75 Ferro Silicon Alloy As Deoxidizer For Steelmaking Casting Lump 50mm-100mm
Ferrosilicon Description
Ferrosilicon is one type of ferrosilicon product, mainly lumps, which are easier to store than ferrosilicon powder. The silicon in ferrosilicon blocks has a good affinity with oxygen and is often used as a deoxidizer. In fact, it can also be used as an indolent and spheroidizing agent in the cast iron industry.
Used as inoculant and spheroidizer in cast iron industry. Cast iron is an important metal material in modern industry. It is cheaper than steel and easy to be melted and smelted. It has excellent casting properties and much better shockability than steel, especially nodular cast iron whose mechanical properties reach or approach those of steel. Adding a certain amount of ferrosilicon in cast iron can prevent the formation of carbide in iron and promote the precipitation and spheroidization of graphite, so ferrosilicon is an important inoculant and spheroidizing agent in the production of ductile iron. Used as reducing agent in ferroalloy production. Not only the chemical affinity between silicon and oxygen is great, but also the high silicon iron has low carbon content. Therefore, high silicon ferrosilicon is a kind of reducing agent commonly used in the production of low carbon ferroalloy in ferroalloy industry.
Ferrosilicon Applications:
1. Ferro Silicon Alloy is used in steelmaking and foundries as a source of silicon in production of carbon steels, stainless steels, and other ferrous alloys for its deoxidizing properties, to prevent loss of carbon from the molten steel (so called blocking the heat); ferromanganese, spiegeleisen, silicon calcium, and many other materials are used for the same purpose
2. Ferro Silicon Alloy can be used to make other ferroalloys.Ferro Silicon Alloy is also sed for manufacture of silicon, corrosion-resistant and high-temperature resistant ferrous silicon alloys, and silicon steel for electromotors and transformer cores. In manufacture of cast iron, ferrosilicon is used for inoculation of the iron to accelerate graphitization. In arc welding, ferrosilicon can be found in some electrode coatings.
3. Ferro Silicons Alloya is for manufacture of prealloys like magnesium ferrosilicon (FeSiMg), used for modification of melted malleable iron; FeSiMg contains between 3-42% of magnesium and small amounts of rare earth metals. Ferro Silicon Alloy
also important as an additive to cast irons for controlling the initial content of silicon.
