Crafted with meticulous attention to detail, the straight tube of the W-type radiation tube boasts exceptional high-temperature resistance, having been centrifugally cast from the finest pit tube materials. The bent tube, a marvel of cutting-edge precision casting technology, completes this innovative design with elegance. This remarkable W-type radiation tube finds its essential applications in continuous annealing processes, galvanized wire horizontal annealing furnaces, and the sophisticated silicon steel heat treatment furnaces. Within a protective atmosphere enriched with nitrogen and hydrogen, this pioneering radiation tube harnesses the intense thermal energy emitted during the combustion of natural gas or coke oven gas. This ensures that the strip steel is rapidly and evenly heated from ambient temperatures to an impressive 900 degrees Celsius. Such expedited and uniform heating is crucial for achieving the perfect annealing of strip steel, setting new standards in industrial excellence and performance.
