The Submerged Arc Furnace (SAF) is the core smelting unit in ferroalloy plants, forming the central stage of the ore preparation – SAF smelting – casting or crushing production route. It is specifically designed for high-temperature reduction reactions and directly determines alloy yield, power consumption, and production stability.
Yeneng Submerged Arc Furnaces are widely applied for the production of:
Silicon Manganese (SiMn)
Ferro Manganese (FeMn)
Ferro Silicon (FeSi)
Ferro Chrome (FeCr)
Ferro Nickel (FeNi)
Silicon Metal
These alloys are essential raw materials for carbon steel, stainless steel, alloy steel, and special steel production, as well as for chemical and metallurgical industries.
III. Technical Features:
Submerged Electrode Operation
Deep electrode penetration ensures stable arc behavior, uniform heat distribution, and efficient reduction reactions within the furnace burden.
Robust Furnace Structure
The furnace adopts a heavy-duty steel shell with high-quality refractory lining and selective water-cooled components, ensuring long campaign life under continuous high-temperature operation.
Flexible Furnace Configuration
Open, semi-closed, or closed furnace designs can be provided according to alloy type, raw material characteristics, and environmental requirements.
Stable Electrical System
The furnace is equipped with a high-capacity transformer, reliable electrode regulation system, and optimized short network, ensuring stable power input and low electrical losses.
Efficient Off-Gas Collection
Closed and semi-closed designs enable effective off-gas capture and dust collection, supporting environmental compliance and optional energy recovery.
Automation & Process Control
PLC-based control systems allow real-time monitoring of electrical parameters, electrode position, and furnace operation, improving process stability and operational safety.

IV. Main Components of Submerged Arc Furnace
