The straight tube of the W-type radiation tube is expertly crafted from high-temperature-resistant centrifugally cast pit tube, showcasing our steadfast dedication to durability and superior quality. Our bent tube, manufactured with precision casting technology, exemplifies state-of-the-art manufacturing craftsmanship. The W-type radiation tube is intricately designed for application in continuous annealing, galvanized wire horizontal annealing furnaces, and silicon steel heat treatment furnaces. Operating in a protective atmosphere infused with nitrogen and hydrogen, this exceptional radiation tube harnesses the substantial heat energy produced by natural gas or coke oven gas combustion. It achieves swift and consistent heating of strip steel from room temperature to nearly 900 degrees Celsius, ensuring optimal annealing through advanced radiation heat transfer from the outer tube. This outstanding product epitomizes efficiency and precision, rendering it an essential solution for your heat treatment requirements.
