What kind of steel is used when smelting ferrosilicon balls

There are many ferrosilicon related products, such as ferrosilicon balls, ferrosilicon blocks, ferrosilicon powder, ferrosilicon particles, etc. However, there are many manufacturers engaged in ferrosilicon consumption and sales on the market today, and the market competition is also very fierce, as long as the quality of ferrosilicon is ensured, the talent has won the recognition of more users and lost its wide application. So how to smelt high-quality ferrosilicon, not only need to master the correct smelting method, but also need to control the raw materials of ferrosilicon. Steel is one of the raw materials for smelting ferrosilicon, so what kind of steel can be used to smelt high-quality ferrosilicon.

The iron in ferrosilicon is derived from the steel chips in the charge, according to the requirements of the quality of ferrosilicon, only ordinary carbon steel chips are allowed in smelting, and alloy steel chips are not allowed, such as stainless steel, high chromium, high manganese steel and so on. Therefore, smelting ferrosilicon such as alloy steel chips will form scrap. Pig iron filings should also not be used because of their high phosphorus content. Smelting ferrosilicon can not use non-ferrous metal chips such as copper, aluminum, etc. Therefore, in order to ensure the quality of ferrosilicon, only ordinary carbon steel chips are allowed in smelting. Steel chips with severe rust can not be used, because of its many impurities, iron content is not easy to control during smelting, and at the same time, the strength of steel chips with severe rust is poor, there are many powders, and the participation in the furnace affects the permeability of the material surface. Therefore, the iron content of the steel chips used in the rules is greater than 95%, and the appearance should be clean, and no obvious impurities are allowed. The length of the steel chips should not be too long to prevent uneven mixing and infarction of the lower pipe, and the overly long steel chips also make the charge over-charged unevenly, affecting the uneven three-phase load. For this reason, the length of regular steel chips is not more than 100 mm.
