Low Aluminum Silicon Iron/ferrosilicon/Ferro Silicon72#73#75#

An iron alloy composed of iron, iron, and silicon (using silica, steel, and coke as raw materials, and silicon reduced at a high temperature of 1500 to 1800 degrees Celsius is melted into molten iron to form a ferrosilicon alloy). It is an important alloy variety in the smelting industry.

The ferro silicon we provide (FeSi72~FeSi75,FeSi40, FeSi65, FeSi70) series,The thickness of FeSi72~FeSi75 series ferrosilicon ingots produced by iron mold casting shall not exceed 100mm; the thickness of FeSi40, FeSi65, FeSi70 ingots shall not exceed 80mm, or the ferrosilicon shall adopt direct molding casting process, and the segregation of silicon content shall not exceed 3.0%. . When ferrosilicon is supplied in lump, granular or powder form, the particle size should comply with the following table:

	specification/mm
