Among the metals are widely used in various industries , steel and non-ferrous materials and their alloys have a special place, thanks to a good combination of high technology and operating performance. The continuously increasing demand for these materials imposes more stringent requirements for the product, identifies the need for the release of new complex alloys with special properties with narrow tolerance limits on the content of components and impurities. In the processes of production of flat and bar products metals are external effects and each operation of the process is characterized by a particular state, corresponding to a prerequisite for further processing to the final size. In the case of the exercise of any discrepancies, anomalies of structure-sensitive properties. The first and very responsible operation is the hot rolling of metal, sometimes accompanied by peals of destruction known as the thermal fragility up to the melting or destruction of the bands in the cold rolling when it would exhaust modes of deformation. On technological plasticity pressure treatment with the consideration of the behavior of metals in the deformation zone and the factors that influence the rolling process, paid much attention. In this context, new steel grades designed not only to reduce the weight of the car, but also to improve safety in the event of a collision. These were combined with increased moldability high strength over a wide temperature range and strain rate. The progressive high-strength steels, including duplex steels especially (DP) and transformation-induced plasticity steel (TRIP), characterized promising results in this area, while their unique mechanical properties can be ensured by the user specifications, and by alloying and processes parameters . Intensification of rolling (increased velocity and the resulting increase in unit quantities deformation, etc.) leads to uniquely enhance the role of the phenomena taking place on the surface of the metal contact with the tool. Conditions on the contact surface, particularly during cold rolling and strips and bands as well as exceptionally high demands for surface condition of finished products as the purity and the characteristics of microgeometry, require that the application process lubricants . A special place is occupied with studies to determine the conditions of formation of micro-geometry surface finished products at all stages of production. An important objective of research in this area is a definition of the conditions for obtaining a regulated micro-geometry and identification of parameters that can provide the required values of the characteristics that determine the quality of the surface of the finished products. Another important characteristic of surface quality of the cold- rolled strips is microfibre characterized waviness profile with a wavelength of > 800 microns. This parameter has a decisive importance on the quality of paint. An important aspect of the production is to summarize the section rolling multi-vector data on the formation of quality products. These works are in the process of production of a variety of products and section rolling affects the development and creation of mathematical models of production associated with the calibration of the working tool and the formation of structure and mechanical properties. On the basis of experimental data obtained by the equation of the curve to determine the limit of hardening resistance to deformation during hot forming and mechanical properties of the finished steel rods for steel 40HGSMA , 80G14NZ . Currently, studies the influence of technological parameters of production of long rails, combined with the rolling process and heat treatment , due to the transition to the modern technology of the rails and the development of deformation modes using universal rolling stands.
