The amount of use should be determined according to the actual situation, which has a great relationship with the raw iron and molten iron after melting, and should be adjusted according to the actual situation:
In general, the addition amount of gray cast iron ferrosilicon particles is 0.2~0.5%.
For nodular cast iron, ferrosilicon particles are generally added in an amount of 0.5~1.1%.
For cast iron horizontal continuous casting ductile iron, the general addition amount of ferrosilicon particles is 0.8~1.5%.
Packing of ferrosilicon grain manufacturers: tons of bags or according to customer requirements.
