Against the backdrop of global supply chain restructuring, the advancement of carbon neutrality goals, and the U.S. strategy for critical mineral autonomy, core U.S. industries such as metallurgy, mining, environmental protection, and new energy are facing an urgent need for transformation and upgrading: the steel industry needs to break free from its reliance on imported high-end ferroalloys, the mining sector urgently needs to solve the problem of efficient utilization of low-grade ores, the environmental protection industry needs to respond to increasingly stringent new hazardous waste disposal regulations, and the new energy industry needs to build a local core material supply chain. Backed by more than 20 years of smelting technology accumulation and 37 core patents, the YND DC Submerged Arc Furnace (DC SAF) accurately targets the pain points of the U.S. market. With its core advantages of energy efficiency, wide raw material adaptability, environmental compliance, and intelligent controllability, it is deeply integrated into six high-value application scenarios in the United States, becoming a strategic equipment for promoting U.S. industrial upgrading and ensuring supply chain security.
The core competitiveness of the YND DC Submerged Arc Furnace lies in its dual characteristics of “technological advantages aligned with local needs and product performance adapted to policy orientations” — compared with traditional AC submerged arc furnaces and similar competitors, its core indicators of more than 20% energy saving, ±5℃ precision temperature control, and over 98% metal recovery rate perfectly meet the core demands of U.S. industry for “cost reduction, compliance, autonomy, and low carbon”. Moreover, its modular design, minimally invasive retrofitting capability, and full-lifecycle localized services have further eliminated U.S. enterprises’ concerns about imported equipment, achieving in-depth integration of technological value and market demand. Below, we detail the product advantages and implementation value of the YND DC Submerged Arc Furnace in combination with core U.S. application scenarios.
Deeply Cultivating the Rigid Demand for Large-Scale Ferroalloy Production, Solving the Dilemma of Import Dependence on U.S. High-End Raw Materials
The U.S. steel industry is dominated by scrap-based steelmaking (scrap accounts for 51% of total steel production), and electric arc furnace steelmaking accounts for more than 70% of crude steel output. However, the dependence on imported high-end ferroalloys is as high as 90%, and the import of core raw materials has become a key bottleneck restricting the development of the industry. The YND DC Submerged Arc Furnace, with large-scale, high-quality ferroalloy production as its core application scenario, has become the core choice for the upgrading of U.S. steel enterprises.
In terms of product advantages, the YND DC Submerged Arc Furnace reduces electrode consumption by 35%, controls alloy composition deviation within 0.5%, and can achieve 24/7 uninterrupted operation, perfectly matching the large-scale production needs of top U.S. steelmakers such as Nucor and Nippon Steel-US Steel. At the same time, it has extremely strong raw material adaptability and can efficiently process low-grade iron concentrate from the Minnesota iron ore base and nickel-cobalt ore from Michigan without fine beneficiation pretreatment, significantly reducing enterprises’ raw material procurement costs. Currently, this scenario has become the core rigid demand field of the YND DC Submerged Arc Furnace in the United States, helping U.S. steel enterprises gradually get rid of their dependence on imported ferrochrome, ferronickel, and ferrovanadium, and promoting the localized layout of the ferroalloy industry.
Adapting to New Hazardous Waste Disposal Regulations, Achieving a Win-Win of Environmental Compliance and Resource Utilization
With the implementation of the U.S. Environmental Protection Agency (EPA)’s 2026 Hazardous Waste Permit New Regulations, and the increasingly stringent regional environmental policies including California’s AB32 Carbon Neutrality Act and the Electric Reliability Council of Texas (ERCOT) rules, U.S. steel, chemical and mining enterprises are facing soaring hazardous waste disposal costs and significant non-compliance risks. The YND DC Submerged Arc Furnace (DC SAF) is positioned for the harmless treatment and resource utilization of industrial hazardous and solid waste, delivering the dual goals of compliance + profitability for enterprises.
Its hermetically sealed furnace body design, integrated with a high-efficiency flue gas capture system, reduces dust emissions by 40% and enables 100% harmless conversion of hazardous wastes such as steelmaking sludge, heavy metal-contaminated soil and polychlorinated biphenyls (PCBs). Eliminating the need for additional environmental upgrade facilities, it helps enterprises cut compliance investment by 40% and avoid a maximum of $250,000 in daily non-compliance fines. More notably, the slag generated after treatment meets the American Society for Testing and Materials (ASTM) C989 standard and can be recycled as construction aggregate, realizing the transformation of waste into raw materials and creating additional revenue for enterprises. Ideally suited for the needs of hazardous waste-concentrated regions like the U.S. Great Lakes Industrial Zone and California’s chemical parks, it has emerged as the optimal solution for enterprises to address the new environmental regulations.
