The elemental analyzer is an instrument used to determine the composition, structure, and certain physical properties of a substance. It has been widely used in metallurgy, minerals, machinery, casting, chemical and other industrial and mining enterprises as well as research institutes and technical quality supervision departments. Generally can be divided into organic element analyzer, computer multi-element analyzer, metal multi-element analyzer.
When the elemental analyzer is used, different substances have various qualitative and quantitative differences in various physical and chemical properties, such as color, odor, thermal conductivity, wavelength of light energy absorbed, and difference in magnetic properties, thereby judging the composition of the substance. Metal element analysis instrument is to use these characteristics to complete the qualitative analysis and structural analysis. Qualitative analysis using elemental analyzers must first fully understand the various physical and chemical properties of the substance to be analyzed and other substances coexisting with it, in order to select or manufacture the qualitative difference or significant difference between the substance to be analyzed and other substances. Analytical instrument basis. The sampling method of the five elements analyzer during use is also a key step to analyze the accuracy of the test results.
Sampling methods should generally follow the following principles:
(1) Samples used for the analysis of finished chemical compositions of steel must be taken in representative locations of molten steel or steel. The sample should be uniform and can fully represent the chemical composition of each tank steel and should have sufficient quantity.
(2) Specimens for chemical analysis can be drilled, shaved, or made with certain tools. Cutting should be crushed and mixed evenly. Do not use water, oil, or other lubricants when cutting, and remove surface oxide scale and dirt.
(3) For large-section steels, the swarf shall be drilled parallel to the axis from the center of the cross-section of the steel to the middle of the edge, or drilled from the side of the steel material perpendicular to the centerline of the shaft. At this time, the drilling depth shall reach the axis of the steel or billet. Heart.
(4) For steels with small sections, the chips shall be taken from the entire cross-section of the steel or drilled in the rolling direction from the cross-section.
(5) When there is dust or oxide on the surface, it should be cleaned accordingly.
The organic element analyzer adopts advanced Dumas' principle of high temperature decomposition. The perfect combination of static combustion and dynamic combustion makes the instrument have high precision and sensitivity. It has a wide user base in scientific research, environmental protection, chemical industry, coal and other industries. Enjoy a high reputation.
The metal multi-element analyzer can satisfy C, S, Mn, P, Si, Cr, Ni in carbon steel, alloy steel, stainless steel, gray iron, ductile iron, heat-resistant steel, Masteel, wear-resistant steel and cast iron. Mo, Cu, Ti, V, Al, W, N metal multi-element analyzers have established a powerful database for analyzing the storage and query of result data and working curves, and the data modification and the addition and deletion of curves are convenient.
