For years, the steel sector has grappled with universal challenges: excessive alloy consumption, unstable product quality, environmental pressures, and the gap between high-end supply and demand. Our team at CISRI has developed targeted solutions that deliver tangible value across the entire production chain.
🔧 Core Technological Advantages
✅ Graded Aerosol Cooling System (Internationally Leading): A game-changer replacing traditional water quenching with precision segmented cooling and tempering. It reduces vanadium consumption by 20-40% (eliminating resource waste) while solving the long-standing issue of surface rust—critical for end-users in construction and infrastructure. Adaptable to both new and retrofitted production lines (from standard bars to high-speed wire rods), this technology is officially recognized in China’s national energy-saving technology catalog and has won 3 provincial-level science & technology awards.
✅ Stabilized Nitrogen Addition & Precipitate Control: Optimizes the nitrogen-vanadium (N/V) atomic ratio to 0.5-1.0, forming fine, uniform V(C,N) precipitates (10-50nm) that enhance strength and toughness without increasing alloy costs. This breakthrough ensures consistent mechanical properties, with yield strength predictions accurate to ±20MPa (85% precision) and ±30MPa (90% precision) via our proprietary process model.
✅ Dual Low-Temperature Rolling + Graded Cooling: Integrates low-temperature heating, roughing, and finishing with graded cooling to refine grain structure and pearlite lamellae. This minimizes cross-sectional property variation—addressing a major pain point for large-size bar applications in heavy machinery and engineering.
✅ High-Penetration Rolling & Homogenization Technology: Solves core porosity, segregation, and insufficient deformation in heavy-section bars (a common issue in traditional rolling). By optimizing heating temperatures and reduction schedules, it improves core-to-surface uniformity, reducing low-temperature impact performance failures.
✅ High-Strength, Weather-Resistant & Fatigue-Resistant Steel Series: Industrialized production of HRB600E/700E/800E and weather-resistant (NH) grades, with yield strength ranging from 600MPa to 800MPa. These steels meet strict seismic (strong 屈比 ≥1.25), corrosion-resistant, and fatigue requirements—ideal for high-stress applications like automotive suspensions, bridge construction, and offshore structures.
✅ Annealing-Free Cold Heading Steel: Eliminates the energy-intensive spheroidizing annealing process via controlled rolling/cooling and pearlite morphology control. This cuts production time, reduces energy consumption, and lowers equipment investment for fastener manufacturers.
🚀 Tangible Outcomes & Global Impact
• Cost Reduction: $3-9 per ton in alloy savings, with partner enterprises saving over 200 million RMB (≈$28M) in total alloy costs over 3 years. For HRB500E production, vanadium content is reduced by 0.02-0.04%, driving significant material efficiency.
• Quality & Reliability: National inspection failure rates dropped from 7% (2021) to 4.7% (2023). The graded aerosol cooling system enhances surface corrosion resistance—no large-scale rust in open air for 1 month, reducing end-user rejections and downtime.
• Sustainability & Efficiency: Energy-saving processes have been integrated into 2 pilot lines and 3 full-scale demonstration lines (partnering with leading steelmakers in China), supporting global low-carbon manufacturing goals while boosting production capacity.
• Market Expansion: Our high-performance steels now serve critical sectors worldwide, from automotive crankshafts and rail turnout components to offshore oil drilling tools—filling the gap in high-value special steel supply.
• Technical Leadership: Beyond awards, our technologies are licensed to steel producers across Asia, with ongoing collaborations to adapt solutions for European and North American manufacturing standards.
These innovations aren’t just about incremental improvements—they’re about redefining what’s possible for the steel industry: cost-effective, high-quality, and environmentally responsible production that meets the demands of tomorrow’s advanced manufacturing.
We’re actively seeking global partners—steel producers, end-users, and research institutions—to co-develop next-generation solutions for green, intelligent, and high-performance steel.
