Crafted with unparalleled expertise, the straight tube of the W-type radiation tube is made from high-temperature resistant centrifugally cast pit tube, reflecting our unwavering dedication to quality and durability. The bent tube, shaped through precision casting technology, stands as a testament to our cutting-edge manufacturing prowess. This meticulously engineered W-type radiation tube is ideal for continuous annealing, galvanized wire horizontal annealing furnaces, and silicon steel heat treatment furnaces. Operating within a protective atmosphere enriched with nitrogen and hydrogen, this exceptional radiation tube harnesses the formidable heat energy generated by the combustion of natural gas or coke oven gas. It facilitates rapid and uniform heating of strip steel, elevating its temperature from ambient to an impressive 900 degrees Celsius. This guarantees optimal annealing through superior radiation heat transfer from the outer tube, making it an indispensable, efficient, and precise solution for your heat treatment requirements.
