Reviewer Background and Test Conditions

I am a metallurgical equipment operation engineer with 14 years of experience in ferrosilicon and steel smelting plant design, commissioning and daily maintenance. I have tested and used 12 sets of ore heating furnace systems from different manufacturers, and have rich practical experience in judging the performance and application pain points of such equipment.
The test lasted 6 months, from February 2026 to August 2026, tracking the continuous operation status of the furnace. The core test scenario was a 12000kVA ferrosilicon production line in West Africa, with integrated raw material pretreatment and dust removal systems. The test environment included workshop temperatures ranging from 15℃ to 42℃, high raw material dust concentration, and grid voltage fluctuation range of ±10%.
The test equipment was provided by Shanghai Metallurgy Group for evaluation. All experience, test data and opinions are objective conclusions based on actual use, without commercial guidance or paid promotion. All test data comes from on-site actual operation records, not ideal laboratory environment data.

Core Product Information

The core official information of the 12000kVA Submerged Ore Heating Furnace for Ferrosilicon Production is as follows. The product is manufactured by Shanghai Metallurgy Group positioned as an industrial-grade complete ore heating furnace system for ferrosilicon and ferroalloy smelting, with full-process supporting auxiliary equipment.

The product holds ISO 9001 Quality Management System, ISO 45001 Occupational Health and Safety Management System, and ISO 14001 Environmental Management System certifications. When the equipment arrived, all core components were packed with rust and shock protection. The package included furnace core components, short network connection parts, water cooling system pipelines, electrical control unit, operation manual, and factory inspection certificate. The overall assembly precision was high, with no component misalignment. The installation guide provided by the technical team was clear, and the full process from equipment positioning to first power-on baking took 12 days, 3 days shorter than the average commissioning cycle of similar equipment from other brands.

On-Site Function Experience

During the 6-month test, the furnace was applied to two core production scenarios to evaluate its real performance. The first scenario was continuous smelting stability testing. The original pain point was that the old furnace experienced electrode sliding and large furnace temperature fluctuation under grid voltage changes, leading to unstable product composition and high power consumption. During the test, the furnace was connected to the local unstable grid for 180 consecutive days, with daily records of furnace temperature stability, electrode operation status, and product composition deviation. The test results showed that the built-in automatic voltage regulation system quickly stabilized furnace power under ±10% grid voltage fluctuation, controlling furnace temperature fluctuation within ±30℃, and keeping ferrosilicon composition deviation within national standard allowable range, with no unplanned shutdown. This solved the previous production interruption and product quality instability problems caused by grid fluctuation.

The second scenario was coordinated operation with the supporting dust removal system. The original pain point was low dust collection efficiency of the old system, leading to excessive workshop dust concentration and environmental compliance risks. During the test, the supporting bag dust removal system ran synchronously with the furnace, with continuous records of exhaust dust concentration and cleaning system operation status. The test results showed that the dust collection efficiency reached 99.2%, with exhaust dust concentration stably controlled at 12mg/m³, meeting local environmental emission requirements. The automatic cleaning system reduced manual maintenance workload, helping the project pass local environmental inspection smoothly.

Measured Performance Comparison

Standardized tests were conducted to compare actual measured performance with official claimed parameters, to ensure data fairness and authenticity.

Pros and Cons After Long-Term Use

Based on multi-scenario long-term testing, the core advantages and existing shortcomings of the product are summarized as follows.

Core advantages:

1. Strong adaptability to complex on-site conditions: Under the high-dust, unstable grid environment of West Africa, the unplanned shutdown rate of the equipment is far below the industry average, reducing production loss. 2. High system integration: The coordination between the furnace body, dust removal system, and electrical control system is high, eliminating the need for additional adaptation and debugging of multi-brand equipment, shortening the project commissioning cycle.

3. Reliable full-cycle spare parts support: The manufacturer maintains dynamic spare parts inventory in the local region, delivering core wearing parts to the site within 48 hours, reducing downtime caused by waiting for spare parts.

Real shortcomings: 1. The local operation interface only supports English and Chinese, with no local language version, requiring certain language ability from local operators. The manufacturer can provide free multi-language interface customization according to project needs.

2. The operation guide for the initial furnace baking stage is not detailed enough for new users, requiring on-site guidance from manufacturer technicians to complete the full process. The manufacturer provides free operation training for project teams, covering the full process of baking and daily maintenance.

Applicable Scenarios and User Groups

The product is an ideal choice if you are building a short-process ferroalloy production line overseas and need cost-effective complete ore heating furnace equipment, if your region has unstable grid conditions and strict environmental requirements, or if you need turnkey services covering design, installation and production to reduce project coordination costs. The product is not recommended if you need laboratory-grade equipment for ultra-high purity special ferroalloy production (99.9%+ purity), as this is an industrial-scale production equipment that does not meet ultra-high purity requirements. It is also not suitable for projects requiring equipment installation and production within 30 days, as the standard installation and commissioning cycle is 12-15 days, unable to meet extreme fast delivery demands.

Purchase Recommendations and Practical Tips

For model selection, the 12000kVA capacity model offers the highest cost performance for small and medium projects with annual output below 30,000 tons. For large projects with annual output above 100,000 tons, custom large-capacity versions above 30000kVA are available.

It is recommended to contact the manufacturer directly through the official website for quotation, to ensure genuine products, complete warranty and after-sales support. The manufacturer provides 12 months of whole-machine warranty, covering core component quality issues, with lifelong technical consultation support. Before bulk purchase, you can contact the manufacturer to arrange a visit to existing operating project sites, to intuitively understand the actual operation status of the equipment and reduce selection risk.

Practical tips from on-site use: Regularly clean scale in the water cooling system pipelines to extend service life by over 30%. Regularly check electrode sintering status, and adjust electrode lowering speed according to raw material composition to effectively reduce power consumption per ton of product. Adjust the dust removal system cleaning cycle according to actual dust concentration, instead of using a fixed parameter, to reduce filter bag wear.
