Key Growth Drivers

Rising Demand for Ferroalloys in Steelmaking

Global steel production continues to expand, especially in Asia-Pacific and Latin America, creating strong demand for ferroalloys such as ferromanganese, ferrochrome, and ferrosilicon. Submerged arc furnaces (SAFs) are the preferred technology for bulk ferroalloy production due to their high energy efficiency and suitability for continuous large-scale operations. Rapid infrastructure growth and automotive manufacturing in countries like China and India boost steel consumption, indirectly accelerating SAF installations. Additionally, the shift toward electric arc furnace (EAF)-based steelmaking further strengthens SAF demand, as ferroalloys are essential additives in EAF operations. Government-backed infrastructure development projects and growing renewable energy capacity also push alloy demand, especially in wind and solar energy components.

• For instance, Tata Steel sources ferromanganese and ferrosilicon from SAF-based units supporting crude steel capacity above 35 million tons per year.

Expansion of Silicon Metal Applications

Silicon metal is gaining significant traction in solar photovoltaics, semiconductors, aluminum alloys, and lithium-ion batteries. Submerged arc furnaces remain essential for converting quartz and carbonaceous materials into metallurgical-grade silicon. The global solar energy transition drives consistent silicon consumption for photovoltaic cells, especially in China, which dominates the solar manufacturing chain. Rising electric vehicle (EV) adoption also boosts demand for silicon-enhanced aluminum and battery components. With governments worldwide supporting decarbonization goals, investments in silicon metal capacity are surging, translating to higher furnace demand. SAFs’ ability to operate continuously at high temperatures with minimal operational interruptions makes them ideal for large-volume silicon metal production.

• For instance, Elkem’s Salten plant in Norway operates submerged arc furnaces converting quartz to metallurgical silicon for photovoltaic use. Solar manufacturing growth lifts silicon

Industrialization in Emerging Economies

Emerging markets in Southeast Asia, Africa, and South America are witnessing a wave of industrialization across mining, metallurgy, and infrastructure sectors. This structural transformation increases demand for ferroalloys, calcium carbide, and fused minerals, directly impacting SAF adoption. Local governments support industrial clusters and special economic zones with incentives for downstream processing. Countries rich in mineral reserves, such as South Africa (manganese) and Brazil (bauxite), invest in value addition within their borders. Submerged arc furnaces provide a cost-effective method for converting raw ores into higher-value intermediate products. Furthermore, the need for self-sufficiency in metal and chemical production encourages regional players to deploy SAFs in new processing plants.

Key Trends & Opportunities

Shift Toward Energy-Efficient and Digital SAFs

Manufacturers increasingly adopt advanced submerged arc furnaces equipped with digital monitoring, real-time data analysis, and automated control systems. These smart SAFs improve productivity, reduce electrode consumption, and enhance safety. Energy optimization features like waste heat recovery and variable frequency drives gain popularity amid rising energy prices and stricter environmental regulations. European and Japanese companies lead innovation in green and energy-efficient SAFs, while developing nations explore retrofit opportunities. As decarbonization pressure rises, operators seek technologies that reduce specific energy consumption without compromising output. This digital transition presents a clear opportunity for OEMs offering automation-ready and eco-friendly SAF solutions.

• For instance, SMS group has deployed digital SAF control platforms that enable continuous tracking of furnace current, voltage, and electrode position across furnaces rated above 90 MVA.

Vertical Integration by Ferroalloy Producers

Major ferroalloy producers are increasingly investing in integrated operations, including mining, smelting, and downstream alloy processing. This trend boosts demand for in-house SAF installations to improve supply chain control and reduce reliance on third-party processors. Companies in China, India, and the Middle East are leading this push, using SAFs to ensure consistent quality and cost control across operations. Vertical integration also helps producers respond faster to market fluctuations and regulatory changes. By investing in customized furnace solutions, operators can optimize output for specific alloy grades, opening opportunities for specialized SAF system suppliers and engineering firms.

Key Challenges

High Capital and Operational Costs

Submerged arc furnaces require significant upfront investment in infrastructure, refractory materials, and power systems. For many small and medium enterprises (SMEs), the capital intensity remains a major barrier. Operational costs are also high, particularly due to large electricity requirements and periodic maintenance. Fluctuations in electrode pricing and raw material costs further impact profitability. Regions with high power tariffs face slower SAF adoption, especially in non-integrated facilities. Additionally, environmental compliance—such as fume collection and waste handling—adds to overall cost. These financial hurdles restrict entry of new players and delay upgrades of older furnace units.

Environmental and Regulatory Pressure

Submerged arc furnace operations emit significant levels of dust, CO₂, and other particulates, especially when processing carbon-rich feedstock. With tightening emission norms and industrial decarbonization goals, operators face growing regulatory pressure to invest in cleaner technologies and pollution control systems. Compliance often requires expensive upgrades, such as advanced baghouse filters and off-gas treatment systems. In regions with strict environmental norms like the EU, older furnaces are being phased out or retrofitted. For new entrants or operators in developing countries, balancing cost with regulatory demands remains a key challenge that affects the overall growth pace of the market.
