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