Description

Technical Field

[0001] The utility model relates to the field of a mixing device for ferrosilicon production which is convenient for screening, in particular to a mixing device for ferrosilicon production which is convenient for screening. Background Art

[0002] Ferrosilicon is an iron alloy composed of iron and silicon. Ferrosilicon is an iron-silicon alloy made by smelting in an electric furnace with coke, steel scraps, and quartz (or silica) as raw materials. Since silicon and oxygen can easily combine to form silicon dioxide, ferrosilicon is often used as a deoxidizer in steelmaking. At the same time, since a large amount of heat is released when SiO2 is generated, it is also beneficial to increase the temperature of molten steel while deoxidizing. At the same time, ferrosilicon can also be used as an alloying element additive and is widely used in low-alloy structural steel, spring steel, bearing steel, heat-resistant steel and electrical silicon steel. Ferrosilicon is often used as a reducing agent in ferroalloy production and the chemical industry. Ferrosilicon is made of coke, steel scraps, and quartz (or silica) as raw materials and smelted in an electric furnace. When ferrosilicon is traditionally smelted, silicon is reduced from silica containing SIO2. Most ferrosilicon smelting uses metallurgical coke as a reducing agent, and steel scraps are a regulator for ferrosilicon.
