The straight tube of the W-type radiation tube is meticulously crafted from high-temperature resistant centrifugally cast pit tube, a testament to our unwavering commitment to durability and unparalleled quality. Our bent tube, forged using precision casting technology, stands as a beacon of cutting-edge manufacturing excellence. The W-type radiation tube is ingeniously designed for seamless integration into continuous annealing, galvanized wire horizontal annealing furnaces, and silicon steel heat treatment furnaces. Within a protective atmosphere infused with nitrogen and hydrogen, this extraordinary radiation tube masterfully harnesses the formidable heat energy produced by natural gas or coke oven gas combustion. It achieves the rapid and uniform heating of strip steel from ambient temperature to approximately 900 degrees Celsius, ensuring optimal annealing through superior radiation heat transfer from the meticulously crafted outer tube. This exemplary product embodies efficiency and precision, making it an indispensable solution for your sophisticated heat treatment needs.
