Products Description
Ferrosilicon is an ferro alloy that is commonly used as a deoxidizer and alloying additive in steel production. The grade of ferrosilicon is usually named according to the silicon content and carbon content, such as FeSi 72, where FeSi represents the chemical symbol of ferrosilicon and 72 represents the silicon content of ferrosilicon is 72%. Different manufacturers may have different grades, but ferrosilicon 72% usually refers to a ferrosilicon alloy containing 72% silicon. This ferrosilicon alloy has good deoxidation and alloying effects in steel smelting, and can improve the performance and quality of steel. In practical applications, it is necessary to select the appropriate ferrosilicon grade according to the specific process requirements and steel ingredients.

Application
In steel production
when smelting medium carbon steel, ferrosilicon needs to be added to the molten steel, which can effectively deoxidize and also serve as an alloying agent to improve the performance of the steel.
In casting production
when casting low-phosphorus and low-sulfur cast iron parts, ferrosilicon can be added as an inoculant to effectively promote the precipitation and spheroidization of graphite and improve the performance of cast iron.
Common forms of ferrosilicon
Ferro Silicon Lumps
Lumpy ferrosilicon usually includes natural ferrosilicon lumps and processed ferrosilicon lumps. The demand for ferrosilicon of 10-50mm is the largest, and the size can also be customized according to customer needs.
Ferro Silicon Particles
Granular ferrosilicon is obtained by processing ferrosilicon lumps. The size is usually in the range of 1-3mm, 3-10mm, etc. It can be customized according to needs.
Ferro Silicon Powder
Ferrosilicon powder is obtained after pulverization. The size of ferrosilicon powder is usually 320 mesh, 200 mesh, 60 mesh, 0.2mm, etc. Ferrosilicon powder can be deoxidized quickly, shortening the deoxidation time and reducing energy consumption.
Ferro Silicon Briquettes
Ferrosilicon briquettes are silicon and iron, which are byproducts of ferrosilicon alloy production through process processing, collection and pressing. The emergence of ferrosilicon briquettes reduces the cost of steelmaking and improves the deoxidation rate. Ferrosilicon briquettescan quickly adjust the trace iron elements in molten steel.
