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.
  • tubular steels are produced on plate rolling mills.

Accordingly, an improved control of the course of the temperature according to a desired profile over time or over the conveying path should be possible so as to be able to better control and control the structure development. Furthermore, a more flexible production of micro-alloyed steels, in particular of tubular steels, should be possible.

  • At least one of the elements further furnace, further cooling section and temperature-insulating element can be arranged to be pivotable about an axis of rotation pointing in the conveying direction, that one of the elements can optionally be introduced into the process line.
  • the temperature can be either raised, kept constant or lowered both before the roughing mill and between the roughing train and the finishing train.
  • the proposed procedure or device allows a targeted influencing of the temperature of the slab before Vorwalzung depending on material analysis, material dimensions and material properties.
  • a targeted influencing of the temperature of the pre-strip before the finish rolling is possible depending on the material analysis, material dimensions and material properties.
  • the method can be used for different thermomechanical treatments.
  • the installation of slab cooling can be done before the pre-deformation of the slab in the roughing stand.

  • the low inlet temperature ensures that during the almost isothermal rolling in the finishing train recrystallization and grain growth largely avoided and almost the entire deformation is accumulated, so that in the subsequent transformation results in a very fine-grained structure.

  • thermomechanical treatment By cooling the slab, the extent of thermomechanical treatment can be further increased and grain growth between roughing and finish rolling lines can be restricted. In this case, a complete recrystallization must nevertheless be ensured, which is why this procedure is particularly suitable for tubular steels with low levels of micro-alloying elements and lower slab thicknesses.
  • FIGS. 4 . 5 and 6 show plant concepts, in which mainly in comparison with the solution according to the Figures 2 and 3 the strip cooling prior to the finish rolling was replaced by an induction heater or a furnace.
