Definitions
- the present invention relates to an improved delta roof for electric smelting furnaces.
- the present invention relates to a delta roof provided with an improved integrated cooling system for cooling the electrodes that conduct the melting process.
- the present invention is mainly applicable in the iron and steel production field, in connection with the melting of iron scrap in electric smelting furnaces in which the roofs (delta) are utilised in such furnaces as closure elements.
- the delta roofs are provided with through-holes, usually three in number, which act as channels for introducing the electrodes.
- delta roofs As known, for reasons of transportability and movement of the delta roofs, these can be made as a single block of refractory material in the case of delta roofs of small dimensions, or as a plurality of independent but mutually complementary sectors, which will then be assembled at the mounting time in the steelworks.
- nozzles can also be provided directly on the delta roof at the inlet of the electrode.
- the aim of the present invention is to make an improved delta roof for electric smelting furnaces that is able to overcome the above-mentioned drawbacks of the prior art in a very simple, economical and particularly functional way.
- a further aim is to make an improved delta roof for electric smelting furnaces in which the periodical cleaning of the nozzles for cooling the electrodes, or the replacement thereof, does not require removing the delta roof, interrupting the production cycle and in general working under dangerous conditions.
- aims according to the present invention are attained by making a delta roof for electric smelting furnaces wherein channels are obtained directly in the refractory material, said channels converging from the outside in correspondence with the passages of the electrodes, wherein lances are housed in such channels in a sliding manner, said lances being provided with nozzles for cooling the electrodes.
- these channels converge towards the passages of the electrodes substantially horizontally or with an inclination of less than 20° with respect to the horizontal.
- Such a delta roof is at least partially made of refractory material and comprises at least one through-opening 15 for introducing from the outside an electrode for conducting the melting process.
- the delta roof comprises a plurality of channels 18 obtained directly in the refractory material in such a way that from the outside of the delta roof they converge at the through-openings 15.
- said channels 18 converge towards the passages 15 of the electrodes substantially horizontally or with an inclination of less than 20° with respect to the horizontal so as to be able to utilise the whole thickness of the refractory coating.
- a lance 17 is arranged inside each channel 18 in a sliding manner, said lance 17 being independently supplied with a cooling fluid and being provided with nozzles 16.
- nozzles 16 are arranged on the relative lance so as to face the electrodes for conducting the melting process when the lance is inserted in the channel 18. In case of cleaning or of need to remove a nozzle, it is sufficient to extract the relative lance from the delta roof, acting safely far away from the through-opening 15.
- end-strokes and angular orientation elements configured for guaranteeing the correct positioning of the nozzles with respect to the electrodes to be cooled are provided.
- At least two, preferably four, channels 18 are provided, so that, even removing a lance, at least another lance is in action with its nozzles on the relative electrode.
- the lances will be positioned more or less retracted with respect to the passage itself in order to prevent the rapid deterioration thereof.
- the accesses to the channels 18 are arranged laterally with respect to the delta roof and the inner walls of the openings are provided with holes 19 for the passage of cooling fluid from the nozzles to the electrodes.
- the present invention allows preserving the refractory material for a longer time, increasing the number of casts per delta roof.
- the temperature reaches about 1700-1800° Celsius, subjecting the refractory material to the melting limit thereof.
- the above-described system also contributes cooling the refractory material itself.
- the delta roof for electric smelting furnaces of the present invention on the one hand comprises cooling nozzles for cooling the electrodes and on the other hand does not require breaks in the production cycle for cleaning or removing them.
- the delta roof for electric smelting furnaces of the present invention as it is conceived is susceptible to numerous modifications and variants, all falling within the same inventive concept; moreover, all the details can be replaced by technically equivalent elements.
- the materials used, as well as the dimensions thereof, can be of any type according to the technical needs.
