PRODUCT CENTER
It is used as an inoculant and a nodularizing agent in the cast iron industry. Cast iron is an important metal material in modern industry. It is cheaper than steel, easy to melt and smelt, has excellent casting properties and much better shock resistance than steel. Especially ductile iron, its mechanical properties are comparable or close to steel. Adding a certain amount of ferrosilicon to cast iron can prevent the formation of carbides in iron and promote the precipitation and spheroidization of graphite. Therefore, in the production of ductile iron, ferrosilicon is an important inoculant (helps to precipitate graphite) and nodularizer.

Among these uses, the steelmaking, foundry and ferroalloy industries are users of ferrosilicon. Together they consume about 90% of the ferrosilicon. Among various grades of ferrosilicon, 75% ferrosilicon is widely used at present. In the steelmaking industry, 3-5 kg of 75% ferrosilicon is consumed per ton of steel produced.

Silicon-manganese alloy is an alloy composed of manganese, silicon, iron and a small amount of carbon and other elements. Silicon-manganese alloy is mainly used as the intermediate material of deoxidizer and alloying agent in iron and steel production, and also the main raw material of medium and low carbon ferromanganese production. Silicon-manganese alloys can also be smelted in continuous operation in large, medium and small submerged arc furnaces.

Steel industry: Ferromanganese is an indispensable deoxidizer and desulfurizer in the steelmaking industry. Good steel needs to be deoxidized and desulfurized during smelting, and the use of deoxidizers will greatly increase its cost. Therefore, ferromanganese is a cheap deoxidizer. Desulfurization refers to the removal of harmful substances such as sulfur in steel. ferromanganese can well achieve the purpose of desulfurization, effectively reduce the content of harmful elements in steel, and improve the quality of steel.
