Crafted with an exquisite level of attention to detail, the straight tube of the W-type radiation tube stands as a testament to high-temperature resistance. This engineering marvel is expertly centrifugally cast from the finest pit tube materials. The bent tube, a brilliant feat of precision casting technology, completes this innovative and groundbreaking design. The W-type radiation tube plays an indispensable role in continuous annealing processes, galvanized wire horizontal annealing furnaces, and the sophisticated silicon steel heat treatment furnaces. Operating within a protective atmosphere rich in nitrogen and hydrogen, this pioneering radiation tube harnesses the immense thermal energy generated during the combustion of natural gas or coke oven gas. This ensures the strip steel is swiftly and uniformly heated from ambient temperatures to a remarkable 900 degrees Celsius. This rapid and consistent heating process is vital to achieving the perfect annealing of strip steel, setting remarkable benchmarks in industrial excellence.
