RAMON INTELLIGENCE FOR YOUR INTELLIGENT MANUFACTURING
Continuous Casting Machine No. 4 of the Steelmaking Plant was commissioned on October 9, 2008. As the only slab continuous casting machine of Zhongnan Iron & Steel, it has an annual billet production capacity of 1.65 million tons.
The production line is capable of manufacturing more than 200 steel grades across nine major product categories, including carbon structural steel, low-alloy structural steel, shipbuilding steel, alloy tool steel, high-quality carbon structural steel, high-strength steel, bridge steel, pressure vessel steel, and pipeline steel.
The existing eddy-current mold level control system suffered from poor operational stability, high spare-parts costs, and aging equipment that was difficult to maintain.
In addition, several high-intensity manual operations remained in place, resulting in significant labor demands.
Frequent mold replacement shutdowns also led to low equipment utilization and increased maintenance workload.
Safety Benefits: Robotic operations replace manual work in hazardous areas, significantly reducing safety risks and creating a safer working environment.
Social and Brand Benefits: Intelligent production line equipment reduces energy consumption, improves slab quality, and enhances corporate brand value.
Improved ladle slag detection sensitivity reduces residual steel by approximately 100 kg per heat, generating annual cost savings of RMB 1.46 million.
Generates annual economic benefits of RMB 2.75 million by improving continuous casting efficiency, reducing auxiliary material consumption, and minimizing head and tail slab losses.
The system enables unmanned casting platform operations and optimized workforce allocation. By reducing one operator per shift across four shifts, it saves RMB 450,000 in annual labor costs while significantly reducing manual workload. Current platform operations are remotely monitored by one operator from the central control room.
① Improved Quality and Production Efficiency
The system features high-precision molten steel level detection, fast response, and strong anti-interference capability.
It improves slab quality, reduces downgraded slabs, and achieves a ±3 mm level control accuracy hit rate of over 99%, improving accuracy by 2%.
By reducing downgraded slab production, the system can generate annual economic benefits of approximately RMB 2.592 million.
② Reduced Head Slab Scrap Loss
During the automatic casting start process, the system rapidly stabilizes molten steel level control, reducing the length of transitional slabs by more than 0.5 meters per casting sequence.
Based on 593 automatic casting starts per year, the system can reduce transitional slab waste and generate economic benefits of approximately RMB 1.838 million annually.
