The innovative heating core of the electric heating radiant tube showcases precision engineering, featuring U-shaped, axially arranged end welded resistance wires housed within robust ceramic support frames. With no barriers between the core and the outer protective sleeve, optimal heat dissipation is effortlessly achieved. The rated working temperature of this extraordinary electric radiation tube reaches an impressive 1000 degrees Celsius. Crafted from premium materials, the resistance wire options include Cr20Ni80 or 0Cr21AI6Nb, enabling the surface working temperature to soar up to 1200 degrees Celsius. Constructed with high alumina ceramic parts, the support frame enhances the tube’s structural integrity. The outer protective sleeve, a cold drawn seamless thin-walled marvel, is made from 1Cr25Ni20Si2 or 1Cr25Ni35Si2, showcasing superior high-temperature oxidation resistance, remarkable high-temperature creep strength, and the ability to resist carburizing. Thoughtfully designed and meticulously selected materials ensure a high safety factor. The rated working temperature of the radiant tube can reach 1200 degrees Celsius with 0Cr27AI7Mo2 resistance wire, and the surface temperature can peak at 1400 degrees Celsius. The short-term maximum working temperature can reach 1250 degrees Celsius with steel jade porcelain support frames. The outer protective sleeve, crafted from Fe Ni CrAI Re alloy, excels with its exceptional oxidation resistance. It can endure long-term exposure to 1300 degrees Celsius in an oxidizing atmosphere, handling short-term exposures at 1360 degrees Celsius. Perfectly suited for high temperature, low oxygen partial pressure, and SC containing environments, this product exemplifies cutting-edge thermal technology.
