Ferroalloy means various alloys of iron with a high proportion of one or more other elements such as manganese (Mn), aluminium (Al), or silicon (Si). Ferro alloy are widely used in the production of steels and alloys The alloys add distinctive qualities to steel and cast iron or serve important functions during production and are closely associated with the iron and steel manufacturing industry, with the leading consumer of ferroalloys. The leading countries of ferroalloys producers erroalloys are China, South Africa, India, Russia and Kazakhstan, which accounted for over 80% of the world production.
The common types of ferroalloy deoxidizers are ferrosilicon alloy, manganese-silicon alloy, and ferromanganese alloy. These three alloys are the top three alloys in the market in terms of output and consumption. In addition to deoxidation, they can also be used as alloy additives. By increasing certain metals, they can improve steel toughness, plasticity, corrosion resistance and other properties.
As ferroalloy is an important additive in the iron and steel smelting process, and its composition directly affects the quality of iron and steel products, so it is important for
fast and accurate analysis of ferroalloy chemical composition is very important.
Presently, “wet chemistry” is the most common method used to carry out precise analysis of ferroalloys. Yet, it has high labor costs and requires long sample preparation time.
For the analysis of FeSi alloys, X-ray fluorescence (XRF) spectrometry is an ideal alternative technique, providing high throughput and simple routine sample preparation.
The X-ray fluorescence analysis method has the advantages of fast analysis speed, wide detection range, stable and reliable results, etc. for the analysis of ferroalloys.
For a fast sorting, samples can be prepared as powders in cups. Pressed pellets are chosen as sample preparation when higher accuracy is required but special calibrations are necessary, especially if the grain size of the sample differs from available reference samples.
To avoid the influence of different grain sizes, the samples can also be prepared as fused beads. When preparing fused beads, the sample material must be oxidized to avoid damage of the platinum crucible. Standard operation procedures describe the process and list the required chemicals. With that approach even different types of ferro alloys can be analyzed with one method.
