Abstract: These days, ensuring the high quality of thin products (0.6-2.0 mm) is the most promising direction for the development of hot-rolled strip production. Hot-rolled strips can be used in place of a more expensive cold-rolled strip. In the production of ultra-thin cold-rolled strips, the use of thin hot-rolled strips as a rolling stock allows to significantly reduce the cost of the latter (at least 20%). However, the replacement of cold-rolled strips with hot-rolled ones is possible only in the case when hot-rolled steel will completely satisfy a number of technological requirements, i.e. have a satisfactory microstructure and the required level of mechanical properties, etc. An effective tool for influencing the formation of the structure and properties of steel is targeted hot rolling sheets on a suitable mill in combination with controlled cooling. Therefore, the use of reserves to improve the quality of sheets by improving the design of the mill and the temperature-deformation modes of rolling becomes one of the most important tasks facing producers of rolled metal. It is known that hot deformation of austenite with controlled temperature-deformation mode and subsequent cooling of rolled products is one of the most effective ways to improve the properties of rolled products.
