Determination of main elements in ferrosilicon, ferromanganese and ferrochrome binary alloys by portable X-ray fluorescence spectrometer Compass500 element analyzer

The importance of silicon in steelmaking. Silicon-based ferroalloy (FeSi) is an alloy of silicon and iron used as an important additive in the manufacture of steel products. The silicon in FESI alloys is mainly used to deoxidize steel, but also as an alloying element to improve the final quality of steel. Silicon can increase material strength and wear resistance, elasticity (spring steel), oxidation resistance (heat resistant steel), while reducing electrical conductivity and magnetoelasticity (electrical steel).

Ferroalloys are alloys that consist of more than one or two metallic or nonmetallic elements fused with iron. For example, ferrosilicon is silicon and iron formed Fe2Si, Fe5Si3, FeSi, FeSi2 and other silicides, they are the main components of ferrosilicon, silicon in ferrosilicon mainly exists in the form of Fesi and FeSi2, especially Fesi is more stable. The melting point of different components of ferrosilicon is not the same, such as 45% of ferrosilicon melting point is 1260℃, 75% of ferrosilicon is 1340℃. Ferromanganese is manganese and iron alloy, which also contains carbon, silicon, phosphorus and other small amount of other elements, according to its carbon content is different, ferromanganese is divided into high carbon ferromanganese, medium carbon ferromanganese and low carbon ferromanganese. Ferromanganese alloys containing enough silicon are called silico-manganese alloys. Ferrochrome is an iron alloy of chromium and iron. It is an important alloy additive for steelmaking. Ferroalloy is not a metal material that can be used directly, but mainly as a deoxidizer, reducing agent and intermediate raw material of alloy additives in steel production and casting industry.

The content of main elements in ferrosilicon, ferromanganese and chrome-ferroalloy is analyzed by X-ray fluorescence spectrometry Conpass500 element analyzer. The parameter setting of the instrument is analyzed and studied, and the measurement parameters are optimized. The sample is ground by 60 purpose sandpaper before treatment to ensure that the sample has a smooth plane, and the strength will be collected by PAD The data are sorted and drawn working curve, the basic parameter method is used for quantitative analysis under the best conditions, the measurement results are compared with the wet measurement value, the measured value is consistent with the real value and the relative standard deviation is within the allowable range, to meet the daily production needs, reduce the loss in the screening of raw materials, and ensure the qualified rate of finished materials.
