Definitions

  • the invention relates to a method and a plant for the production of hot-rolled steel strip from a continuously cast semi-finished product in directly successive steps
  • Hot strip is produced, for example, in such a way that a cast semifinished product, the weight of which is determined by the subsequent coil weight of the finished product, is shaped to the desired geometric dimensions by one or more rolling processes. These processes usually run in succession and not simultaneously. However, the sequential process sequence requires long processing times, complex rolling devices and significant ones
  • the selection of suitable casting parameters is particularly important due to the strict restriction in hot strip production to finish rolling the products in the austenitic range ( ⁇ 880 ° C).
  • Casting speed plays a major role, because in continuous operation it determines the temperature control throughout the system.
  • the object of the present invention is to provide a method and a plant for the production of hot strip from continuously cast semifinished product, in which or in which the hot strip is rolled directly from the melt into a finished product in a continuously endless process, the finish rolling in austenitic temperature range takes place.
  • the process heat of the casting process is to be used in the production of the hot strip, so that the process and the plant work more economically than conventional discontinuous processes and plants.
  • a plant for carrying out the process for the production of hot-rolled steel strip from a continuously cast semifinished product in directly successive work steps is characterized in that the rolling mill consists of the number of roll stands corresponding to the deformation steps, the working roll diameter of all the roll stand being less than or equal to 600 mm. With such work roll diameters, the necessary deformation of the
  • the working roller diameter is ⁇ 450 mm at least in the last two roll stands. Since the proposed plant and Process concept is particularly well suited for the production of the thinnest hot strip, work rolls with a small diameter have an advantage due to more favorable deformation conditions in the roll gap.
  • a further feature of the invention provides that a compensating section is provided between the casting machine and the rolling mill to improve the temperature homogeneity in the slab.
  • a compensating section can consist of a known type of compensating furnace in which heat is optionally supplied to the slab.
  • the compensating section can consist of a covered roller table of known design or also of a covered roller table in connection with an induction furnace. This can be both upstream and downstream of the rolling gear.
  • heating and / or cooling units are provided between two or more roll stands for setting any temperature profiles of the strip during processing.
  • any temperature curve in the system can be set, with which the requirements of various processes for ferritic rolling can also be met.
  • the casting system is equipped with an automatic control of the strand cooling, which positions the sump tip at any time as close as possible to the end of the continuous casting machine. This maximizes the energy content of the slab entering the rolling mill.
  • Devices for positive and negative roll bending are preferably provided in the roll stands of the rolling mill. With such devices, the Waizprofil of the belt can be influenced during the machining process according to the circumstances and goals.
  • the gripping condition a ⁇ is violated in at least one roll stand. Because the proposed System and process concept enables a virtually endless casting and rolling process, the otherwise indispensable feed condition ⁇ ⁇ does not have to be met for rolling. Only the drawing condition ⁇ ⁇ 2 ⁇ , the fulfillment of which guarantees the maintenance of the rolling process, must be fulfilled for this process. The possibility of violating the drawing-in conditions results in considerable technical and economic advantages, since work rolls with a smaller diameter can be used, which reduces the rolling force and the rolling moment. This leads to smaller and lighter rolling stands as well as smaller main drives.
  • At least the main drive of a scaffold is controlled via a minimum tension control. This is used advantageously in applications such as the proposed method, in which large rolling moments and large rolling stock thicknesses occur. This eliminates the need to install a looper between the scaffolding.
  • a vertical diving stand is provided in front of the first rolling stand, with which the edges of the cast semifinished product can be compressed. With a vertical stitch in front of the first horizontal frame, both the edge geometry and the
  • the only drawing figure shows a system according to the invention for the production of hot-rolled steel strip with a finished strip thickness of 1.0 mm.
  • 1 with a known ladle turret is designated, with which the mold 3 of a thin slab casting system is fed via the distributor channel 2.
  • the guide frame of this thin slab casting system is designated 4, to which the curved part 5 of the Thin slab caster with a rebending unit 6 connects.
  • the compensating furnace is designated, in which the temperature of the continuously cast semifinished product is homogenized over the cross section.
  • 8 denotes the scale washer following the equalizing furnace for the semi-finished product, to which the hot rolling mill with seven four-high stands 9 to 11 and 14 to 17 is directly connected.
  • the rolling mill is followed by a run-out roller table with cooling 18, a cross-cut shear 19 and the two hot bath reels 20. Between the stands 11 and 14 there is a temperature control element 12 for optional heating or cooling (active and passive) of the strip and a further device for descaling 13.
  • the semi-finished product leaves the continuous casting mold 3 at a speed of 0.09 m / s and a thickness h 0 of 100 mm.
  • the temperature of the semi-finished product is 1240 ° C.
  • the semi-finished product passes through the equalization furnace 7 and the scale washer 8, the temperature behind the scale washer being 1188 ° C. This is the temperature at which the semi-finished product is introduced into the first four-high mill stand 9, in which the thickness of the semi-finished product is 58 mm is reduced, which simultaneously increases its speed to 0.16 m / s, the temperature of the semi-finished product falling to 1131 ° C.
  • the thickness of the rolling stock was reduced to 29 mm
  • Requirements of the rolling process can optionally be increased or decreased.
  • the strip Before entering the next roll stand 14, the strip is descaled in 13. It enters the scaffolding 14 with 1018 ⁇ C.
  • the rolled stock In the rolling stand 15, the rolled stock is pierced with a thickness of 4.8 mm, the piercing speed is 1.97 m / s at a temperature of 983 ° C.
  • the thickness of the rolling stock is reduced to 2.1 mm by a further reduction in the roll stand 15, and the speed increases to 4.51 m / s.
  • the rolling stock enters the scaffold 16 at a temperature of 949 ⁇ C, in which the thickness is reduced to 1.2 mm and the speed is increased to 7.88 m / s.
  • the rolling stock is pierced at a temperature of 902 ° C. and rolled out to a final density of 1.0 mm.
  • the exit speed is 9.46 m / s at Temperature of 880 ° C.
  • the condition for the austenitic rolling of the steel considered here, a St 37, is thus fulfilled.
  • the rolling stock is alternately wound onto one of the two hot strip reels 20 and, after the desired coil weight has been reached, cut off by the cross-cutting shears 19.
  • the inventive measures consist in producing the strip directly from the melt in a continuous, endless process, that is to say not allowing the intermediate product slab to be separated. Only the finished hot strip is cut according to the coil weight. As a result, the casting heat in the entire system is fully utilized for the subsequent forming operations. With appropriate coordination of the system, e.g. the size of the work rolls, intermediate heating of the slab or belt is not absolutely necessary.
  • the final rolling temperature can also be influenced via a temperature control system (heating and / or cooling) in the process line.
