Furthermore, the invention relates to a plant for producing a microalloyed steel.
  • Thermomechanical rolling is an established process. Microalloyed steels have become increasingly important in recent times. Tubular steels (according to API Specification 5L) are one of the most important subgroups within the microalloyed steels. The demand for these steels is steadily increasing. The majority of tubular steels are produced on plate rolling mills. However, tube steels can be produced, in particular with not too great final thicknesses and final widths, as well as on hot strip mills, so-called CSP plants and other hot rolling facilities. Particular attention is paid to the production of microalloyed steels in general and of tube steels in particular to the temperature profile as a function of time (or as a function of the location within the manufacturing plant). This process, in combination with the decrease distribution, significantly influences the development of the microstructure and thus determines the mechanical and technological properties of the steel. For this reason, for example, one uses powerful cooling devices behind the finishing train, by means of which the desired temperature profile can be set.
