2.3 Intelligent Equipment and Robotics
Steel enterprises are widely using intelligent equipment and industrial robots to replace workers in 3D (Dirty, Dangerous, Repetitive) positions. In the rolling mill workshop of Xiangtan Steel’s wire rod plant, a quality inspection system composed of 8 industrial cameras can conduct real-time 180-degree inspections of each coil, replacing traditional manual sampling inspections.
3. Transformation Results and Typical Cases
3.1 Xiangtan Steel: A Model of Digital Transformation
Xiangtan Steel’s digital transformation has achieved remarkable results. Through the construction of a smart factory, Xiangtan Steel has accomplished the following:
- Increased production efficiency by 30%, saved operational costs of 2.5 billion yuan, and generated direct economic benefits of 10 billion yuan.
- Streamlined and relocated over 1,000 personnel from harsh environment positions, significantly improving employee working conditions.
- Reduced the threshold for technological development, allowing technical personnel to perform modular operations like building blocks, transforming business knowledge into technical language.
Xiangtan Steel’s digital transformation extends beyond production to product development and quality control. The company has successfully developed high-end steels like nickel steel, which are used in global major projects such as large ship-borne LNG storage tanks.
3.2 Intelligent Transformation of Hebei Steel Enterprises
As China’s largest steel-producing province, Hebei’s steel enterprises have also seen significant results from digital transformation. By the end of 2024, over 80% of steel enterprises in Hebei had built intelligent control centers or applied large models.
