Definitions
- Grain structure of the structure fine grain hardening positive on the strength and at the same time on the toughness properties. With a small grain size, the strength and toughness properties of the steel material are improved.
- Another aspect concerns the flatness of the strip or sheet. The lower the temperature after cooling in the cooling section and the thicker the strip or sheet thickness, the more important the water application on the
- the solution of this problem by the invention is characterized in that the strip or sheet is subjected immediately after passing the work rolls of the last stand an additional rapid cooling, wherein the cooling of the strip or sheet at least partially within the
- the strip or sheet is preferably made by first casting a slab in a continuous casting plant, then placing it in an oven,
- a steel strip or a steel sheet is preferably produced.
- the strip may be steel strip to which alloying constituents are added.
- the rolling mill is preferably a hot rolling mill.
- the quick cooling preferably extends from the interior of the last
- Roll stand of the rolling mill in the conveying direction ie in the rolling direction
- the cooling device behind the last rolling stand of the rolling mill in the conveying direction preferably begins at a distance greater than 10 m.
- a rapid cooling is arranged in the last frame of the finishing train.
- the time between the passage of the last roll gap and the cooling of the strip or sheet is thus minimal.
- the rapid cooling is preferably designed so that cooling rates above 1 000 K / s at the surface are possible.
- the amounts of water are applied in such a way that optimum flatness results.
- the rapid cooling measuring instruments for the thickness of the band or for the same temperature
- the present invention allows the improved production of strips and sheets, in particular of metallic materials (especially steel and iron alloys) in hot and heavy plate mills.
- the resulting grain structure is the result of recrystallization and recovery processes occurring in the material during forming.
- Grain growth takes place especially after the last pass in a hot strip mill or in a heavy plate stand and can be prevented or reduced by the earliest possible cooling of the strip.
- the present invention provides a response and describes a
- Cast continuous casting then heated in a roller hearth to the desired oven temperature and immediately afterwards in the finishing mill (rolling mill) rolled down to the finished strip thickness (heating insert).
- the slab can also be heated in the oven after a longer laytime and then further processed in the rolling mill (cold use).
- the necessary furnace temperature depends essentially on the final thickness and bandwidth to be rolled as well as on the
- Toughness results according to the Cottrell-Petch equation with the decrease in grain size. This can be in the form of a decrease in the DBTT transition temperature (Ductil Brittie Transition Temperature) or higher values in the
- Amounts of water are adjusted so that arise on the band / Blechober- and - underside the same temperatures, optimum flatness is achieved, and the band / sheet edge is like the center of the tape flat on the roller table. However, it is necessary to increase the amount of water on the bottom.
- the single figure shows schematically the last framework of a finishing train for producing a steel strip and a subsequent laminar cooling including coiler.
- the figure shows the rolling stand 2 of a finishing train.
- the strip 1 is rolled in the finishing train and leaves in the conveying direction F the last rolling stand 2.
- Rolling stand 2 the belt 1 is cooled, using a quick-cooling 4 is used, which corresponds in structure to the classical construction.
- a cooling medium (water) is sprayed onto the top and bottom of the belt 1.
- the cooling device 3 is divided into 10 sections.
- Embodiment amounts to about 9 m from the middle of the roll stand 2 amounts;
- Embodiment at about 14 m behind the center of the rolling mill. 2
- Behind the cooling device 3 is a reel device 5 for
- Temperature measuring elements 6 and 7 determine the respective temperature at the corresponding location in order to be able to monitor the course of the process.
- the proposed method is used in combination with a CSP plant with X-strands, oscillation and use of the tunnel kiln, or in a conventional hot rolling mill.
