Your North American Smelting Pain Points, Solved
Skyrocketing electricity prices (fueled by competition with tech giants for power resources)superscript:3, strict EPA Title 40 particulate matter (PM) and opacity limits,superscript:2, high electrode consumption, and stagnant productivity—your aging AC EAF is holding you back. YND’s AC-to-DC retrofit addresses every core challenge, with solutions engineered for North America’s unique energy and compliance landscape.
Why YND’s AC-to-DC Retrofit Stands Out
We’re not just a furnace manufacturer—we’re a 20+ year DC EAF specialist with 40+ patented technologies, in-house R&D, and a track record of 920+ global successful projects. Our retrofit solutions draw on China’s high-speed rail DC drive technology, with a full end-to-end process: on-site plant assessment → customized design → precision retrofitting → post-install technical support. We control every step to ensure minimal downtime and maximum ROI for your North American operation.superscript:1
The North American Smelter’s ROI: What You Gain
Forget empty claims—we deliver measurable, bottom-line benefits tailored to your biggest costs and compliance needs:
✅ Slash Energy & Electrode Costs
Cut electricity consumption by 20% and electrode costs by 35%—critical for beating North America’s soaring power prices. Our DC system boasts a natural power factor of 0.95-0.98, no reactive power compensation devices needed—eliminate extra equipment and maintenance costs, and outcompete in a tight energy market.superscript:3
✅ Meet EPA Title 40 Compliance Effortlessly
Our closed-loop DC smelting process reduces PM emissions to ≤0.0052 gr/dscf and opacity to ≤6%, fully aligning with EPA Title 40’s strict EAF emissions rules. Achieve green smelting without costly add-on emission control systems—future-proof your plant for North America’s growing sustainability mandates.superscript:2superscript:4
✅ 20% Higher Productivity, No Major Renovation
Stable, uninterrupted arc and gap-free melting boost production efficiency by 20%. Our retrofit adapts to your existing plant layout and capacity (50kVA to 30,000kVA customizable), saving floor space and avoiding costly downtime from full facility overhauls.
✅ Grid-Friendly Operation, Zero Interference
Our DC drive technology eliminates power grid interference—no more production disruptions or compliance issues from unstable power supply, a top pain point for North American smelters competing for limited energy resources.superscript:3
