Definitions

  • the invention relates to a method for renewing refractory plates used in slide closures on metallurgical vessels as fixed bottom or adjustable slide plates, which have at least one flow opening damaged by a wear field and a closing surface.
  • Object of the present invention is to simplify the plate repair and to improve its efficiency with the inclusion of the closing surface.
  • the object is achieved according to the invention essentially in that the worn plate is provided with a new flow opening on the closing surface and the worn flow opening is closed and formed as a new closing surface.
  • refractory plates for slide closures can be balanced, both on the flow openings and on the closing surfaces, the process steps being simple to carry out and, moreover, bringing about a significantly improved service life of the plates which receive practically new flow openings and closing surfaces.
  • Worn outflow openings are advantageously closed after cleaning with a prepared stopper, which is used at least on the sliding surface of the plate with the help of refractory putty, mortar or the like, with filling of the wear field.
  • the core of the newly drilled flow opening can serve as a plug for the old flow opening.
  • a cleaned, worn-out flow opening can also be filled up smoothly and evenly to the sliding surface with rapidly drying or setting, pourable, refractory material, including the wear field. This process is particularly simple and easy to carry out.
  • 1 means the stationary inlet sleeve and 2 the flow opening.
  • This is done for opening and closing and for throttling the closure, the sliding surfaces 9 and 10 of both plates 4 and 5 sealingly sliding on one another and generating, ending and modifying the pouring jet with the flow openings 3 and 6, so that after some operating time around the flow opening Edges around 11 and 12 wear fields arise, which make it necessary to replace the plates 4 and 5.
  • the replaced old panels, the closing areas of which usually still have sufficient operational reliability, are visually inspected and thoroughly cleaned, preferably with a machine-operated one Steel brush, repaired or renewed.
  • the slide plate 5 is given a newly drilled flow opening 6a in the largely undamaged closing area 13, while the old flow opening 6 is closed with the drill core thus obtained as a plug 14 using refractory mortar 15 or the like, with which the wear field 12 on the sliding surface 10 of the plate 5 is also filled or smoothed to form the new closing surface 13a.
  • indexable inserts i.e. to be repaired with sliding surfaces 10, 10a on both plan sides
  • the second sliding surface 10a is also first worn out before the above-described repair occurs.
  • a plug 14a prepared with a tight fit can also be introduced into the old flow opening 6 and then the wear field 12a leveled with refractory mortar 15 to the level of the sliding surface 10a.
  • the repair measures naturally also apply in the same way to the base plate 4 interacting with the slide plate 5.
  • FIGS. 5 to 7 illustrates the repair of refractory plates 20 by means of a pourable refractory material 26. It is a rotating plate 20 to be renewed, which is used in rotary closures and whose flow openings 21 and 22 can optionally be rotated into the working area have wear zones 23 which endanger safety. After appropriate inspection and cleaning of the wear areas 23 and after drilling new flow openings 21a and 22a on the closing surfaces 24 and 25, the worn flow openings 21 and 22 are filled with refractory material 26 and the filling on the sliding surface 27 of the plate 20 is smoothed, so that new ones Closing surfaces 24a and 25a arise.
