Definitions

  • the invention relates to a device for removing a beard a cut edge of a continuously cast semi-finished product according to the preamble of claim 1 and a method for removing a beard with the inventive Contraption.
  • a metal melt is continuously produced in a continuous casting mold solidified and continuously at least at his Solidified metal strand is conveyed out of the mold. At one end of the discharged strand is continuously a section after a is sufficiently solidified in the interior, separated.
  • the severed Strand sections form intermediate products, so-called semi-finished products, which is intended for further processing and - depending on the others Processing steps - must meet certain quality requirements.
  • beards When cutting off strand sections by means of cutting burning arise individual cut edges of the cut surfaces generated so-called beards the thermal and / or thermochemical caused by cutting Processes. These beards depend on a number of parameters - For example, the material of the strand, the temperature of the strand and the specific processes involved in the cutting process underlying - different material properties, for example different chemical compositions or different physical Characteristics. Deviating from the properties of the material inside of the strand, the beards can be composed of one material, that has a high oxide content or is highly brittle and / or porous is. The beards disturb because of their material properties and their size and Shape when handling the semi-finished product for transport purposes or when Further processing of the semi-finished product, for example when rolling. That is why wanted to avoid the formation of beards as much as possible and Beards immediately after cutting the still hot strand material to remove.

  • This deburring device has a number of disadvantages.
  • a high rotational speed of the rotating body is required.
  • the hammers usually do not only meet the beard to be removed, but rather also to the cutting edge to be exposed or the side surfaces of the strand section.

If the beard is under pressure at one point, which is the mechanical load limit of the beard or connection of the beard to the cut edge, the beard material breaks at least piece by piece. Because the position of the axis of rotation can be changed and the Contact pressure can be specified, the stress on the device and the exposing strand section kept within tolerable, defined limits if the beard and / or the cut edge coincides with the surface of the Rotating body is brought into contact.
  • the deburring process is therefore particularly gentle. Because of the control the contact pressure can be with the device according to the invention in one Production plant a variety of strand sections with the same precision be deburred, even if the outer shape of the strand sections tolerances subject and the different beards to be removed a different Shape and / or size or different mechanical properties exhibit.

Particularly good results can be achieved if the strand section to be exposed and the rotating body before pressing of the rotating body relative to each other against the direction of rotation Surface, based on the contact point of the beard on the surface of the Body of revolution. This will avoid parts of the removed beard between the rotating body and a side surface of the Strand section and pressed against the surface of the strand. Peelings Beard material is thus always away from the surface of the strand section emotional.

  • the pivoting movement of the rotating body 21 in the direction of the web 10 of the cutting edge 3 to be revealed is restricted by a stop element 33.
  • the fluid mechanical drive 35 is designed as a linear drive which displaces the coupling part 39 and thus the axis of rotation 22 of the rotating body 21 relative to a foundation 37 of the drive 35 in the direction of arrow 38.

Since various strand sections are generally subject to certain tolerances in terms of their shape, the exact position of a cutting edge with respect to a transport path, for example the transport plane of a roller table, can only be predicted within certain tolerances.
  • the rotating body 21 In order to ensure that the strand section 1 strikes the rotating body 21, it is expedient to position the rotating body 21 before the deburring process begins so that the cut edge 3 on the foot side does not tangentially meet the surface 26 of the rotating body 21 within the tolerances to be expected.
  • the tangent 11 parallel to the path 10 of the cutting edge 3 on the rotary body 21 therefore has a distance ⁇ h> 0. 20 mm to 40 mm can be regarded as realistic values for ⁇ h.
  • An easy reproducibility of the deburring position is made possible by the stop element 33 against which the holding device 30 is pressed when the pressure P 1 in the bellows 36 exceeds a certain minimum value.

  • the size of the contact pressure with which the rotating body 21 is pressed against the cutting edge 3 or the beard 4 depends essentially on P 1 and to what extent P 1 changes with ⁇ h.
  • valves 45 and 48 By suitable control and / or regulation of the valves 45 and 48, it is possible to keep P 1 and thus also the contact pressure within the desired limits.
  • the fluid mechanical drive 35 is designed as a pneumatic drive
  • the high compressibility of gaseous pressure medium means that P 1 changes significantly less as a function of ⁇ h when the valves 45 and 48 are closed than, for example, with a hydraulic pressure medium.
