Crafted with meticulous attention to detail, the straight tube of the W-type radiation tube stands as a paragon of high-temperature resistance, having been centrifugally cast from superior pit tube materials. The bent tube, a marvel of precision casting technology, completes this cutting-edge design. This W-type radiation tube is integral to continuous annealing processes, galvanized wire horizontal annealing furnaces, and the avant-garde silicon steel heat treatment furnaces. Operating within a protective atmosphere enriched with nitrogen and hydrogen, this pioneering radiation tube meticulously harnesses the thermal energy generated during the combustion of natural gas or coke oven gas. This ensures strip steel is rapidly and uniformly heated from ambient temperatures to an impressive 900 degrees Celsius. Such expedited and consistent heating is paramount to the flawless annealing of strip steel, redefining industrial excellence.
