On April 17, 2026, Fushun Special Steel Co., Ltd. announced the official launch of China's first smart high-alloy sheet production line. This 520 million yuan investment integrates six processes: hot rolling, cold rolling, heat treatment, pickling, thick plate finishing, and thin plate finishing, with an annual designed capacity of 8,000 tons, marking a new level of domestic high-end alloy sheet supply capability.
Technical Breakthrough: AI-Enabled Full Process Control
This production line adopts internationally advanced automation control systems, equipped with thickness automatic control (AGC) systems, work roll bending devices, and high-precision X-ray thickness gauges, width gauges, and other testing instruments. The centralized control center uses an integrated management platform to achieve full-process tracking, tracing, and management of quality, materials, efficiency, and energy consumption.
The system features AI intelligent control functions with multiple mathematical models that enable real-time measurement and correction of rolling force, temperature, thickness, and other parameters. This closed-loop control not only improves product dimensional accuracy but also significantly enhances production efficiency. Factory director Zhao Baojie explained that all processes achieve fully automatic loading/unloading, ensuring zero surface scratches and collision damage.
Material Upgrade: Supporting High-End Equipment Manufacturing
High-alloy sheets serve as key fundamental materials for high-end equipment manufacturing, widely used in aerospace, energy and chemical engineering, marine engineering, rail transit, and other key fields. Previously, domestic high-end high-alloy profiles and sheets relied on imports to some extent; this production line will effectively alleviate this situation.
The line can produce full-series high-temperature alloys, corrosion-resistant alloys, stainless steel, titanium alloys, ultra-high-strength steel, tool steel, and other high-value-added products. Among these, high-temperature alloy sheets are indispensable in core components like aero-engine blades and combustion chambers; corrosion-resistant alloy sheets are key materials for marine engineering equipment.
Precision Machining: Complete Chain from Material to Parts
High-alloy sheets are just the starting point; the core of the value chain lies in transforming materials into precision parts. Taking sheets produced by Fushun Special Steel as an example, processing them into aero-engine components, precision hydraulic valve blocks, and robot joint structural parts requires extremely high machining accuracy and process stability.
This is exactly the field where Hold-Tech Precision Industrial excels. We specialize in high-precision CNC machining services, equipped with five-axis machining centers, turn-mill composite centers, and other advanced equipment, capable of processing various high-alloy sheets and profiles into precision parts with tolerances controlled within ±0.01mm. We have accumulated rich cutting parameter databases and process experience for difficult-to-machine materials like high-temperature alloys and titanium alloys.
Collaborative Innovation: Deep Integration of Materials and Processing
The launch of Fushun Special Steel's smart production line provides a stable, high-quality raw material supply chain for downstream precision manufacturing enterprises. As an extension of the industry chain, Hold-Tech transforms these high-end materials into functional components required by customers through precision machining technology.
In the new energy vehicle sector, battery tray structural parts processed from high-strength steel plates require guaranteed dimensional accuracy and welding flatness; in the semiconductor equipment field, stainless steel plates become vacuum chambers and reaction chamber components after precision machining, with stringent requirements for surface roughness and cleanliness. These all require perfect matching of material performance and processing technology.
Future Outlook: Collaborative Evolution of High-End Manufacturing
Fushun Special Steel's chief engineer Li Tao stated that this production line has reached the domestic first-class level in smart production management. As a downstream precision machining enterprise, we are also advancing digital workshop construction, implementing traceability throughout the entire production process through MES systems.
From intelligent breakthroughs at the material level to precision deepening at the processing level, China's high-end manufacturing is forming a complete innovation chain. Hold-Tech will continue to deepen technical collaboration with upstream material enterprises, providing customers with more reliable and efficient precision parts solutions.
