Selected Success Story

Energy Steward Project at JINNAN STEEL GROUP

Domestic pioneering energy steward model launch as a green, low-carbon demonstration and resource utilization benchmark.

Plant & Process

JINNAN STEEL GROUP (Shanxi, China) is an integrated steel producer with a complete steel rolling process. The project focuses on the reheating furnace and 5th caster soaking pit.

"Jointly implemented by SOUTH TECHNOLOGY, DONGMING GREEN ENERGY, and JINNAN STEEL GROUP to build a green, low-carbon demonstration project."

AI Integration

Full-process thermal management powered by proprietary AI algorithms.

Safe Operation

Long-term steward service ensuring 24/7 reliability and performance monitoring.

Technical Scope

  • Full-fiber furnace roof retrofit

    Total replacement of traditional roof with high-efficiency fiber lining to minimize thermal inertia.

  • Intelligent reheating control

    End-to-end optimization from caster exit to furnace exit, ensuring precise temperature uniformity.

  • High-Emissivity functional coatings

    Applied on critical furnace lining areas to reduce oxidation scale and protect refractory surfaces.

Project Performance Targets

Benchmarks aligned with T80 Extreme Efficiency standards

7-15%
Target Fuel Saving

Per ton of steel, based on T80 extreme efficiency benchmarks for reheating furnaces.

5-15%
Scale Loss Reduction

Significant decrease in surface metal loss due to atmosphere control.

0.1-0.3%
Yield Improvement

Incremental gain in saleable material across the entire reheating process.

Benchmark Achievement

Engineered to achieve high-efficiency resource utilization benchmarks.

Note on performance:

The exact performance depends on each plant's baseline and process, but the project is designed and implemented to meet or exceed T80-level performance benchmarks established by the China Iron and Steel Association.
