company news about Ferrosilicon smelting operations: power supply and charge

Power supply in front of furnace

Ferrosilicon is generally produced in a submerged arc furnace using a continuous operation method. The current input from the transformer enters the furnace filled with charge through the electrode. During the entire smelting process, the electrode is always deeply and steadily inserted into the charge without exposing the arc. The smelting process relies on the arc generated by the current passing through the electrode and the charge. Thermal and resistance heating are continued.

Charge distribution

During the ferrosilicon smelting process, a large amount of hot furnace gas will be generated in the furnace. In order to make full use of the energy of the hot furnace gas, maintain good permeability of the charge, accelerate the chemical reaction in the furnace, increase the furnace temperature, and expand the "crucible" , the material surface should be distributed in a wide and flat cone shape.

Controlling the appropriate material surface height, especially controlling the height of the large material surface and maintaining a wide and flat cone, are issues that must always be paid attention to in actual operations.
