Meticulously engineered with precision, the resilient straight tube of the W-type radiation tube is crafted from superior pit tube materials through centrifugal casting, boasting unmatched high-temperature resistance. Complementing this is the bent tube, a testament to precision casting technology, forming a groundbreaking design. The W-type radiation tube is indispensable in continuous annealing processes, galvanized wire horizontal annealing furnaces, and sophisticated silicon steel heat treatment furnaces. Operating within a specially controlled nitrogen and hydrogen-rich protective atmosphere, this avant-garde radiation tube utilizes thermal energy generated from natural gas or coke oven gas combustion. It ensures the strip steel is rapidly and uniformly heated from ambient temperatures to a remarkable 900 degrees Celsius. This swift, even heating is crucial for the ideal annealing of strip steel, setting unprecedented standards in industrial excellence.
