Crafted with unparalleled precision and meticulous attention to detail, the straight tube of the W-type radiation tube is engineered to withstand the most extreme temperatures. These tubes, centrifugally cast from premium pit tube materials, represent the pinnacle of high-temperature resistance technology. The bent tube, an exemplar of precision casting, seamlessly complements this innovative design. This W-type radiation tube is indispensable in high-demand applications such as continuous annealing processes, galvanized wire horizontal annealing furnaces, and sophisticated silicon steel heat treatment furnaces. Operating within a nitrogen and hydrogen-rich protective atmosphere, this advanced radiation tube expertly captures the thermal energy from natural gas or coke oven gas combustion. This ensures a swift and even heating of strip steel from ambient temperatures up to an awe-inspiring 900 degrees Celsius. This rapid and consistent heating process is paramount in achieving flawless annealing of strip steel, setting unsurpassed standards in industrial excellence.
