Expertly engineered with painstaking precision, the straight tube of the W-type radiation tube shines with its impressive high-temperature resistance, thanks to its centrifugal casting from top-notch pit tube materials. The bent tube, showcasing the pinnacle of precision casting technology, enhances this ground-breaking design. The W-type radiation tube is indispensable in continuous annealing processes, galvanized wire horizontal annealing furnaces, and cutting-edge silicon steel heat treatment furnaces. Within a protective atmosphere rich in nitrogen and hydrogen, this trailblazing radiation tube captures thermal energy from the combustion of natural gas or coke oven gas. It ensures that strip steel is heated swiftly and uniformly from ambient temperatures to a remarkable 900 degrees Celsius. This rapid and even heating is crucial for the flawless annealing of strip steel, setting unparalleled benchmarks in industrial mastery.
