Ferro pii fit ex coca, astula ferri, vicus (vel silica) ex ferro pii fornacis excoquunt.In ferrosilicon excoquunt traditum, silicon e silica continente SiO . minuitur2.Coke metallurgicae plerumque in ferrosilicon excoquunt ac reductae adhibentur, et laminae chalybea maxime ad mixtionem faciendam.
Materiae rudis et consumptio energiae electricae ad unum ton ferrosilicon producendum haec sunt:
- Silica vicus: 1780-1850kg
- Coke: 890-930kg
- Ferri micis: 220-230kg
- Electrode crustulum: 45-55kg
- Potentia consummatio: 8400-9000kwh / T
Generalis processus productionis excoquunt fornacei pii ferri, ut sequentia graphi ostendunt:
