Definitions

  • a lance changing arrangement for a top-blowing steel converter is described.
  • the vertical lance is supported from a carriage which is vertically movable along a stationary guide rail adjacent the converter.
  • the lance holding structure of the carriage is horizontally movable, either along an arc of a circle or a straight line, so that the lance may be moved from a stand-by position next to the converter, to the blowing position from which the lance is lowered into the converter mouth.
  • Two such lance arrangements may be provided for a single converter, so that the lances can be alternately moved into the blowing position.
  • the invention relates to a blowing device for a converter assembly having a lance guided along vertical guide means and adapted to be lifted and lowered.
  • the invention relates to a converter assembly having two such blowing devices, thus permitting an easy exchange of lances, e.g. for substituting a burner lance for an oxygen lance.
  • Another known proposal consists in a winch platform with two vertical guide means being horizontally slewable, the blowing position being located on the slewing path, so that the two lances can alternately be brought into operating position.
  • the invention has as its object to avoid the mentioned disadvantages and difficulties by providing a blowing device for a converter assembly, which blowing device is robust and easy to handle and which permits an auto- "Ice matic lifting and lowering and an automatic exchange of the lances, while there are no horizontal rails limiting or blocking the space above the converter, which is required for the exhausting and waste heat boiler installations.
  • the blowing device is characterised in that the lance is mounted on a carriage by means of a lance holder adapted to be horizontally slidable or slewable, said carriage being guided along a stationary vertical guide rail, the horizontal sliding or slewing path extending from the stand-by position to the blowing position centrally above the converter month.
  • the lance is lowered into the converter along the vertical guide rail by means of the carriage.
  • the lance may be fixed to a swivel arm which is supported on the carriage, or to a slide which is horizontally movable along said carriage.
  • a remote control shifting device is provided for effecting the horizontal movement of the lance holder.
  • two such blowing devices in symmetrical arrangement are provided.
  • FIG. 1 shows a plan view of two symmetrical blowing devices with slewable lances
  • FIGS. 2 and 3 show the corresponding front view and side view.
  • FIG. 4 the plan view of a modified embodiment with horizontally slidable lances is illustrated.
  • numeral 1 denotes the vertical guide rail rigidly fixed to the shop building, i.e. stationary.
  • the carriage 2 is movable by means of rollers or the like.
  • the lance 5 is mounted on the carriage 2 by means of a swivel arm 3 supported on a shaft at 4, and is slewable along the dotted are between the end positions R and B, R denoting the stand-by position and B the blowing position.
  • 1, 2', 3', etc. denote the corresponding parts of the symmetrically arranged second blowing device, where the lance 5 is movable from the stand-by position R into the blowing position B.
  • 6 and 6 stand for the remote control shifting devices mounted on the carriage.
  • the lance 5 is shown in blowing position and the lance 5' in stand-by position.
  • the lance 5 is fixed to a slide 7 instead of a swivel arm, said slide 7 being horizontally slidable within the carriage 2 by suitable means, such as rollers or the like.
  • suitable means such as rollers or the like.
  • the blowing device according to the invention is characterised by an easy and safe operation. When used in symmetrical arrangement as a device for the exchange of lances, it shows considerable advantages in comparison with the aforementioned lance exchange devices. In particular, the handicap of having to operate above the blowing position in order to establish alignment between upper and lower guide means, is eliminated.
  • the device according to the invention permits a favorable adaptability to the space available in the steel works by leaving greater freedom in the choice of a place for the stationary lifting and lowering means.
  • the employment of one stationary vertical guide means instead of the previously used two vertical guide means mounted on the lance carriage permits a considerable reduction in weight.
  • a blowing device for use with a steel-making converter having a mouth substantially at its top comprising, a vertical lance, a stationary guide rail adjacent the converter, a carriage mounted for vertical movement along said guide rail, and means on said carriage for holding said lance, said lance holding means being horizontally displaceable between a stand-by position in which said lance is disposed alongside of said converter and a blowing position in which said lance is disposed centrally of said converter mouth.
  • said lance holding means comprises a swivel arm pivotally mounted on said carriage.
  • Steel making apparatus comprising a converter having a top mouth and blowing equipment, said blowing equipment comprising, stationary vertical guide means adjacent said converter, carriage means mounted on said vertical guide means for vertical movement therealong, a pair of lance holders mounted on said carriage for simultaneous movement along a horizontal path, and a vertical lance carried by each of said lance holders, said lances being spaced apart relative to the length of said horizontal path such that when one lance is in an operating position centrally of said converter mouth, the other lance is in a stand-by position alongside of said converter mouth, and vice versa.
