Crafted with extraordinary precision and care, the straight tube of the W-type radiation tube stands as a testament to high-temperature resistance. Made through centrifugal casting from top-tier pit tube materials, it is a marvel in thermal engineering. Complementing it is the bent tube, an epitome of precision casting technology, rounding off this remarkable design. This W-type radiation tube is indispensable in continuous annealing processes, galvanized wire horizontal annealing furnaces, and the highly sophisticated silicon steel heat treatment furnaces. Operated within a protective atmosphere enriched with nitrogen and hydrogen, this avant-garde radiation tube efficiently capitalizes on thermal energy generated from natural gas or coke oven gas combustion. This ensures a swift and even ascent of the strip steel's temperature from ambient levels to a striking 900 degrees Celsius. Such rapid and uniform heating is crucial for the ideal annealing of strip steel, setting unprecedented benchmarks in industrial excellence.
