1. Reheating and Descaling

Hot-rolled coils undergo a comprehensive pickling process, where high-performance scale breakers and hydrochloric acid solutions effectively remove surface scale and oxide layers. This process eliminates potential surface defects and ensures a clean, uniform surface for subsequent cold rolling operations.

2. Rough Rolling

During the rough rolling stage, descaled slabs are processed into intermediate strips with precisely controlled shape, thickness, and width. Equipped with advanced Automatic Width Control (AWC) technology, the roughing mill’s entry and exit edgers accurately regulate strip width, ensuring dimensional consistency and stable product quality throughout the rolling process.

3. Finishing Rolling

The finishing rolling process precisely adjusts the thickness, width, and profile of steel coils to meet specified customer requirements while achieving excellent surface quality and dimensional accuracy at the targeted finishing temperature. SHOUYUAN utilizes advanced equipment, including Work Roll Shift Mills, Pair Cross Mills, and On-line Roll Grinders (ORG), to optimize productivity, improve strip shape control, and enhance the overall quality of finished coils through precise crown control technology.

4. Run-Out Table Cooling and Coiling

After passing through the finishing mill, steel strips are transported onto the run-out table for controlled cooling and coiling. Through optimized water-cooling technology, the strips are rapidly cooled to the appropriate coiling temperature, ensuring stable metallurgical properties and consistent coil quality.
