Definitions

  • the invention relates to a drive device for a continuous casting device with a pair of liquid-cooled casting rolls, between which metal melt is introduced by means of a nozzle and the cooling liquid connection and drive are arranged on different sides of the roll supporting frame.
  • Continuous casting devices of the type mentioned at the outset are equipped, via cardan shafts, with a synchronous drive which has either a distribution gear or two single gears synchronized by angular gears.
  • a synchronous drive which has either a distribution gear or two single gears synchronized by angular gears.
  • toothed spindles are often used as cardan shafts, which are relatively expensive. Since the synchronous drive, which also requires a considerable amount of space, can only be dismantled with a considerable amount of work and time, the known continuous casting devices with casting rolls are designed in such a way that a casting roll change can only be carried out from the side of the coolant connection.
  • US-A-3 552 172 describes a straightening roller drive for sheet metal straightening machines, in which each straightening roller has an individual drive in the form of an electric motor with a reduction gear, in particular in the form of a planetary gear.
  • the individual drives and the reduction gears - like the associated straightening rollers - are supported on a tiltable bearing housing, the reduction gear being received in its bearing bore.
  • This is also formed in two parts in that it is on the one hand non-releasably attached to the straightening roller in question via a sleeve-shaped wheel 13 and on the other hand is attached to the bearing housing via part of its internal toothing and the associated cover.
  • the invention has for its object to improve the manageability of continuous casting devices with casting rolls of the type mentioned at a reasonable technical effort.
  • the work and time required to change the casting roll should be reduced and the economy of the continuous casting device should be increased by improved adaptability to different operating conditions.
  • a drive device for a continuous casting device which has the characterizing features of claim 1.
  • the basic idea of the invention is then to equip each casting roll with a direct roll drive in the form of a gear motor assigned only to the casting roll in question, which is detachably attached to the respective roll neck as a freely projecting drive unit.
  • the use of such compact and mutually independent geared motors not only has the advantage that any differences in diameter of the casting rolls can be compensated for via the drive unit and the torque distribution between the casting rolls, in particular also for influencing the strand surface, can be set freely.
  • Any casting roll change that may be required can be carried out as quickly as possible by loosening the complete drive units — which also have a relatively small longitudinal extent — without the liquid cooling having to be laboriously dismantled as before.
  • the housing of the geared motor in particular the geared motor below, is held in a rotationally fixed manner on the roller support frame and is connected in an articulated manner to the housing of the other geared motor via a torque support.
  • the torque arm can preferably be realized in that the housings of both geared motors are equipped with a support arm and are movably connected to one another via a respective articulated link.
  • each geared motor has a flanged planetary gear, the output shaft of which forms a torque connection that can be produced by an axial displacement with the roll neck of the associated casting roll (claim 2); the geared motors can thus be detached from the casting rolls by a simple pull-off movement when the casting rolls are changed and placed at a suitable point.
  • a particularly simple and quickly producible axial connection between the output shafts of the geared motors and the roller journals consists in each case of a clamping ring which overlaps the respective connecting sections (claim 3) and consists in particular of two ring halves which are held together in an articulated manner and which have a clamping screw penetrating them as a closing element (claim 5).
  • the axial connection can be eliminated by loosening a single clamping screw and by unfolding the clamping ring.
  • the adjacent connection sections The roll neck on the one hand and the associated geared motor on the other hand preferably form a trapezoidal profile in cross section, which rests in the adapted recess of the clamping ring (claim 4).
  • the subject of the invention can also be designed such that the clamping ring consists of several partial rings which are clamped together in the axial direction to produce the axial connection between the geared motors and the roll neck; the adjoining connection sections can also form a different profile, for example a rectangular profile, in cross section.
  • the axial connection between the geared motors and the roller journal is further developed in that the output shaft of the geared motor is supported on a peripheral surface of the roller journal (claim 6); the output shaft thus overlaps part of the roll neck.
  • the continuous casting apparatus with casting rolls has a roll support frame with stands 1 and 2, in which two liquid-cooled casting rolls 3 and 4, one above the other, can be adjusted and removed.
  • Each casting roller is equipped (in Fig. 1 on the left side of the roller trestle) with a coolant connection 5, through which a suitable line system 6 coolant is introduced into the relevant casting roll or discharged to the outside for re-cooling.
  • roller journals 3 "and 4" are each detachably connected with their own direct drive in the form of a gear motor 8 - each consisting of a hydraulic motor 9 with a flanged planetary gear 10.
  • the roller support frame In the working position shown in FIG. 2, the roller support frame assumes a position inclined by 30 ° with respect to the vertical, in which it is supported on the stop surface 11 'of a bracket 11 1.
  • the pivoting into or out of the working position is effected after loosening a locking bolt 12 by means of a pivot drive 13 with at least one hydraulic cylinder.
  • the housings of the superimposed geared motors 8 are in the vicinity of the roller trestle, i.e. in the vicinity of the stand 2, each equipped with a support arm 14 and 15 and articulated to each other by means of a handlebar 16.
  • the lower support arm 14 is rotatably held by a bolt 17 fastened to the stand 2.
  • the support arms 14 and 15 and the link 16 connected to them form a torque support which allows the casting roll position to be changed without further structural intervention.
  • the parts 4 ′′ and 10 ′ to be connected to one another are the connection sections 4 ′′ and 10 respectively "equipped, which form a trapezoidal profile with the outer flanks 4a and 10a in cross section in the connection position indicated in FIG. 3; the associated contact surfaces, by means of which the parts 4 ′′ and 10 ′ are supported against one another in the axial direction, are designated 4b and 10b, respectively.
  • the trapezoidal profile engages via its inclined outer flanks 4a and 10a in the adapted recess 18 of a clamping ring 19, which holds the contact surfaces 4b and 10b against one another via a clamping screw 20.
  • the torque connection between the roll neck 4 "and the output shaft 10 ' consists of an intermeshing spline 4" or 10 "in the area of the respective connecting section 4" or 10 ".
  • the spline 4" of the roll neck 4 " also serves as a peripheral surface on which the output shaft 10 'of the associated Gear motor 8 supports.
  • the clamping ring 19 consists of two ring halves 19 'and 19 ", which are movably connected to one another on the side opposite the clamping screw 20 via a hinge pin 21 (FIG. 4).
  • the outer flanks 4a and 10a become at the correspondingly inclined Recess surfaces 18 'and 18 "brought into abutment, so that the contact surfaces 4b and 10b of the parts 4" and 10' are immovably supported against one another in the axial direction 19 ".
