Note：
1. Consumption of Coke is dry weight
2. The consumption of silica, coke and power is calculated on the base of producing one ton of FeSi 75%
3. The output is calculated in according to cos∮0.75
3. Size of raw materials
Silica Quartz: 40-120㎜
Coke: 5-15㎜
Steel scraps: ＜100㎜（Fe75% powder）
Semi-coke: 5-18㎜
4. Physical& chemical specifications
Silica Quartz: SO2＞97% Al2O3≤0.85 P2O5＜0.02%, clean surface and high heat stability;
Coke: fixed carbon ＞80%, ash ≤14%;
Steel scrap: carbon steel with Fe＞95%
