Project Background
Hebei Iron & Steel Group Jinding Heavy Industry Co., Ltd. is a large-scale, comprehensive steel enterprise integrating ironmaking, steelmaking, rolling, and casting. The client possesses robust production capabilities and top-tier heavy equipment—including a 1,080m³ blast furnace, a 120-ton converter, and large-scale continuous casting and rolling mills—with an annual output exceeding 2 million tons each for pig iron and steel billets. Within its vast, full-chain production line, a stable and reliable ventilation system serves as the lifeline ensuring maximum production capacity and safe operation.
Application Scenarios and Challenges
The operating conditions in steel smelting and casting workshops are extremely harsh. Processes such as blast furnace ironmaking, refining furnace steelmaking, and large-scale sand mixing generate massive amounts of dust and gases at extreme temperatures. The client urgently required high-power dust collection blowers and industrial forced draft fans capable of withstanding wear and high temperatures for these critical operational stages.
Due to the continuous nature of heavy industrial production, the equipment must endure rigorous challenges—including extremely high dust concentrations, physical erosion from high-temperature particles, and heavy-load operation—as any unplanned downtime would result in massive economic losses for the entire production line.
Yutong Solutions and Core Advantages
Faced with such stringent supplier selection criteria, Yutong Blower successfully passed every level of evaluation—thanks to its mature manufacturing processes, solid technical credentials, and highly cost-effective customized solutions—to become a long-term strategic partner of Jinding Heavy Industry, delivering multiple sets of heavy-duty centrifugal fans tailored for their core production lines.
During project execution, Yutong demonstrated engineering advantages specifically suited to the metallurgical industry:
- High-Temperature and Heavy-Duty Anti-Wear Design: To address the high-temperature exhaust gases and furnace dust found in iron and steel plants, we custom-engineered heavy-duty, high-temperature exhaust fans. By utilizing special heat-resistant alloys, thickened forward-curved or backward-curved blades, and proprietary wear-resistant liner structures, the fans perfectly withstand the physical erosion caused by metallurgical dust and the stresses of thermal expansion.
- Precision Aerodynamic Matching and Cost Reduction: Tailoring the solution to the specific high-pressure and airflow requirements of Jinding Heavy Industry’s equipment—such as a 1,080 m³ blast furnace and a 2,500 mm medium plate rolling mill—Yutong’s fluid dynamics team conducted precise aerodynamic selection and matching. This approach ensured powerful suction and forced air delivery while avoiding the inefficiency of “oversized equipment for small loads,” thereby significantly reducing motor power consumption.
Value Created for the Customer
The integration of Yutong blowers not only provides a reliable power foundation for Jinding Heavy Industry’s continuous production but also perfectly aligns with the client’s strategic vision of becoming a “resource-efficient and environment-friendly” enterprise. By supplying equipment characterized by high operational efficiency and long maintenance-free intervals, we have substantially lowered the client’s total costs regarding procurement and long-term operation and maintenance. Today, Yutong’s high-performance fans operate reliably and consistently across the client’s major production sites, serving as a robust support system for this steel giant in its pursuit of cost reduction, efficiency gains, and green development.
