1. Used as deoxidizer and alloy agent in steel making industry
2. Used as inoculant and spheroidizer in cast iron industry.
3. High silicon ferrosilicon powder or silicon alloy is used as reducing agent to produce low carbon ferroalloy in ferroalloy industry. Silicon iron powder added to cast iron can be used as inoculation agent for nodular cast iron, and can prevent the formation of carbide, promote the precipitation and spheroidization of graphite, and improve the properties of cast iron.
