Ferroalloy analysis

Ferrous alloys are widely used in ferrous metallurgy for steel deoxidation, desulfurization, and doping in order to improve its properties such as strength, hardness, wear-resistance, corrosion and oxidation resistance. In nonferrous metallurgy they are used as furnace feed while smelting copper and aluminum alloys for welding electrode covering. Ferroalloy composition control is required while manufacturing, as well as consumer entrance control.

The exact knowledge of ferroalloy composition provides achievement of required parameters of products with minimal raw material spending.

Modern analysis methods should provide rapid and economically efficient determination of compounds with high reproducibility and accuracy. Standard optic-emission methods of analysis with spark or arc excitation are almost not applied because of ferroalloy complex structure. Traditional chemical methods cannot provide sufficient rapidness (one element analysis can occupy several days), are rather expensive and labour costing.

X-ray fluorescence method provides determination of element concentrations in ferroalloys rapidly with high accuracy. Sample preparation is simple and requires grinding the sample material to the particle size of 50 microns and pressing into a pellet. Sample preparation with borate flux fusing is admissible.

X-ray fluorescence method is successfully used for ferroalloys composition control.
