Definitions

  • the invention relates to a system for producing steel strip, which consists of a steel strip casting mold, a set of rollers for pressing and welding together the strand shells that solidify on the steel strip broad sides, and guide rollers for diverting the steel strip to a horizontally arranged driving straightening device.
  • the known systems are complex and high-rise.
  • the relatively long steel belt guide causes energy and scaling losses, which can only be reduced through increased protection.
  • the object of the invention is to provide a simple, low-construction, reliable and maintenance-friendly system with which steel strips with a good structure and high surface quality can be produced.
  • more economical production is to be achieved by reducing energy and scaling losses.
  • the distance between the guide rollers and the surface of the press roller is greater than the thickness of the pressed steel strip. This limits the heat transfer from the steel strip to the press roll and prevents wear on the surface.
  • the radius of curvature of the guideway formed by the guide rollers is less than 800 mm.
  • a significant reduction in the heat of the steel strip on the press roller is achieved in that a heat shield is arranged between the press roller and the guide rollers above the top of the steel strip.
  • the heat shield is advantageously made of a cooled steel plate or a plate made of refractory material.
  • One method for operating the system according to the invention is that the retraction speed of the driving straightening device, which is regulated according to the outfeed speed of the press rolls, is corrected in the event of deviations of the steel strip from the desired position in the region of the guide rollers.
  • the system shown for the production of steel strip consists of the essential parts of steel strip casting mold 1, press rollers 2, 3, guide rollers 4, 5, 6 and driving straightening device 7.
  • the steel strip casting mold 1 which is expanded to accommodate a pouring tube 8, is provided with cooling tubes 10 in the walls 11 for cooling the cast steel 9.
  • a strand shell 13 that solidifies the liquid pouring sump 12 solidifies.
  • the strand shells 13 opposite on the wide format sides of the steel strip 14 are pressed and welded below the mold 1 by the press rollers 2, 3, thereby reducing the original casting format thickness to the press thickness d of the steel strip 14 is reduced.
  • the press roll 3 is stationary and the press roll 2 is adjustably mounted for setting the steel strip thickness d.
  • the steel strip 14 is guided directly below the pressing area 15 by the guide rollers 4, 5, 6 mounted on the foundation 16 around the bale underside of the pressing roller 3 to the drive leveling device 7.
  • Bearing 17 of the guide rollers 4, 5, 6 are adjusted in height by intermediate layers or adjusting devices 18 such that the distance of the guide rollers 4, 5, 6 from the surface of the press roller 3 is greater than the thickness d of the pressed steel strip 14 , that the steel band 14 below the press area 15 lifts off the surface of the press roll 3, thus avoiding excessive heating of the same by contact and wear.
  • a heat shield 19 is arranged between the latter and the press roller 3.
  • the heat shield 19 can be formed either from refractory material or from steel plates cooled inside or outside.
  • the described one-sided steel strip guide requires constant contact of the steel strip 14 on the guide rollers 4, 5, 6.
  • spacers 20 are therefore arranged between the guide rollers 4, 5, 6. Since the curve of the steel strip 14 is dependent on the ratio of the feed speed V 7 of the driving straightening device 7 to the press rolling speed V 2, 3, a position error of the steel strip determined by a processor 21 can trigger a signal for correcting the drive control 22 of the driving straightening device 7. This principle is illustrated in Fig. 2.
  • a cross-section shear 23 for the steel strip 14 and a temperature compensation furnace 24 for setting a homogeneous rolling temperature are arranged downstream of the system described.
  • the known rolling mills can be used for rolling out.
