Effect of Controlled Rolling on the Structural and Phase Transformations

Abstract

The development of ferrous metallurgy is mainly due to the requirements of the leading metal-consuming industries to improve the performance properties of structural steels to increase the permissible loads, to reduce metal consumption and to improve the reliability of machines, structures, main gas pipelines, etc. With significant volumes of rolled metal production, reducing energy consumption and consuming raw materials during its production also come to the fore. In this regard, important and relevant works are the works aimed at creating the fundamentals of metals science and the development of new technologies that allow manufacturing the products with the required combination of properties directly in the rolling mill stream (excluding subsequent heat treatment) by purposefully controlling the processes of structure formation, as well as expanding the areas of the practical application of such technological schemes (in terms of brand and size assortment, rental destination, etc.). Such an approach makes it possible to increase the competitiveness of metal products determined by the achieved combination of metal characteristics, while reducing the cost of its production.
