Definitions

  • a scrap charging machine for converters is provided with which the ideal movements of crane charging are imitated and which is adaptable to local conditions. It comprises on a bogie chutes and chute carriers, and a crank mechanism for lifting and tilting the chutes.
  • the chute carriers include a fork-shaped part which receives the chute and is movable on wheels on the bogie so as to form a chute carrier vehicle, and tilting levers hinged to the fork-shaped part and the bogie.
  • the machine further comprises push rods hinged to the bogie and the tilting levers, and a stop between the fork-shaped part and the tilting levers. Upon actuation of the push rods the chute carrier vehicle is moved in a straight line in horizontal direction until the stop is reached, whereupon it is lifted into charging position and tilted.
  • the invention relates to a scrap charging machine for converters comprising a plurality of chutes supported on chute carriers, the chute carriers being arranged on a bogie which is movable preferably vertically to the tilting plane of the converters, and a crank mechanism for lifting and tilting the chutes.
  • a scrap charging machine comprises a bogie movable on the platform, on which bogie tiltable big chutes are deposed.
  • the scrap is supplied into the converter mouth by gravity via a curved discharge groove.
  • a further known charging means is described in the German patent No. 1,186,480: a scrap carrier vehicle is guided to the converter on rails which are arcuated downwardly for its front wheels and arcuated upwardly for its hind wheels.
  • the vehicle is moving to the converter during the entire charging process, i.e., also during tilting, so that scrap which comes to slide too early may fall beside the converter.
  • the rail paths have to reach until above the converter which fact necessitates greater structures and renders the plant complicated.
  • the invention is aimed at avoiding the described disadvantages and difficulties. It is an object of the invention to reduce the space requirements for the charging means and to render possible a tilting of the chute for which little height above the charging platform is needed. Further, the scrap charging machine should have an extremely wide lay out, the upper margin of the chute rear wall should have a small swing out height and the starting position of the chute should be low.
  • the invention is aimed at imitating the movements of crane charging which are in themselves ideal without having to provide crane paths with cranes. Such imitation should be achieved with simple means.
  • each chute carrier comprises an open frameor fork-shaped part receiving the chute and tilting levers hinged to said part, the frame-shaped part being movably guided by means of wheels on a bogie and the tilting levers beinghinged to the bogie, and in that push rods whose length may be varied are hinged to the bogie on the one hand and to the tilting levers on the other hand, a stop being provided between the frame-shaped part and the tilting levers, so that when the push rods are actuated the chute carrier vehicle is at first moved in a straight line in horizontal direction until the stop is reached and then it is lifted into charging position for emptying the chute and tilted.
  • FIGS. 1 to 4 illustrated subsequent phases of the charging process.
  • FIG; 5 a ground plane of the charging machine is shown
  • FIGS. 6 and 7 are a lateral view and a top view, respectively, and show details of how the chute is secured to the chute carrier vehicle.
  • FIG. 1 illustrates the beginning of the charging process.
  • Numeral 1 denotes a frameor fork-shaped part of the chute carrier vehicle which is movably arranged by means of wheels 3 on the bogie or main vehicle 5.
  • the fork-shaped part 1 is hinged to the bogie 5 by means of two tilting levers 4.
  • Push rods 6, whose length may be varied, preferably hydraulically actuated piston rods, are hinged to the tilting levers 4 on the one hand and with the bogie 5 on the other hand. When these pushrods are actuated, the fork-shaped part rolls on the bogie 5.
  • a stop 2 designed as a tappet is arranged on the forkshaped part 1. It engages with a tappet recess 11 on the tilting levers when the fork-shaped part 1 of the chute carrier vehicle is moved in forward direction, i.e., towards the mouth of the converter 9.
  • the bogie 5 is movable on the charging platform 10. On the bogie a plurality of chute carrier vehicles may be provided.
  • FIG. 1 illustrates the stage in which a chute 7 filled with scrap is deposed by a crane 8 onto the chute carrier vehicle.
  • FIG. 2 illustrates the following phase: by actuating the push rods 6 by means of the pressure cylinder the fork-shaped part 1 together with the chute deposed on it has rolled in forward direction until short of the engagement position of the tappet in the tappet recess 11.
  • FIG. 3 the period is illustrated in which the tappet is caught. From this position onward the tappet 2 blocks any further advance movement of the chute carrier vehicle. The own weight of the chute carrier vehicle guarantees a safe engagement of the tappet 2 in the recess 11.
  • the push rods 6 are further actuated the fork-shaped part 1 of the chute carrier vehicle is lifted off; it moves in a circular movement around its rotation axis to the converter mouth until the opening of the chute 7 extends into the converter mouth 9.
  • the angle of repose is obtained; the scrap slides into the converter.
  • the ground plan according to FIG. 5 shows that three scrap carrier vehicles may be arranged on a bogie 5.
  • Two tilting levers 4 are coordinated to each forkshaped part 1, one on each side.
  • FIGS. 6 and 7 illustrate how the scrap charging box is secured to the chute carrier vehicles.
  • guiding plates 12 are provided on the chute carrier vehicles in which lateral reinforcement plates 14 of the chute 7 are maintained in correct position so as to guard them against undesired movements.
  • On the chute carrier vehicle furthermore a lock 13 is provided which catches in a connecting link 15 provided in the rear lateral reinforcement plate 14.
  • part 1 is referred to as frameshaped part, but it is to be understood that such terminology is to include also parts having fork-shape or related shapes.
  • a scrap charging machine for converters comprising a plurality of chutes, chute carriers for supporting said chutes, a movable bogie for supporting said chute carriers, a plurality of push rods, actuator means for actuating said push rods, and stop means, each chute carrier including frame-shaped means and a plurality of tilting levers, said frame-shaped means being adapted to receive a chute and having wheels to form a chute carrier vehicle movable on said bogie, and said tilting levers being hinged on the one hand to said frameshaped means and on the other hand to said bogie, said push rods being connected to said actuator means and being hinged on the one hand to said bogie and on the other hand to said tilting levers, and said stop means being positioned between said frame-shaped means and said tilting levers, whereby when said push rods are actuated the chute carrier vehicle is first moved in a horizontal direction until the stop means is reached and thereafter lifted into charging position and tilted thereby emptying the contents of the chute into a converter.
