  • ABSTRACT [30] Foreign Application Priority Data A method of, and apparatus for, conveying a strand May 29,1972 Germany .[2226095 through a Strand guide mechanism Of a Continuous casting installation by means of electro-motor force, 5 5 C
  • the apparatus of the invention contemplates arrang- [56] References Cited ing windings serving as theprimary of a linear motor UNITED STATES PATENTS parallel to the strand guide mechanism, the secondary of the linear motor being constituted by the strand gli z s Q which is located in the strand guiding mechanism.
  • the present invention relates to a new and improved method of, and apparatus for. conveying a strand through a strand guide mechanism or roller apron of a continuous casting installation by means of electromotor force.
  • strand is used in its broadest sense to encompass not only a cast strand but also a dummy bar.
  • the dummy bars and the cast strands are guided by rollers.
  • a number of the rollers are driven in an electro-motor fashion, wherein the drive force is transmitted by friction from the surface of the rollers to the surface of the strand. Due to the frictional drive the thin shell or skin of the strand is subjected to additional loads, intensifying the possibility of forming fissures or cracks at the strand shell.
  • the dummy bar must be considerably longer than the first guide section since the next following strand guide mechanism there must be in engagement a number of driven rollers.
  • a further object of the present invention relates to a new and improved method of, and apparatus for, conveying a strand through the strand guide mechanism of a continuous casting installation by electro-motor force.
  • Yet a further object of the invention aims at the provision of a novel methodof, and apparatus for, conveying strands through the strand guide mechanism while subjecting the strand shell or skin to lesser load.
  • Another object of the invention relates to a novel method of, and apparatus for, conveying strands through a continuous casting installation in a manner permitting the use of shorter dummy bars.
  • strand as employed herein encompasses a castor hot strand as well as the dummy bar.
  • the apparatus for the performance of the method aspects of this development comprises arranging as the vprimary of a linear motor windings parallel to the strand guide mechanism, the secondary of the linear motor being constituted by the strand located in the strand guide mechanism.
  • the windings are preferably associated with the side surfaces of the strand, and such windings can be adjusted in accordance with the momentary strand width.
  • the first motor windings can be directly arranged following the mold.
  • the motor windings are preferably encapsulated and provided with a cooling mechanism so that they do not become damaged by heat.
  • Movement of the strand is governed by electro-motor forces, the magnitude and direction of which can be regulated.
  • electro-motor forces the magnitude and direction of which can be regulated.
  • the motor windings are arranged at the dummy bar and rails which extend parallel to the strand guide mechanism constitute the secondary of the linear motor. Also in this case there can be used a very short dummy bar. Fewer windings are necessary and such are not subjected to the heat of the cast strand.
  • FIG. 1 schematically illustrates a continuous casting installation incorporating linear motor windings arranged between the guide rolls of the strand guide mechanism
  • FIG. 2 illustrates a guide segment of the strand guide mechanism viewed in the direction of the strand
  • FIG. 3 schematically illustrates a dummy bar equipped with linear motor windings

  • FIG. I there is depicted a continuous casting installation or plant having a continuous casting mold l for the production for instance of slabs.
  • a plate guide mechanism 2 After the mold 1 there is arranged a plate guide mechanism 2 and thereafter there is arranged an arcuateshaped roller apron 3 which runs-out in essentially horizontal direction, as shown.
  • an arcuateshaped roller apron 3 At the region of the narrow sides of the strand there are arranged linear motor windings 4.
  • linear motor windings 4 In order to be able to fixedly hold a dummy bar head or stoppingand withdrawing head 5 in the mold I at the start of casting two oppositely situated ther details of the strand guide mechanism.
  • brackets 9 and 10 In which there are anchored the columns 11 and 12 respectively.
  • a .lower segment member 13 At the columns 11 and 12 there is secured a .lower segment member 13 at which there .are mounted guide rollers 14.

  • linear motor windings 4 of the linear motor means L Associated with side surfaces of a strand 21 which is guided at the strand guide mechanism are the linear motor windings 4 of the linear motor means L and these windings can be adjusted by pressurized cylinders 22, 23 at the required spacing determined by stops with respect to the strand 21.
  • FIGS. 3 and 4 there is illustrated a different embodiment of the invention in which a dummy bar 3] possesses a narrower construction than the associated dummy bar head 32 for closing a mold 33.
  • a dummy bar 3 possesses a narrower construction than the associated dummy bar head 32 for closing a mold 33.
  • two oppositely situated holding members 50 In order to be able to fixedly hold the dummy bar head 32 in the mold 33 at the start of casting there are provided two oppositely situated holding members 50, only one of which has been conveniently shown at the right-hand side of FIG. 3, and which can be displaced towards and away from the dummy bar 31 as indicated by the double-headed arrow 51.

  • windings include a first motor winding arranged directly after the continuous casting mold.
  • an apparatus for conveying a strand through the strand guide means of the continuous casting installation by electro-motor force comprising windings provided at a dummy bar. and constituting the primary side of linear motor means and rail means extending substantially parallel to the strand guide means and defining the secondary side of the linear motor means.
