Case Study: Air‑Suspended Blowers Empower the Steel Industry to Reduce Costs and Carbon Emissions in Guangdong’s JFE Energy‑Saving Retrofit Project

Preface

Under the dual‑carbon policy framework, the steel industry—being a key sector with high energy consumption—faces an urgent need to upgrade equipment for energy efficiency and pursue refined cost‑reduction and consumption‑cutting measures as essential drivers of high‑quality development. Conventional fan systems typically suffer from high energy use, excessive noise, cumbersome maintenance, and poor operational stability, which over time drive up production and operating costs and hinder the transition to green, low‑carbon practices.

This time Guangzhou JFE Steel Plate Co., Ltd. The wind turbine energy-saving retrofit project, by Guizhou AVIC Huaqiang Technology Co., Ltd. Throughout the project, we provided comprehensive equipment support and a one-stop retrofit solution, upgrading aging facilities by replacing them with high-performance air‑suspension blowers. Upon implementation, the project delivered substantial reductions in energy consumption, lower operation and maintenance costs, and enhanced production stability, establishing a benchmark for energy‑efficient industrial blower retrofits in the steel industry.

01 Project Overview & Renovation Background

Project Unit Guangzhou JFE Steel Plate Co., Ltd.

Equipment Supply and Technical Support Guizhou AVIC Huaqiang Technology Co., Ltd.

Core equipment : Air‑suspended centrifugal blower (one unit replaces multiple units)

Original intention of the renovation The existing fan units supporting the JFE steel plate production line in Guangzhou are conventional, aging equipment that, after prolonged operation, have revealed numerous industry‑wide issues: energy consumption remains stubbornly high, driving up electricity costs year after year; operating noise is excessive and vibration is severe, resulting in a poor workshop environment; component wear is rapid, with frequent breakdowns, leading to cumbersome routine maintenance and substantial operational expenses; and overall equipment stability is inadequate, adversely affecting the continuous, efficient operation of the production line and failing to meet the enterprise’s needs for green manufacturing, cost reduction, and efficiency improvement.

To optimize the production system, reduce overall energy consumption, and alleviate operational and maintenance burdens, the company decided to launch a dedicated energy‑saving retrofit project for its blowers. Following multiple rounds of technical comparisons and solution evaluations, it ultimately selected the comprehensive energy‑saving retrofit方案 based on AVIC Huaqiang’s air‑suspension blowers.

02 End-to-End Expertise | On-site Survey + Technical Coordination, Customized Renovation Solutions

High-quality renovation results stem from proactive, meticulous technical support. In the early stages of the project, the AVIC Huaqiang technical team conducted an in-depth on-site assessment at JFE’s steel plate production facility in Guangzhou, delivering comprehensive, professional services. Technical exchanges and on-site surveys at the construction site 。

Drawing on core data—including plant‑floor production line operating conditions, existing fan specifications, ductwork layouts, operating durations, and load requirements—technical experts systematically identified the operational pain points of aging equipment, precisely quantified energy‑saving potential, and engaged in multiple rounds of in‑depth collaboration with the enterprise’s production managers and technical team. They tailored equipment selection, installation layouts, and commissioning plans to address specific needs, mitigate retrofit risks, and ensure the solutions’ suitability, feasibility, and practical implementation, thereby laying a solid foundation for subsequent renovation work, stable equipment operation, and efficient energy savings.

03 A comprehensive before-and-after comparison—tangible results are evident.

Following the completion of this project, which involved the full replacement and upgrade of all aging wind turbines, the equipment’s operational performance, energy‑consumption metrics, O&M costs, and production environment have all been comprehensively optimized. The improvements before and after the retrofit are striking, with tangible, measurable results in both energy savings and quality enhancement.

[Before Transformation: High Energy Consumption, Low Efficiency, and Complicated Operations & Maintenance]

The existing conventional fan equipment suffers from high energy consumption, and its prolonged operation at full load keeps electricity costs persistently high. Its mechanical structure is complex, resulting in significant vibration and excessive noise that degrade the workshop’s working environment. Wear‑prone components such as bearings and impellers require frequent replacement, necessitating regular shutdowns for maintenance and parts changes—processes that not only consume substantial manpower and resources but also disrupt continuous production line operation. Consequently, overall operational efficiency is low, and total lifecycle maintenance costs are high, making the equipment incompatible with low‑carbon manufacturing requirements.

[After renovation: energy-saving, quiet, stable, and low-consumption]

Following the commissioning of the new blower, which incorporates AVIC Huaqiang’s proprietary air‑suspension technology, the equipment has been seamlessly integrated with the plant’s production load, delivering stable operation and highly efficient, precise performance. Compared with conventional units, it achieves a substantial reduction in overall energy consumption, resulting in significant power savings and resource efficiency. With no mechanical contact or wear, the system exhibits minimal vibration and low noise levels, comprehensively enhancing the workshop’s production environment. It also requires infrequent maintenance, features very few consumable parts, and substantially lowers labor‑intensive O&M costs and downtime losses, ensuring reliable round‑the‑clock operation and perfectly meeting the continuous, high‑intensity production demands of steel enterprises.
