Low aluminum ferrosilicon is an kind of ferroalloy composed of iron and silicon. It is commonly used in the steelmaking industry as deoxidizer and alloying agent. Compared with ordinary ferrosilicon, low Al Ferrosilicon contains lower aluminum elements.
The aluminum content of low aluminum ferrosilicon is usually below 1.0. According to different requirements, the aluminum content can reach lower levels, such as 0.5, 0.2, 0.1 or less, etc. Low Al FeSi is more suitable in some specific applications. For example, as a deoxidizer and alloying agent in the steelmaking industry, the aluminum content needs to keep at a low level to avoid affecting the composition of the steel. At the same time, it also plays a important role as an alloying element additive to improve the properties of steel.
In addition to the steelmaking industry, it is a good inoculant and spheroidizing agent in the cast iron industry. It prevents iron from forming carbides and promotes graphite precipitation and spheroidization, thereby improving the properties of cast iron.
Overall, low aluminum ferro silicon plays an important role in the steel and cast iron industries, improving the quality and performance of materials. It is a commonly used ferrous alloy that is widely used in different industrial fields.
