A New Method Of Ferrosilicon Production. ferrosilicon 75, fesi 72, and fesi 70 for steelmaking.

How is ferrosilicon produced? Ferrosilicon is an important alloy material widely used in steelmaking, casting, electronics, and other industries. This article will introduce the production process of ferrosilicon, including the preparation of main raw materials and furnace materials, the smelting process, cooling treatment, and packaging of finished products. ferrosilicon I. Preparation of Raw Materials The main raw materials for ferrosilicon production are metallic silicon and blast furnace slag. Metallic silicon is a very pure form of silicon, typically produced through ore reduction, electric furnace reduction, or silane chemical methods. Blast furnace slag is a byproduct of steelmaking, containing large amounts of iron, silicon, calcium, and other elements. In order to improve the quality of ferrosilicon, a certain amount of calcium silicon alloy and aluminum powder alloy need to be added. II. Preparation of Furnace Materials The metallic silicon, blast furnace slag, calcium sili
