Expertly crafted with the utmost precision, the straight tube of the W-type radiation tube showcases remarkable high-temperature resilience. This is achieved through centrifugal casting using top-tier pit tube materials. The bent tube, another testament to our advanced precision casting technology, completes this groundbreaking design. The W-type radiation tube is indispensable in continuous annealing processes, galvanized wire horizontal annealing furnaces, and the advanced silicon steel heat treatment furnaces. Operating within a nitrogen and hydrogen-rich protective atmosphere, this innovative tube harnesses thermal energy from natural or coke oven gas combustion. This guarantees the swift and uniform heating of strip steel, elevating temperature from ambient to an impressive 900 degrees Celsius. This rapid, even heating is pivotal for achieving flawless strip steel annealing, setting new benchmarks for industrial excellence.
