Crafted with meticulous attention to detail, the straight tube of the W-type radiation tube showcases exceptional high-temperature resistance, thanks to its centrifugal casting from superior pit tube materials. The bent tube, a testament to precision casting technology, completes this remarkable and innovative design. This W-type radiation tube is indispensable in continuous annealing processes, galvanized wire horizontal annealing furnaces, and sophisticated silicon steel heat treatment furnaces. Within a protective atmosphere brimming with nitrogen and hydrogen, this pioneering radiation tube ingeniously captures the thermal energy from the combustion of natural gas or coke oven gas. This ensures the strip steel is swiftly and uniformly heated from ambient conditions to an impressive 900 degrees Celsius. This accelerated and consistent heating process is pivotal to achieving the perfect annealing of strip steel, setting incredible new standards in industrial excellence and efficiency.
