The straight tube of the W-type radiation tube is masterfully crafted from high-temperature resistant centrifugally cast pit tube, epitomizing our unwavering dedication to durability and superior quality. Our bent tube, produced via state-of-the-art precision casting technology, showcases the pinnacle of manufacturing excellence. Designed with meticulous attention to detail, the W-type radiation tube serves perfectly in continuous annealing, galvanized wire horizontal annealing furnaces, and silicon steel heat treatment furnaces. Within a protective atmosphere enriched with nitrogen and hydrogen, this exceptional radiation tube harnesses the immense heat energy from natural gas or coke oven gas combustion. It ensures the swift and uniform heating of strip steel from ambient temperature to a remarkable 900 degrees Celsius, promoting optimal annealing through superior radiation heat transfer from the outer tube. This extraordinary product stands as a beacon of efficiency and precision, proving indispensable for all your heat treatment needs.
