Steel rolls play a crucial role in the manufacturing of tank heads, which are the rounded or curved ends of cylindrical tanks. The process of manufacturing tank heads involves forming flat steel plates into the desired shape through a combination of techniques including rolling, pressing, and welding. The manufacturing process can vary based on the specific requirements of the tank and the industry standards in place. Steel rolls, along with other machinery and techniques, are essential in achieving the precise curvature and structural integrity required for tank heads used in various applications. EUROLLS likely manufactures rolls used in shaping and forming these tank heads.
