Product Description

1, Production process description
According to the actual production situation of industrial silicon electric furnace with capacity above 25500kva in China, it is suggested that the whole coal smelting process should be selected as the smelting process.
1.Principle of industrial silicon production
In the submerged arc furnace, using the heat energy converted by electric energy, silica and carbonaceous reductant react to produce industrial silicon.The reaction process is relatively complex, which can be simply expressed as SiO2 + 2C = Si + 2CO
