Ferrosilicon Furnace Smelting Process
01
Ferro silicon metal furnace is a closed, environmentally friendly and energy-saving solution for ferrosilicon smelting production. Preheating of ferrosilicon furnace can eliminate water and volatile components, thereby stabilizing smelting process conditions and reducing the unit energy consumption of the furnace.
02
Water spraying on the shell of ferrosilicon furnace and forced ventilation at the bottom of the furnace ensure effective cooling. The heat-conducting carbon lining combined with effective cooling forms a spontaneous freezing layer on the hot surface of the lining, which minimizes lining erosion and improves thermal efficiency.
03
The characteristics of ferro silicon metal submerged arc furnace are the use of carbon or magnesium refractory materials as linings and self-training electrodes.
04
The electrode is inserted into the charge for submerged arc operation, using the energy of the arc and the current passing through the charge, and the energy generated by the resistance of the charge to melt the metal, adding materials one after another, and discharging iron slag intermittently, and operating continuously.
05
The load of the ferrosilicon furnace transformer is continuous and stable, with low impedance voltage, more voltage regulation levels, small step difference and strong overload capacity.
06
Ferrosilicon furnace can achieve extremely low unit energy consumption, low reducing agent and electrode consumption and very high production volume. The enclosed design also minimizes dust emissions into the factory environment and surrounding atmosphere.
