As the EPC contractor of the project, CERI actively addressed the construction requirements for "high yield and efficiency, low carbon and environmental protection, and intelligent manufacturing". By embodying the spirit of craftsmanship and utilizing mature, reliable, and advanced technical equipment, CERI implemented scientific project management and comprehensive services. This approach ensured excellence in quality, efficiency, cost, and environmental protection, positioning the project as a leading demonstration production line for special steel products both domestically and internationally.

Delivering excellence in quality

High-standard dimensional accuracy: CERI's sixth-generation high-rigidity short-stress path rolling mill and three-roll reducing and sizing mill are used to improve the dimensional accuracy of products.

High-standard mechanical properties: The rolling permeability is improved by using the technology of large reduction of breaking down mills, and the advanced processes of discontinuous holding rolling and rolling/cooling control are applied to fulfill temperature/rolling/cooling control of the full rolling line and improve the inherent structural and mechanical properties of products.

High-standard surface quality: The ultra-high-pressure water descaling device is used to remove scale on the surface; the anti-scratch design is fully adopted for mechanical equipment; the online profiler and surface detector are used to monitor real-time surface quality.

Delivering excellence in efficiency

Efficient process: The reducing and sizing technology is applied to realize free-size rolling, simplify the pass system, reduce the number of spare parts for rolls and guides, and improve the rolling operation rate.

Efficient operation: A series of advanced equipment has been provided, such as robots for automatic identification of billet codes, automatic detection of out-of-squareness slabs and curvature as well as automatic sampling for rotary shear, robots for laser marking, robots for nameplate welding and unmanned overhead traveling cranes, to improve the automatic operation level and response speed of the full cycle of the production line.

Efficient management and control: An integrated centralized control center equipped with hyper-convergence and a KVM agent system is built to deeply converge, monitor, analyze and optimize the big data of the whole workshop, build a factory based on digital twins, and fulfill lean management and control.

Delivering excellence in cost

Low metal consumption: Large-tonnage slabs are used, and intelligent and optimized multiple-length shearing is applied, so as to reduce the loss in top/end cropping and improve the yield; mature intelligent furnace technology is adopted to reduce oxidation-caused burning loss.

Low energy consumption: Insulation vehicles are used to transport hot slabs to reduce fuel consumption; energy-saving equipment, motors and hydraulic systems with the potential energy recovery function are selected to reduce the power consumption of production lines.

Low labor cost: Mature intelligent manufacturing technology and equipment are applied to reduce the staffing for production lines.

Delivering excellence in environmental protection

For the heating furnace, the advanced flue gas blowback system, intelligent combustion system and low-nitrogen combustion burner are adopted to reduce the emission of carbon monoxide and nitrogen oxide.

The rolling mill area, abrasive-disk cutter area and finishing area are equipped with fume exhaust and dust removal systems to eliminate the environmental pollution caused by harmful substances, meet the ultra-low emission requirements and improve the operating environment.

All self-produced steam is recycled, and the water system has a high circulation rate, building a modern green factory.
