Definitions
- the invention relates to a rotatable refining furnace for non-ferrous metals with an entry device for liquid metal, an adjacent oxidation chamber with a slag removal device arranged on the furnace jacket, a siphon formed by a partition wall and a reduction chamber communicating with the oxidation chamber with a metal engraving.
- the two processes can be carried out sequentially in one device, which leads to discontinuous metal production, or in two separate devices in a batch or continuous manner.
- a rotatable drum furnace which is charged with liquid copper and has an oxidation space, a detoxification space, a reduction space and a siphon formed by a vertical partition for separating the oxidation space and the reduction space.
- the slag is removed via a slag hole in the furnace jacket; the refined copper is discharged into a separate movable collecting container via a pouring spout arranged on the front side (DE-PS 810 432).
- a disadvantage of the process outlined above is that continuous operation is not possible since the collecting container has to be separated after it has been filled for the process in the casting installation and during this time the copper removal from or the inflow of metallic copper into the refining device has to be interrupted .
- Another disadvantage is that with the obviously intended use of small units, a constant copper quality cannot be achieved over long periods of time.
- the object of the invention is to eliminate the disadvantages associated with the construction of the known refining furnaces, in particular those mentioned above, and to provide a refining furnace which - with little construction effort - is simple to operate, permits continuous refining and the production of a practically constant copper quality.
- the refining furnace mentioned at the outset is designed in accordance with the invention in such a way that that the metal engraving 7 is arranged on the furnace jacket on the side of the slag removal device 5, but lying deeper.
- the arrangement of the slag extraction device and the metal engraving on the same side of the furnace jacket and the rotatable design of the refining furnace make it possible to carry out oxidation and reduction treatment with a largely arbitrary filling level, so that the refining furnace also acts as a collecting container or has a considerable buffer capacity on metal inlet and tapping. For example, by rotating the refining furnace in the sense that the slag extraction device and the metal engraving reach a higher level, metal can be taken up for the reduction and oxidation treatment if less metal than the feed or no metal is to be released.
- the refining furnace according to the invention is in a range from approx. 30% to. 100% of the highest possible degree of filling operational.
- the operation of the refining furnace according to the invention with regard to oxidation and reduction treatment is carried out in a manner known per se.
- Air, oxygen-enriched air or technically pure oxygen can be used for oxidation, and the known polar agents, such as powdery and liquid reducing agents, carbon monoxide, reformed or non-reformed hydrocarbons can be used.
- the reactants can be introduced via nozzles, optionally arranged as rows of nozzles, or lances, which can be water-cooled, for example.
- the metal engraving has a drain box which is attached to the furnace jacket and runs practically perpendicular to the furnace axis and can be closed with a stopper.
- the amount of copper flowing out can be regulated very precisely by operating the stopper as a valve.
- a further advantageous embodiment of the invention consists in providing a tilting device which moves the refining furnace about the furnace axis in the vertical direction. This in particular provides the possibility of optimally adapting the levels of the slag removal device and metal engraving and thus the slag layer thickness to the respective operating conditions.
- At least one burner on the end face opposite the inlet for the liquid metal, as a result of which not only the required temperature in the refining furnace but also the oxidizing or reducing the furnace atmosphere can be adjusted by changing the fuel-air ratio.
- the embodiment of the invention according to which the feed device for the liquid metal is guided through the exhaust gas opening of the refining furnace arranged centrally on the end face, is associated in particular with the advantage that the furnace exhaust gases give off part of their sensible heat to the incoming metal and thereby extensive use Experienced.
- the refining furnace according to the invention is suitable for the treatment of all of the non-ferrous metals which first require an oxidation treatment and then a reduction treatment.
- An important application is in the refining of copper.
- FIG. 1 has an oxidation space 2 and a reduction space 3, which are communicatively connected by a partition 4 forming a siphon.
- the slag removal device is designated by 5. It has a slag dam 6.
- Figure 7 illustrates the metal engraving, which is provided with a drain box 8 and stopper 18. The metal feed takes place via entry device 9, which is guided through the exhaust duct 10. With 11 a burner is designated.
- the rotary movement of the refining furnace 1 is effected via rollers 12 which are guided on races 13.
- 14 represents a nozzle for supplying oxidizing gases
- 15 represents a nozzle for supplying the reducing gases.
- the metal engraving 7, the drain box 8 with stopper 18, the nozzle 15 for introducing the reducing gases, the gas extraction device 10, the rollers 12 and a race 13 are shown.
- the refining furnace 1 is shown schematically with the tilting device 16 moving the furnace axis in the vertical direction. With 17 a closable opening for opening and closing the stitch 7 is designated.
- the refining furnace 1 used in the example has a total length of 9.50 m and a clear diameter of 3.50 m.
- the length of the oxidation space 2 is 6.50 m, that of the reduction space 3.00 m.
- the maximum degree of filling of the refining furnace 1 is 250 t, due to the flue gas duct 10 arranged centrally on the front side.
- the increasing copper content is taken into account by a corresponding rotary movement of the refining furnace 1.
- slag is removed continuously or at short intervals via the slag removal device 5 by overflow over the slag dam 6 in quantities of 1000 kg / h.
- the casting process is stopped for 4 hours with a filling of 130 t, as a result of which the amount of copper in the refining furnace rises again to 250 t.
- the gas quantities supplied to the oxidation space 2 and the reduction space 3 can be kept constant within the entire test campaign described.
