A key market highlight is the dominance of AC Submerged Arc Furnaces, which are expected to account for 53.1% of global revenue in 2025. Their continued leadership is attributed to lower maintenance requirements, long electrode life, and high thermal stability, making them ideal for large-scale alloy melting. In parallel, DC furnace variants are gaining gradual acceptance in applications requiring precise temperature control and reduced electrode consumption.
The strongest demand driver remains the ferroalloy segment, which is projected to hold 49.7% market share in 2025. Increasing global steel consumption across construction, automotive, shipbuilding, and engineering sectors is generating sustained need for ferrochrome, ferromanganese, and ferrosilicon. Submerged arc furnaces offer superior smelting performance for these alloys due to efficient submerged arc energy transfer, high smelting capacity, and accurate raw material feeding systems.
