The straight tube of the W-type radiation tube is meticulously crafted from high-temperature resistant centrifugally cast pit tubes, reflecting our unwavering commitment to durability and peerless quality. Our elegantly bent tube, fashioned using precision casting technology, stands as a beacon of modern manufacturing excellence. This W-type radiation tube is ingeniously designed for excellence in continuous annealing, galvanized wire horizontal annealing furnaces, and silicon steel heat treatment furnaces. It operates within a protective atmosphere enhanced with nitrogen and hydrogen, harnessing the formidable heat generated by natural gas or coke oven gas combustion. This radiation tube ensures rapid and uniform heating of strip steel from ambient temperature to an impressive 900 degrees Celsius, facilitating optimal annealing through superior radiation heat transfer from the outer tube. This exceptional product epitomizes efficiency and precision, rendering it indispensable for your sophisticated heat treatment needs.
