Smelting Of Ferrosilicon

Ferrosilicon is made from coke, steel scrap, quartz (or silica) and smelted by electric furnace. In traditional smelting of ferrosilicon, silicon is reduced from silica containing SIO2. Metallurgical coke is mostly used as a reducing agent for smelting ferrosilicon, and steel scrap is a regulator for ferrosilicon.

Production of one ton of ferrosilicon raw materials and electricity consumption are:

Silica: 1780-1850kg

Coke: 890-930kg

Steel chips: 220-230kg

Electrode paste: 45-55kg

Power consumption: 8400-9000kwh/t
