Crafted with meticulous attention to detail, the straight tube of the W-type radiant tube is a masterpiece of engineering excellence. It is imbued with unparalleled high-temperature resistance, having been centrifugally cast from the finest pit tube materials. The bent tube, a marvel of modern precision casting technology, seamlessly completes this groundbreaking design. This W-type radiant tube is indispensable in continuous annealing processes, galvanized wire horizontal annealing furnaces, and the sophisticated silicon steel heat treatment furnaces. Operating in a protective atmosphere enriched with nitrogen and hydrogen, this pioneering radiant tube masterfully harnesses the thermal energy emitted during the combustion of natural gas or coke oven gas. This ensures the strip steel is swiftly and uniformly heated from ambient temperatures to an extraordinary 900 degrees Celsius. This rapid and consistent heating process is essential for the flawless annealing of strip steel, establishing new benchmarks in industrial excellence.
