Ferrochrome Silicon

Ferrochrome Silicon

Ferrochrome Silicon (FeCrSi) is an alloy composed primarily of silicon, chrome and iron.  If silica is added to the charge until its weight equals that of the ore, the smelting processes will yield what is known as ferrochrome silicon. Containing 38–42 percent silicon and less than 0.1 percent carbon, this alloy is used as a deoxidizer in the production of stainless steel and as an intermediate material in the production of low-carbon ferrochromium. Because of the greater energy required to reduce silica to silicon, the smelting of ferrochrome silicon consumes 7,600 kilowatt-hours per ton of product.

For a complete listing of ferrosilicon specifications, see ASTM A482.

Contact Us Today

McCreath Laboratories will send trained, experienced technicians to take a represented sample for you.  Whether in bulk or containers, our technicians have the training, tools and experience to collect a representative sample, ensuring that all subsequent laboratory testing is accurate and reliable.  With our mobile crushing units, ferrochrome silicon in lump form can be partially processed on site per the ISO and ASTM standards, increasing efficiency and reducing the amount of material taken off-site.

Work With The Laboratory Experts

McCreath Laboratories will employ both classical and advanced in-house techniques in the analysis of ferrochrome silicon.  The techniques have been verified through the use of certified reference materials and some are adopted directly from ASTM or ISO standards.  A typical ferrochrome analysis would be done as follows:
