Low carbon ferromanganese refining electric arc furnaces are high-efficiency, low-carbon metallurgical equipment tailored for the production of low carbon ferromanganese alloys—a key additive for manufacturing high-strength, corrosion-resistant steel products.
The furnace adopts the electrosilicothermic process as its core refining technology. It generates an ultra-high temperature environment of 1600–1800℃ through arc discharge between electrodes. Raw materials including manganese ore, ferrosilicon alloy, and lime are charged into the furnace. Ferrosilicon acts as a reducing agent to convert manganese oxides in the ore into metallic manganese, while lime adjusts the slag system to enhance manganese recovery and reduce impurity content.
- Magnesite Refractory Lining
The furnace lining is constructed with high-purity magnesite materials, which have excellent corrosion resistance and high-temperature stability, effectively withstanding the erosion of molten manganese-iron alloy and slag during long-term smelting.
- Stable Electrode System
The electrode system is a core component of the furnace. It ensures continuous and stable arc discharge to maintain the high temperature required for smelting. The electrode material and installation structure are optimized to reduce energy loss and improve power utilization efficiency.
- Low-carbon & Eco-friendly: No carbon-based reducing agents such as coke are needed, which fundamentally reduces carbon emissions during the smelting process and meets green production requirements.
- High Energy Efficiency: Advanced process optimization reduces power consumption from the conventional 2000 kWh/ton to about 690 kWh/ton, significantly lowering production costs.
- High Product Quality: The precise temperature control and stable reaction environment ensure that the carbon content of the produced low carbon ferromanganese can be stably controlled below 0.5%, with low impurity content and uniform composition.
Below are the core technical parameters of industrial - scale low carbon ferromanganese refining electric arc furnaces, with a typical 6300 KVA model as the reference basis:
- Parameters vary with furnace capacity and process route; the optimized silicothermic process has significantly lower power consumption and shorter cycles.
- Slag basicity and raw material ratio can be adjusted to improve manganese recovery rate, which is generally ≥90% for advanced processes.
