Abstract

Problem statement. Structural steel products are the bulk of the production of modern metallurgy. It is advisable to increase the mechanical properties of rolled products in the framework of technologies involving the use of rolling heating, which saves energy and reduces the production cost. Purpose. The choice of a rational scheme of rolling and post-deformation cooling of rolled steel made of structural steel. Material and Methods. The study material is 20 mm thick sheet steel made of S355J2 steel (EN 10025) micro-alloyed with V−Nb−Al complex. Methodology − tests for mechanical properties according to the requirements of EN 10025. Results. The mechanical properties of sheet metal are compared after performing standard hot rolling, normalizing rolling, controlled rolling, and also after controlled rolling with subsequent accelerated cooling in various modes. Conclusions. It is shown that by using controlled rolling with accelerated cooling to 460…530 °C, it is possible to significantly (by one third, up to category 500Q) increase the strength of steel with an increase in its cold resistance and at the same time maintaining plasticity at an acceptable level. Such an increase in the complex of properties is achieved without the use of heat treatment with special heating, which is an economically advantageous direction.
