As industrial enterprises grapple with the triple challenges of excessive energy consumption, non-compliant hazardous waste disposal, and low rare metal recovery rates, Anyang Younengde (YND) leverages 20 years of DC melting technology expertise and over 40 core patents to integrate China’s high-speed rail DC drive technology into plasma furnace R&D. The result? A full range of DC Plasma Furnaces spanning 50kVA to 30,000kVA – a game-changer for the steel, environmental protection, and non-ferrous metal industries.
1. High-Speed Rail-Grade Cutting-Edge Tech: Solving 3 Major Industry Pain Points
Backed by patents for stable DC plasma arc control (a core technology cluster), the equipment fundamentally addresses the industry’s longstanding issues of “arc drift, power grid interference, and high energy use”:
- Arc stability is 50% higher than traditional plasma furnaces. With precise control of ultra-high temperatures up to 3,000℃, metal burnout rate is reduced to under 3% (vs. the industry average of 8%-10% for conventional furnaces), while rare metal recovery rate exceeds 98%.
- Adopting China’s high-speed rail DC drive technology, the equipment cuts failure rates by 40% and annual maintenance costs by 25%. It remains stable even with ±10% grid voltage fluctuations, making it suitable for industrial plants with complex power conditions worldwide.
- Boasting a natural power factor of 0.95-0.98, no additional reactive power compensation devices are needed. A 500kVA unit deployed at a South Korean customer site reduced power grid interference complaints to zero, earning it the “Green Factory Supporting Equipment” certification locally.
2. Visible Energy Efficiency & Profits: Calculate Returns from Day One
No more vague claims of “energy savings” – real data quantifies the bottom-line impact:
- Lower Electricity Bills: Take a 2,000kVA hazardous waste treatment unit as an example. Based on an industrial electricity price of RMB 1/kWh (≈\(0.14/kWh) and 300 operating days annually, 20% energy savings translate to **288,000 kWh saved per year, cutting electricity costs by RMB 2.88 million (≈\)403,200)** .
- Reduced Consumable Costs: Electrode costs drop by 35%, and electrode lifespan extends by 35%. A tin dross processing plant reduced annual electrode expenses from RMB 1 million (≈\(140,000) to RMB 650,000 (≈\)91,000), while less frequent electrode replacements boosted annual production time by 10%.
- Waste-to-Resource Profits: For hazardous waste/metal scrap processing, the “harmless treatment + resource recovery” model delivers extra value. Processing 1 ton of circuit boards extracts 0.8g of gold and 20kg of copper – worth over RMB 500 (≈$70) in additional revenue per ton of waste.
3. Full-Scenario Customization: Tailored Solutions for Every Industry
From laboratory R&D to 10,000-ton scale production, from hazardous waste disposal to rare metal refining, the equipment adapts to all industrial needs:
- Hazardous Waste Treatment: 3,000℃ high temperatures fully decompose toxic organics in waste, achieving 100% harmless residue compliance with China’s Hazardous Waste Incineration Pollution Control Standards. Processing efficiency is 3x higher than traditional rotary kilns – a 2,000kVA unit handles 50 tons of hazardous waste daily.
- Rare Metal Extraction: Low-temperature melting prevents metal oxidation, pushing recovery rates of tungsten, molybdenum, and other precious metals to over 98% (vs. the industry average of 90%). A rare earth enterprise using a 630kVA unit for copper anode slime processing added RMB 8 million (≈$1.12 million) in annual rare metal revenue.
- Steel & Building Materials: Short-process melting cuts steel carbon emissions by 60% compared to traditional blast furnaces, aligning with the global trend of “EAF steel replacing converter steel”. It also reduces energy use by 20% for calcium aluminate and waste rock wool processing.
4. 20 Years of Expertise: More Than Just Selling Equipment
As China’s leading DC EAF vendor (backed by 920+ project cases), YND offers end-to-end support from process design to lifelong upgrades:
- Pre-Sales: Free on-site surveys and customized melting parameters based on raw material characteristics (e.g., hazardous waste composition, metal types). One auto dismantling plant received a full process design in just 7 days.
- Sales: An 80-person technical team provides on-site installation, commissioning, and operator training until independent operation is achieved – ensuring immediate production readiness.
- Post-Sales: 24/7 online support and on-site repairs within 12 hours. We guarantee “1-year free maintenance + lifelong technical upgrades”. A Henan customer’s 5-year-old equipment even received a free energy-saving control system upgrade, cutting electricity use by an extra 5%.
From 500kVA units exported to South Korea to 2,000kVA hazardous waste treatment projects domestically, from circuit board metal extraction to iron recovery from red mud – YND DC Plasma Furnaces prove with 40+ patents and 920+ cases that a high-quality melting furnace is not just a production tool, but a “core asset” for enterprises to reduce costs, increase efficiency, and achieve green transformation.
