistance wire of 0Cr27AI7Mo2 achieves a rated working temperature of 1200 degrees, and a surface temperature of up to 1400 degrees. Its maximum short-term operating temperature reaches 1250 degrees, supported by a steel jade porcelain frame. The outer protective sleeve, an Fe Ni CrAI Re alloy marvel, delivers high oxidation resistance, enabling continuous operation at 1300 degrees Celsius in oxidizing atmospheres and short-term resilience up to 1360 degrees Celsius. Perfectly suited for challenging high-temperature, low-oxygen pressure, and sulfur-containing environments.
