Core Technology Breakthroughs for DC Electric Arc Furnaces: Leap from Pain Points to Highlights

Leveraging China’s high-speed rail DC drive technology, YND DC Electric Arc Furnace improves arc stability by 50%, completely resolving the chronic issues of “arc drift and frequent arc interruption” plaguing AC furnaces. Boasting a natural power factor as high as 0.95–0.98, it eliminates the need for additional reactive power compensation devices, directly cutting electricity consumption by 20%. For a 2000kVA unit alone, this translates to annual electricity cost savings of over RMB 1 million. Meanwhile, submerged arc smelting reduces electrode oxidation, extending electrode service life by 35% and slashing consumable costs by 35%. Every kilowatt-hour of electricity and every electrode is optimized to deliver maximum value.

With precise temperature regulation up to 3,000℃, the furnace maintains a consistent, stable temperature in the molten pool, keeping the metal burnout rate ≤ 3%—a stark contrast to the 8–10% rate seen in traditional AC furnaces. Recovery rates of rare metals exceed 98%. Whether for ensuring composition precision in steel smelting or maximizing resource utilization in non-ferrous metal recycling, it meets the demands of high-end production, empowering enterprises to capture the high-value market segment.

The equipment can withstand grid voltage fluctuations of ±10%, making it suitable for complex industrial power environments. Equipped with high-speed rail-grade core components, it reduces equipment failure rates by 40% and cuts annual maintenance costs by 25%, supporting 24/7 uninterrupted production. Eliminating the need for frequent furnace shutdowns and adjustments, it boosts production capacity by 20%, making it ideal for large-scale mass production scenarios.

The short-process smelting method reduces carbon emissions per ton of steel by 60%, aligning perfectly with the “dual carbon” policy goals. Its enclosed arc design minimizes unorganized flue gas and dust emissions, lowering smoke concentration by 40%. For hazardous waste treatment applications, it achieves 100% harmless disposal, ensuring seamless passage of environmental compliance inspections and freeing enterprises from the risk of environmental penalties.
