Ferrosilicon 75 is commonly used as a deoxidizer in the steelmaking process, added to molten steel to remove oxygen and other impurities. It also increases the strength and hardness of steel, making it more suitable for use in heavy engineering applications.
In addition to its use in steelmaking, ferrosilicon is also used to produce cast iron, which is used in the manufacture of a wide range of products such as pipes, automotive parts, and machinery. Adding ferrosilicon to molten cast iron improves its fluidity and reduces the likelihood of the cast iron reacting with impurities in the melt.

Quality Control
To ensure the best and most stable quality, we check more than four times for one order by spectrometer and chemical test, including raw materials, production, and final products.
X-Ray Fluorescence Spectrometer
A ray Fluorescence Spectrometer can radiate X-rays according to different chemical elements, It can detect energy and wavelength by different chemical elements. The software can transfer them into data for all kinds of chemical composition.
Features:
Immediate analysis: quality tests only take 5 minutes.Physical analysis method that won't cause chemical reaction in the testing process. High precision and high sensibility Save time to make samples. Allow samples as solid, liquid, and powder shapes.
