Recently, our factory has steadily progressed on a project to manufacture rotary kiln drums for a Southeast Asian customer's cement plant. The rolling process has been successfully completed and the core welding phase has officially begun. As a core component of critical cement plant equipment, the machining accuracy of this rotary kiln cylinder directly impacts its operating efficiency and service life. Our factory strictly adheres to the refined process standards for the entire process: "rolling → welding → rounding → machining → inspection."
During the initial rolling process, the technical team employed a CNC plate rolling machine for precise rolling, ensuring the cylinder's curvature met design parameters, laying a solid foundation for subsequent welding. The current welding process utilizes submerged arc automatic welding technology, combined with specialized welding materials. Certified senior welders are employed to control weld profile, penetration, and weld distortion to ensure weld strength and sealing.
Subsequently, the drums will undergo a rounding process, where specialized equipment will correct minor deformations from welding. Machining will then proceed to precisely finish the cylinder's ports and connections. Finally, it will undergo a multi-dimensional inspection process, including non-destructive testing and dimensional accuracy testing, to ensure that the product meets the technical requirements of Southeast Asian customers. The smooth progress of this project demonstrates our factory's technical strength and extensive experience in machining large pressure vessel components.
