The straight tube of the W-type radiation tube is an engineering marvel, expertly crafted from high-temperature resistant centrifugally cast pit tube material. This showcases our unwavering dedication to delivering unparalleled durability and quality. Our bent tube, a masterpiece of precision casting technology, elevates manufacturing excellence to new heights. Purposefully designed for continuous annealing, galvanized wire horizontal annealing furnaces, and silicon steel heat treatment furnaces, the W-type radiation tube operates within a protective atmosphere enriched with nitrogen and hydrogen. It harnesses the immense heat energy of natural gas or coke oven gas combustion, swiftly and evenly elevating strip steel temperatures from ambient levels to an impressive 900 degrees Celsius. This ensures optimal annealing with superior radiation heat transfer from the outer tube, making this product an exemplar of efficiency and precision. It stands as an indispensable solution for all your heat treatment needs.
