Definitions

  • the invention relates to a method for rolling metal strips by means of roll stands, in which the rollers, which belong together in pairs and rotate in opposite directions, are driven at different peripheral speeds and the metal strip wraps around each of the rollers at least over part of their circumference, and in which the thickness reduction of the Metal strip is brought about by generating different shear stresses in the different material cross-sectional zones with sliding sliding of the crystals.
  • sliding glide is to be understood as a change in shape in which the crystals of the rolling stock are deformed in the sliding direction only by shear forces acting parallel to a sliding plane, without rotation of the sliding planes occurring.
  • This thrust glide results from the shear stress generated by the different peripheral speeds of the rollers driven in pairs in opposite directions, i. that is, from an elastic tension caused by external forces acting tangentially in the cross-sectional area of the rolling stock.
  • the generic rolling process is therefore - to put it succinctly - a sliding sliding or push rolling process
  • the invention also relates to a rolling mill for carrying out this method, which can also be referred to as a sliding sliding or push rolling mill in accordance with the preceding definition of the term.
  • each of the cooperating rollers is driven by its own motor.
  • the roller having a higher peripheral speed is driven at a constant speed which is independent of the applied load, while the roller having the lower peripheral speed reverses the speed reverse ratio to the applied load is selected and thereby the ratio of the peripheral speed of cooperating rollers corresponds to the ratio of the thickness of the rolling stock at its entry and exit sections.
  • the purpose of the invention is to overcome the problems that arise in the sliding sliding or push rolling method and rolling mills according to DE-OS 19 40 265 and DE-AS 21 33 058. Therefore, the invention has for its object to hew a method and a rolling mill of the generic type so that a thickness control in all sliding sliding or pushing rolling zones can be completely omitted.
  • This object is achieved according to the invention mainly by the fact that the final thickness control for the rolling stock while maintaining a predetermined circumferential speed difference ratio between the individual rolls of the sliding sliding or push rolling stand by controlling the stitch take-off on a sliding sliding or push rolling mill. t upstream and / or downstream four-high rolling mill is carried out.
  • the predetermined circumferential speed difference ratio between the individual rollers of the sliding sliding or push-rolling stand by mechanical and / or electrical coupling of the individual roller pair drives, in particular by one of the rollers of a roller pair of mutually coupling gear (19 ... 30) acted upon by a preferably common drive (18).
  • the circumferential speed difference between the individual rollers of the sliding sliding or. Thrust roller mill can be predetermined by stepping the gearbox.
  • the roll gap control of the four-high roll stands is effected by measuring the thickness of the rolling stock on the inlet and outlet sides of the sliding sliding or push roll stand.
  • the speed of the drive for the sliding-sliding or push-rolling stand can be kept constant and the stitch take-off and / or the run-out speed thereof can be regulated and / or preset with the preceding four-high rolling stand.
  • the process according to the invention has the essential advantage that the preselected reduction is achieved when the rolling mill is started up.
  • FIGs 1 to 3 of the drawing are rolling mills for reducing the thickness of metallic strip material, bapw. for rolling out sheet metal strips made of carbon steel, to each of which an outlet or brake reel 1 and an outlet or a reel 2 are assigned on the inlet side.
  • Each rolling mill itself consists of a so-called sliding sliding or push rolling stand 3 and at least one four-high rolling stand 4 or 4 ', 4 ".
  • the four-high mill stand (4) is built up in front of the inlet side of the sliding gliding or pushing rolling mill 3, while according to FIG. 2 the four-high rolling mill 4 is arranged downstream of the outlet side of the sliding gliding or pushing rolling mill 3.
  • the metallic strip material 5 is drawn off from the unwinding or braking reel 1 by means of a driving device 6 'and then introduced into the actual rolling mill by means of a further driving device 6 ".
  • the metallic strip material 5 first passes through the roll gap between the two driven work rolls 7 of the four-high mill stand 4, the work rolls 7 being set against the metallic strip material 5 via the two support rolls 8 with adjustable rolling pressure.
  • a thickness measuring device 9 and 9 ' is provided on the inlet and outlet sides of the four-high mill stand 4, which continuously shows the strength of the into the four-high stand 4 incoming and out of this four-high framework 4 emerging metallic strip material 5 determined.
  • the metallic strip material 5 is then introduced into the inlet side of the sliding-sliding or push-rolling mill 3 via a deflection roller 10. There the metallic strip material 5 runs tangentially onto the lower roller 11 'of a first cooperating pair of rollers 11, wraps around this over a large part of its circumference and then occurs; in the nip of the pair of rollers 11 tangentially on the upper roller 11 ", which in turn wraps around a large part of its circumference.
  • the metallic strip material 5 then runs from the upper roller 11 "of the first cooperating roller pair 11 initially for the purpose of strain relief in a similar manner, through the roller pair 11 through a so-called S-roller pair 11 '", from there again onto the lower roller 12' of a second, cooperating pair of rollers 12. It loops around this and the upper roller 12 "of the pair of rollers 12 in the same way as the rollers 11 'and 11" of the first pair of rollers 11 working together, before it is then again relieved of tension by an S-pair of rollers 12' " and then in a corresponding manner to a third, cooperating pair of rollers 13 formed from the lower roller 13 'and the upper roller 13 ".
  • the metallic strip material 5 arrives for the purpose of strain relief via an S-roller pair 13 ′ ′′ toward the outlet side of the sliding-sliding or push-rolling stand 3 and from there via deflection and drive rollers 14 and a deflection roller 15, the take-up reel or pull reel 2.
  • a thickness measuring device 16 is again arranged behind the outlet side of the sliding-sliding or push-rolling stand 3, which continuously determines the thickness of the finished rolled metal strip material 5 and as a control variable for the superimposed thickness control backwards on the four-high mill stand 4.
  • a separating shear 17 is installed behind the outlet side of the sliding sliding or push-rolling stand 3, with the aid of which the metallic strip material 5 can be cross-divided if necessary.

  • the percentage extent of the stitch decrease is not effected by appropriate adjustment and adjustment of the roll gap, but rather by the fact that the rollers 11 ", 12" and 13 "of the cooperating roller pairs 11, 12 and 13 each have a larger peripheral speed corresponding to the percentage stitch decrease are driven as the rollers 11 ', 12' and 13 'of the individual roller pairs 11, 12 and 13.
  • each of the roller pairs 11, 12 and 13 is assigned its own drive, the mutual adaptation of the peripheral speeds for the rollers of the successive roller pairs 11, 12, 13 can be realized most simply by electrical coupling of the successive drives, the electrical coupling circuits used in this respective circumferential speed difference ratio between the two rollers of the preceding roller pair is taken into account.
  • the electrical coupling circuits can be part of a process computer assigned to the rolling mill.
  • roller pairs 11, 12 and 13 of the same can be driven by a common motor 18, as can be seen from FIGS. 5 and 6.
