The first stage of CRCA manufacturing includes acid cleaning the Hot-rolled Steel Coil. It begins by immersing the metal in acid to dissolve surface oxides and impurities. Subsequently, thorough rinsing eliminates any remaining acid residues and contaminants. To prevent rust formation, the cleaned metal surface is coated with oil. This meticulous treatment ensures the preparation of clean, rust-resistant steel coils. Acid cleaning lays the foundation for achieving the desired product quality and performance. The process sequence is crucial for subsequent manufacturing stages. The CRCA process begins with pickling hot rolled carbon steel in an HCL continuous pickling line, removing oxide scales via hydrochloric acid treatment. Subsequently, the steel undergoes cold rolling in a sophisticated Cold Rolling Complex equipped with a 1500mm & 1250mm width 6Hi Rolling Mill with AGC and 4Hi Skin Pass. The cold rolling stage reduces thickness and enhances surface finish, controlled by AGC for precision. Following cold rolling, the steel coils enter a Batch Annealing Furnace (BAF) for annealing, tempering internal stresses, and improving ductility. Our product range includes HR Pickled, HR Pickled Skin Pass, CR Full Hard, CR Bake/Semi Hard & CRCA Steel Coils, tailored to diverse commercial and automotive needs. This meticulous process, coupled with quality assurance measures, ensures the production of high-quality CRCA steel coils meeting stringent industry standards.
This ensures better paint adhesion, which in turn helps prevent rust formation on the end applications. the same technology enhances the visual appearance of the finished product. Additionally, with better paint, the aesthetics of the finished product are enhanced.
