ON THE DEPENDENCE OF THE QUALITY INDICATORS OF METAL PRODUCTS ON THE STRUCTURE AND PROPERTIES OF MELTS

The article is devoted to a detailed study of the dependences of qualitative indicators of metal products on the structural state and properties of melts. The effectiveness of modern technologies for smelting steels and alloys is based on a deep understanding of the physics-chemical processes occurring in liquid metal. The main attention is paid to the results and prospects of the introduction and application of time temperature treatment (TTT) of the melt, which makes it possible to purposefully regulate its condition and improve the quality of the solid metal. An array of experimental data is provided confirming the positive impact of the technology under discussion. Specific examples of the use of TTT melt in industrial enterprises in the manufacture of a wide range of metal products: structural, tool and stainless steels, as well as cast iron for various purposes are considered.
