Elemental (Composition) Analyzer / Melting in Front of the Furnace

Pellets

Pellets are an important type of iron ore, formed into spherical particles by mixing concentrates and additives. The composition of the pellets is a key factor affecting their physical and chemical properties. The seven main components in pellets—TFe, Al2O3, CaO, MgO, SiO2, P, and S—have always been important criteria for determining pellet quality. In the past, chemical analysis methods were mostly used to determine the composition of pellets, which was labor-intensive and had a relatively long analysis cycle. To better meet the needs of sintering production and provide faster and more accurate analysis results, LANScientific recommends using X-ray fluorescence spectrometry (XRF) to analyze the seven main components and trace elements (Cu, Pb, Zn, As, Sn, K2O, etc.). The precision and accuracy of the analytical results are comparable to those of chemical analysis methods!

Steel slag

Steel slag mainly consists of calcium, iron, silicon, magnesium oxides, with small amounts of aluminum, manganese, phosphorus, and other oxides.

Its main minerals are tricalcium silicate, dicalcium silicate, calcium forsterite, calcium magnesium rhodonite, calcium ferroaluminate, and solid solutions composed of silicon, magnesium, iron, manganese, and phosphorus oxides, and it also contains small amounts of free calcium oxide, metallic iron, fluorapatite, etc.

XRF is commonly used in steel slag analysis. It can rapidly detect the metal components in steel slag and provide useful reference data for the steel industry. This is of great importance for steel production and environmental protection, helping to optimize production processes, improve product quality, and ensure sustainable development.

Slag

Chemical analyses show that the main components of steelmaking slag are CaO, SiO2, Fe2O3, FeO, MgO, P2O5, MnO, CaS, etc. In addition to the simple molecular compounds mentioned above, these substances can exist in various forms in the slag, and can also form complex compound compounds such as 2FeO·SiO2, 2CaO·SiO2, 4CaO·P2O5, etc.

The properties of slag play a very important role in ensuring the smooth progress of the smelting process and guaranteeing the quality of metal products. Therefore, slag composition analysis is indispensable in steelmaking and other smelting processes. X-ray fluorescence spectrometry (XRF) is a commonly used tool in slag detection. It can be used to quickly and accurately analyze the element content and composition of slag to help improve the steelmaking process and ensure product quality.

Ferrosilikon

Ferrosilicon, produced using coke, steel scrap and quartz (or silica) as raw materials, is an iron-silicon alloy melted in molten iron using an electric furnace to melt silicon at high temperatures. It is an important type of alloy in the smelting industry. Ferrosilicon has excellent physical and chemical properties and is widely used in the steel industry, foundries, and other industrial productions.

Ferrosilicon is divided into four categories according to the smelting method: high-silicon ferrosilicon (GG), ordinary ferrosilicon (PG), low-aluminum ferrosilicon (DL), and high-purity ferrosilicon (GC). X-ray fluorescence spectrometry (XRF) is commonly used in the analysis of ferrosilicon alloys to determine the composition of silicon, phosphorus, manganese, aluminum, calcium, chromium, and other elements in real ferrosilicon alloy samples.

Silika

Silica is the general name for vein quartz, quartzite, and quartz sandstone, with the chemical formula SiO₂. Its main applications can be roughly listed as follows: refractory materials in the metallurgy industry, quartz glass, and components in cement.

As a raw material for industrial silicon smelting, the purity of silica is directly related to product quality. Therefore, there are strict requirements regarding the content of impurities in silica for industrial silicon smelting. The main impurities in silica generally include Fe₂O₃, Al₂O₃, CaO, MgO, K₂O, Na₂O, MnO, TiO₂, etc. Silica has different applications depending on the silicon content and impurity levels.

The XRF method can be used to analyze the impurity elements in silica samples for industrial silicon production. When combined with the glass melt sample preparation method and X-ray fluorescence technology, it can provide customers with highly accurate and satisfactory analysis results!
