In this article, the technology of liquefaction of high-grade steels and increase of resource efficiency is developed. Non-metallic inclusions are foreign particles trapped in steel during the manufacturing process. The inclusions have different chemical compositions and affect the mechanical properties of steel in different ways: ductility, hardness, mach inability and corrosion resistance. As a rule, the less non-metallic inclusions are contained in the steel, the higher its quality. Therefore, the analysis and documentation of non-metallic inclusions is an important step in quality control.
