Definitions

  • the invention relates to an arrangement according to the preamble of claim 1 for casting metal anodes in an anode casting plant.
  • the invention relates to a conducting system for conducting molten metal from an anode furnace to an anode casting mold, where a metal anode to be further processed in an electrolytic refining process is casted.
  • the invention relates especially to casing copper anodes in an anode casing plant to be further processed in an electrolytic refining process, but the invention can also be used for casing metal anodes of other metals such as zinc anodes of zinc.
  • the copper process includes a step where blister copper is cast in a casting device into copper anodes for the electrolytic purification of copper. From a smelting furnace, copper is conducted and dosed to an anode casting mold by means of a system comprising chutes and troughs.

  • the chutes are installed with a suitable inclination, in order to allow the flowing of molten copper by gravity.
  • troughs for example a settling trough, in which the molten copper is poured from the smelting furnace, and where the motion of the molten copper is calmed down before conducting it to the chutes.
  • a dosing trough the task of which is to dose molten copper into an anode casting mold, as well as an intermediate trough for feeding molten copper into the dosing trough.
  • a conventional arrangement for conducting molten copper from an anode furnace to an anode casting mold is operated as follows: molten copper is first poured through the anode furnace casting hole to a settling trough, from where the molten copper is conducted along chutes to an intermediate trough. From the intermediate trough, the molten copper is poured to a dosing trough. From the dosing trough, molten copper is dosed to a casting trough, from which molten copper is cast in an anode casting mold.

  • the removal of copper build ups from the settling trough after each casting operation is hard and dangerous work.
  • Valuable refractory mortar is consumed in the repairs.
  • the repair mortar is water-mixed, wherefore the lining must be cooled for example by water to below 100 degrees before the repairs (in order to prevent the lining from boiling).

  • the chute support frame is movably connected to the support structure by a first lever arm and by a suspension element in the form of a second lever arm.

  • the chute support frame comprises a cradle, in which the chute is fitted.
  • the cradle is suspended, by means of a first suspension element and a second suspension element, from the chute support frame, so that the chute hangs directly vertically with respect to the ground surface, so that the symmetry level of the chute is always at right angles to the horizontal ground surface, with the melt flowing always in the same proportion to the chute profile, thus preventing the metal from being solidified on the cold chute wall.
  • the tracking arrangement comprises a roller that is fitted in the chute support frame.

  • the suspension element is an elongate bar element, the other end of which is by a ball-and-socket joint movably connected to the chute support frame, and the opposite end whereof is by a ball-and-socket joint movably connected to the support structure.
  • the arrangement also comprises a guide element that restricts and guides possible harmful movements of the elongate bar element in special cases, while gravity and supporting geometry normally secure the motion and thereby participate in realizing the motion of the chute downstream end with respect to the trough.
  • the chute upstream end can, owing to an arrangement according to the invention, follow the anode furnace casting hole in both the vertical and horizontal directions, a conventional settling trough, to which molten metal is poured from the anode furnace casting hole, is not needed in an arrangement according to the invention. This is due to the fact that in an arrangement according to the invention, the distance between the casting hole and the chute is small in comparison with conventional arrangements.
  • the arrangement according to the invention makes it possible to start and finish anode casting so that the currently normal removal of build ups from the settling trough is left out.
  • This solution is based on the fact that old metal can, owing to a movable chute, be flown away from the chute and from a possible chute cup that replaces the settling trough and is extremely small. In that case, an extra metal temperature is not needed for starting the casting operation, because the chute is hot and dry after the previous casting. Relinings need not be done.
  • the possible chute cap of a movable chute can be extremely small in comparison with the settling troughs of prior art arrangements. The profit from the lids is obtained through production security and energy savings, when the operational temperature of the anode furnace can be reduced.
  • the chute is movable, the chute can after casting be emptied for instance automatically, under the control of the tracking arrangement, and a separate removal of build ups is not needed.
  • a movable chute can be made self-emptying, so that after finishing the casting, the chute is automatically emptied of old metal under the control of the tracking arrangement.
  • the amount of metal flowing in the chute is essentially reduced when there is no settling trough. In that case, all of the metal flowing simultaneously in the chute fits in the intermediate trough. This is advantageous, because if anything surprising occurs and the anode casting machine is stopped, the metal surface in the intermediate trough does not rise too high, and it need not be cast to waste for emptying the chutes.
  • a smaller quantity of molten metal flowing in the chute in comparison with prior art arrangements, means that the automatization of the tilting of the anode furnace, so that the surface in the intermediate trough remains on a certain level, becomes essentially easier when the "intermediate storage" of current technology, i.e. the settling trough, is eliminated, and the molten metal flow reacts rapidly to the turning up of the casting hole of the anode furnace, for instance when finishing the casting or when adjusting the flow.
  • Another essential feature for the invention is that by means of the above described supporting methods, it is possible to make the conducting routes between the anode furnace and the intermediate trough as short as possible.
  • the chute route is must be designed to be, at least for the length of about 2-3 meters at right angles to the anode turning axis, before the route towards the intermediate trough can be designed.

  • the upstream end 29 of the chute 7 comprises a chute cup 26 for receiving molten copper 27 from the anode furnace 2, more precisely for receiving molten copper 27 from the casting hole 3 of the anode furnace 2.
  • the chute 7 comprises preferably, but not necessarily, a heating system (not illustrated) for heating the chute 7.

Abstract

La présente invention se rapporte à un système pour couler des anodes métalliques, comprenant un four à anodes inclinable (2). Le four à anodes (2) est pourvu d'un trou de coulée (3). Le système comprend un cadre de support de goulotte (9) destiné à soutenir une goulotte (7), et une structure de support (10) destinée à soutenir le cadre de support de goulotte (9). Le cadre de support de goulotte (9) est relié de façon mobile à la structure de support (10) par un premier bras de levier (11), de sorte que l'extrémité amont (29) de la goulotte (7) soit, pendant le mouvement d'inclinaison du four à anodes (2), placée au niveau du trou de coulée (3) du four à anodes (2). Le cadre de support de goulotte (9) est relié de façon mobile à la structure de support (10), de sorte que l'extrémité aval (30) de la goulotte (7) soit, pendant le mouvement d'inclinaison du four à anodes (2), placée au niveau du bac (8 ; 8a ; 8b).L'invention concerne également un système de suivi (15) destiné à guider le cadre de support de goulotte (9) pendant le mouvement d'inclinaison du four à anodes (2) par rapport à la structure de support (10), de sorte que l'extrémité amont (29) de la goulotte (7) soit, pendant le mouvement d'inclinaison du four à anodes (2), placée au niveau du trou de coulée (3) du four à anodes (2), et de sorte que l'extrémité aval (30) de la goulotte (7) soit, pendant le mouvement d'inclinaison du four à anodes (2), placée au niveau du bac (8 ; 8a ; 8b).
