Expertly engineered with the utmost precision, the straight tube of the W-type radiation tube showcases remarkable high-temperature resistance. Crafted through centrifugal casting using top-quality pit tube materials, it stands as a testament to superior craftsmanship. The bent tube, a masterpiece of precision casting, completes this cutting-edge design. The W-type radiation tube plays a pivotal role in continuous annealing processes, galvanized wire horizontal annealing furnaces, and advanced silicon steel heat treatment furnaces. Operating within a nitrogen and hydrogen-rich protective atmosphere, this groundbreaking radiation tube efficiently utilizes thermal energy from natural gas or coke oven gas combustion. This process ensures the strip steel is heated swiftly and uniformly from ambient temperatures to an impressive 900 degrees Celsius. This accelerated and consistent heating process is crucial for achieving flawless annealing of strip steel, setting an industry benchmark for excellence.
