Crafted with unparalleled precision and meticulous attention to detail, the straight tube of the W-type radiation tube showcases extraordinary high-temperature resistance. It is centrifugally cast from superior pit tube materials, embodying the pinnacle of industrial craftsmanship. The bent tube, a testament to precision casting technology, completes this innovative and exceptional design. This W-type radiation tube is indispensable in continuous annealing processes, galvanized wire horizontal annealing furnaces, and sophisticated silicon steel heat treatment furnaces. Under a protective atmosphere rich in nitrogen and hydrogen, this pioneering radiation tube expertly harnesses thermal energy emitted during the combustion of natural gas or coke oven gas. This ensures that strip steel is rapidly and uniformly heated from ambient temperatures to a remarkable 900 degrees Celsius. This expedited and consistent heating process is crucial for achieving the perfect annealing of strip steel, setting unprecedented standards in industrial excellence.
