VI. Project Details:
In 2022, Hongxin signed a contract with an Iranian client for an EPC turnkey project covering a single 33,000 kVA closed submerged arc furnace for silicomanganese alloy production. The scope of work was comprehensive, including detailed engineering design, manufacturing of all furnace equipment, procurement of auxiliary systems, on‑site installation, and full commissioning. Civil works were excluded from our scope and were handled by the client locally. Additionally, Hongxin provided technical guidance during the production ramp‑up phase to ensure that the furnace achieved its targeted output and quality metrics.
The closed furnace design was specifically chosen to meet the client’s requirements for energy efficiency, environmental compliance, and safe operation. Closed submerged arc furnaces allow for effective off‑gas capture and utilization, which is particularly important for silicomanganese production where proper fume handling improves both workplace conditions and process economics.
Despite the challenges of executing an overseas project during the post‑pandemic period – including logistics coordination, cross‑border travel restrictions, and on‑site adaptation – Hongxin’s project team successfully delivered the furnace on schedule. Following installation and cold commissioning, the furnace was started up and quickly reached stable operating conditions. The performance indicators, including power consumption per ton, alloy recovery rate, and product consistency, all met or exceeded the contractual guarantees.
After the furnace entered commercial production, the client reported consistently good operational results. The closed furnace design effectively minimized fugitive emissions while maintaining high thermal efficiency, leading to lower production costs compared to older open or semi‑closed furnaces in the region. The daily output and alloy quality have satisfied the client’s downstream steelmaking customers.
As a direct result of Hongxin’s successful delivery and the furnace’s strong performance, the owner has expressed full satisfaction with our work. Negotiations for a Phase II project have already commenced, which is expected to include additional furnaces and potentially an expanded scope of supply. This Iranian silicomanganese alloy project stands as a key international reference for Hongxin, demonstrating our capability to execute turnkey projects across borders and to build lasting customer relationships in the global ferroalloy industry.
