Ferrosilicon is an ferro aloi terutamanya used in steel production as a penyahoksida dan aloi bahan tambahan. The standard model of ferrosilicon is usually expressed as the percentage of silicon content and iron content. Common standard models include:
Ferrosilicon 65 (silikon content is about 65%, Iron content is about the balance)
Ferrosilicon 68 (silikon content is about 68%, iron content is about the balance)
Ferrosilicon 72 (silikon content is about 72%, Iron content is about the balance)
Ferrosilicon 75 (silikon content is about 75%, Iron content is about the balance)

As for why ferrosilicon 70 is not a common standard model, there may be the following reasons:
Pengeluaran proses dan teknikal batasan: The ratio of silicon content to iron content of Ferrosilicon 70 may cause technical challenges or uneconomical aspects of the production process.
Low market demand: Compared with common models, the market demand for ferrosilicon 70 may be low, so manufacturers are reluctant to include it in the standard model range.
Ketidakpatuhan dengan spesifikasi: Ferrosilicon 70 may not meet the requirements of relevant standards or specifications and is therefore not included in the standard model range.
Walaupun ferrosilicon 70 is not a common standard model, in actual production, it can still be customized according to customer needs. This requires manufacturers to carry out special preparation and process optimization according to customer requirements to ensure the production of products that meet the requirements.
