What is the difference between 72# ferrosilicon and 75# ferrosilicon?

75# ferrosilicon is often referred to as 75A type ferrosilicon, and 72# ferrosilicon is often referred to as 75C type ferrosilicon. Generally speaking, the silicon content of 75# and 72# ferrosilicon in ferrosilicon is only 75% and 72%. 75 ferrosilicon is the so-called hard 75 with a silicon content of 74-80%, and 72 ferrosilicon is a soft 75 with a silicon content of 72-80%. At present, 72 ferrosilicon is commonly used in aluminum plants.

Iron is an essential deoxidizer in the steelmaking industry. In steelmaking, ferrosilicon is used for precipitation deoxidation and diffusion deoxidation. Brick iron is also used as an alloying agent in steelmaking. It is used as an inoculant and a nodularizing agent in the cast iron industry. In the production of ductile iron, 75 ferrosilicon is an important inoculant (helps to precipitate graphite) and spheroidizer. Used as a reducing agent in the production of ferroalloys. Not only the chemical affinity of silicon and oxygen is high, but the carbon content of high-silicon ferrosilicon is also very low. Therefore, high-silicon ferrosilicon (or siliceous alloys) is a commonly used reducing agent for the production of low-carbon ferroalloys in the ferroalloy industry. 75 Ferrosilicon is often used in the high-temperature smelting process of metal magnesium in the Pidgeon process of magnesium smelting. Replacing the magnesium in CaO.MgO consumes about 1.2 tons of ferrosilicon for every ton of metal magnesium produced. plays a big role. Other uses. Ground or atomized ferrosilicon powder can be used as a suspended phase in the beneficiation industry. It can be used as a coating for welding rods in the welding rod manufacturing industry. High-silicon ferrosilicon can be used in the chemical industry to manufacture products such as silica gel.
