The straight tube of the W-type radiation tube is engineered from high-temperature resistant centrifugally cast pit tube, a beacon of our dedication to durability and superior quality. Our bent tube, crafted with precision casting technology, stands as a testament to cutting-edge manufacturing excellence. The W-type radiation tube is precisely designed for applications in continuous annealing, galvanized wire horizontal annealing furnaces, and silicon steel heat treatment furnaces. Within a protective atmosphere rich in nitrogen and hydrogen, this extraordinary radiation tube effectively harnesses the immense heat energy produced by natural gas or coke oven gas combustion. It efficiently achieves swift and uniform heating of strip steel from ambient temperatures to an impressive 900 degrees Celsius, ensuring optimal annealing through exceptional radiation heat transfer from the outer tube. This outstanding product embodies both efficiency and precision, making it an invaluable solution for your heat treatment needs.
