Ferrosilicon is an iron alloy composed of iron and silicon. It plays an important role in the metallurgical industry. Besides, in steelmaking, ferrosilicon is a deoxidizer and an additive for alloying elements. In the foundry industry, ferrosilicon 72 is a common deoxidizer and inoculator. Moreover, in the mineral processing industry, ferrosilicon acts as a weighting agent, and in welding rod production, it is a coating material. FeSi75, FeSi72, and Ferrosilicon 65 are common ferrosilicon models.
These different models of ferro silicon indicate that they have different silicon contents, for example: FeSi90 contains 87%-95% silicon. Ferrosilicon 75 contains 72%-80% silicon, which can be subdivided into three models: FeSi75A, FeSi75B, and FeSi75C. Ferro Silicon 65 contains 63%-68% silicon. FeSi45 contains 40%-47% silicon. FeSi15 contains 14-20% silicon. For the same reason, other impurity elements in various models of ferosilicon vary according to different uses.
Iron content of ferrosilicon 65: The iron content of FeSi 65 is usually around 30%. It may also contain small amounts of manganese, aluminum, calcium and other elements, and the specific content may vary according to different manufacturers and production processes. As a professional ferrosilicon manufacturer, the ferrosilicon produced by Anyang Highrise Metal Material Co., Ltd. strictly complies with national standards. That is to say, it has the characteristics of low sulfur, low phosphorus and low manganese.
Physical properties of ferrosilicon 65
The density of ferrosilicon 65 is usually between 7.2-7.8 g/cm3. Its melting point is about 1200℃, which makes ferro silicon 65 have good stability at high temperatures. The hardness of 65% FeSi is relatively high, usually between 150-200 HB, in fact it makes ferrosilicon 65 advantageous in some special fields. Ferro silicon 65 also has lower resistivity and higher thermal conductivity. At the same time, ferrosilicon 65 also has good oxidation resistance, acid and alkali resistance.
In fact, compared with FeSi75 and Ferrosilicon 72, the biggest advantage of FeSi 65 is the price. Its price is the lowest among the three. In steelmaking, FeSi65 can help users save time and labor resources spent in deoxidation of steelmaking. It can also be used as a replacement for FeSi 72 in castings. In short, Ferrosilicon 65 is a more cost-effective product and is a good choice for some customers in the metallurgical industry.
