Exquisitely engineered with a fine eye for detail, the straight tube of the W-type radiation tube showcases exceptional high-temperature resistance, expertly centrifugally cast from premium-grade pit tube materials. This is complemented by the bent tube, a testament to the marvels of precision casting technology, culminating in a groundbreaking design. This W-type radiation tube is indispensable in continuous annealing processes, galvanized wire horizontal annealing furnaces, and the advanced silicon steel heat treatment furnaces. In a protective atmosphere brimming with nitrogen and hydrogen, this cutting-edge radiation tube masterfully captures the thermal energy released during the combustion of natural gas or coke oven gas. This ensures rapid and even heating of strip steel from ambient temperatures to a remarkable 900 degrees Celsius. This swift and consistent heating process is vital for achieving immaculate annealing of strip steel, raising the bar in industrial excellence to unprecedented heights.
