Cold rolling looper roll ultra-high-speed laser cladding

Taizhou Shandi Additive Manufacturing Co., Ltd., with the registered trademark "Shandi Additive," is dedicated to the research, development, and production of high-quality metal alloy powders. Serving both domestic and international markets, the company provides standard high-temperature alloy powders, mold steel powders, aluminum alloy powders, nickel-based self-fluxing alloy powders, cobalt-based alloy powders, amorphous alloy powders, brazing powders, iron-based alloy powders, metal-ceramic composite powders, and metal carbide composite powders, among others, for laser cladding alloy coating manufacturing and testing services.
As a critical component of rolling mills, the surface quality of cold rolling loop rolls significantly impacts the quality of steel production and operational efficiency. During the rolling process, these rolls are subjected to both cyclic and thermal stresses, leading to surface failures such as oxidation, cracking, wear, and even roll breakage. By employing ultra-high-speed laser cladding technology, alloy, ceramic, and composite cladding powders are treated with a laser beam, melting together with the surface metal of the cold rolling loop rolls to form a cladding layer with exceptional properties. This layer achieves a surface hardness of HRC65 or higher, ensuring excellent wear resistance, corrosion resistance, fatigue resistance, and high-temperature performance, thereby conserving valuable materials. Consequently, ultra-high-speed laser cladding technology is well-suited for the surface repair of rolls experiencing localized wear, impact, erosion, and oxidative corrosion.
