The straight tube of our W-type radiation tube is an enduring symbol of durability and quality, meticulously crafted from high-temperature resistant centrifugally cast pit tube. Our bent tube, a pinnacle of precision casting technology, reflects cutting-edge manufacturing prowess. Designed with meticulous attention to detail, the W-type radiation tube excels 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 intense heat energy from natural gas or coke oven gas combustion. It swiftly and uniformly elevates the temperature of strip steel from ambient to a remarkable 900 degrees Celsius, ensuring optimal annealing through superior radiation heat transfer from the outer tube. This exemplary product is a paragon of efficiency and precision, making it an indispensable solution for your most demanding heat treatment applications.
