Definitions
- the invention relates to a bottom lect for metallurgical melting vessels such as arc smelting furnaces,
- Resistance melting furnaces or ladle furnaces, with contact elements which ensure the electrical power supply through the refractory lining of the melting vessel into the melt and which are firmly connected at their lower end to a carrier plate.
- EP 0 058 817 B1 describes a base electrode with a support plate (base plate) arranged below and at a distance from the furnace bottom, with which the electrode necks are connected directly.
- the space between the support plate and the furnace floor has a central air inlet opening around which star-shaped curved air guide plates are arranged. In this way, a Heilz rkulat on is brought about for cooling.
- a bottom electrode in which a support plate connecting the electrodes is also arranged at a distance from the furnace bottom, the cooling air by means of two fans via controllable valves into the cavity between the furnace bottom and the Blown in the carrier plate, temperature sensors located in the bores of the contact points (electrodes) record the current operating conditions (temperatures) and control the amount of cooling air by means of a control and regulating device by regulating the valves and switching the fans on or off these operating conditions are adjusted. In this way, in particular during longer breaks in operation, the speed of the temperature change of the base electrode does not exceed predetermined maximum values.
- the measure of the invention to arrange a cooling space below the carrier plate, through which a preferably fluid cooling medium flows, and to arrange cooling fins in this cooling chamber, which are preferably welded to the carrier plate, ensures that a larger area to be cooled is available . This results in greater heat dissipation combined with a longer service life for the electrodes than in known cooling devices according to the prior art.
- the cooling fins are also attached to the cooling plate, for example by welding, so that in addition to the improved heat dissipation there is also the advantage of already installing the St Romansch Luss on the cooling plate.
- the cooling fins then take over the electricity transport - 4 -
- the contact elements are formed in two parts from commercially available profiled iron with a thicker lower part, the length of which can be adapted to the respective operating conditions and is preferably 200 to 400 mm, and a thinner upper part serving as a wear part, which is immersed in the melt and which is the actual electrical part Connects to the melt.
- This thin upper part is welded onto the thicker lower part.
- the length of the upper part depends on the lining thickness and is selected so that the upper end dips into the melt and thus creates the electrical connection to the melt. After the refractory material and the upper part have worn out, the old weld seam is separated and a new upper part is welded on.
- the increased thickness of the contact element Unterteili advantageously improves the heat input into the carrier plate and simplifies the separation between this reinforced lower part and the wearing upper part and its renewal.
- a gaseous or a liquid medium can be used as the cooling medium that flows through the cooling chamber. It is possible according to the invention, in particular when using a liquid as the cooling medium, to use the cooling medium at the same time for cooling the furnace vessel, as a result of which, for example, necessary funding can advantageously be shared; However, the prerequisite is that the furnace vessel is designed with a double jacket.
- the figure shows a bottom electrode 1 with a cooling space 4 according to the invention.
- contacts 3 are welded with their lower part 3 '(only one contact element 3 is shown) and then the thinner upper part 3 1 ' is fastened, the fastening preferably also being carried out by welding.
- a cooling plate 5 is arranged at a distance below the carrier plate 2, as a result of which the cooling space 4 is formed between the carrier plate 2 and the cooling plate 5, through which a preferably fluid cooling medium can flow.
- cooling fins 6 are welded to the carrier plate 2, by means of which the cooling surface is significantly enlarged and the cooling effect is correspondingly increased.
- the cooling fins 6 are also firmly connected to the cooling plate 5, as a result of which an additional cooling effect is achieved. Since there is thus a direct metallic contact between the cooling plate 5 and the carrier plate 2, this contact can also be used for power conduction.
- the current is supplied to the base electrode 1 via a power supply line 9 via a contact jaw 7 arranged on the tube 8.
- the current flows from the contact jaw 7 via the tube 8 to the cooling plate 5 About the cooling fins 6 to the carrier plate 2, from which the contact elements 3 produce the St romzuf flow to the melt.
- the cooling medium can be fed centrally from below through the pipe 8 to the cooling space 4 and then discharged again through side openings 10; however, it is also possible to use the lateral openings 10 for supplying and removing the cooling medium.
- the cooling fins 6 are shaped and aligned accordingly in order to achieve the greatest possible cooling effect with the lowest possible flow resistance.
- the invention is not only limited to the exemplary embodiment shown, but can also be applied to other exemplary embodiments of floor electrodes, insofar as there is the constructive possibility of creating a cooling space by arranging a cooling plate.
